My edition 30 is going stage 2 soon and I feel i will need some better brakes.
I dont fancy spending a fortune of big brake kits and I've heard the r32/s3 brakes can be too heavy. Could i just upgrade the pads and change the brake fluid?
-
you can R32 setup but get Audi TTS Discs, they are lighter than r32 discs.
I ran these on my old gti and you feel the difference in the steering.
Ill have an r32 setup coming off my current car soon if youre interested?

What would the r32 setup consist of and do you have the tts discs coking off your car too?

R32 Brake Calipers, carriers, Discs, pads and braided brake lines.
Ive not got the TTS discs on mine, not sure what brand they are but they dont seem heavy compared to my old r32 setup I had so just left them on.
-
The R32 brake setup is more than enough for fast road use, quite cost effective and the weight penalty isn't too much of an issue especially if running after market alloys which are usually lighter than stock items anyway.
The next upgrade to consider would be the Porsche 986 Boxster front caliper upgrade. This is probably one of the most popular multi-piston, lighter caliper upgrades for the Golf/Audi/Leon platform with loads of support for it from tuning companies.
Ultimately, you can do what I did and go for the Porsche Cayenne 6 piston upgrade. Cost me around £1000 in parts and I fitted it myself to keep costs down but it's more than capable of big power in a Golf/Audi/Leon.
-
Get a used R32/S3/Cupra setup for £300 ish. Best value for money brake upgrade you'll find.

Don't forget to add it's also the cheapest and easiest kit to maintain in terms of parts too.

Will he notice the added weight tho.
Will the ride be more crashey only reason that puts me off is the added weight and how it will fill behind the wheel.

The added weight might be only noticeable just after installing the calipers. You soon get used to it. The ride quality will keep the same, IMO. I have this setup on my GT Sport, BTW. :smiley:

R32 calipers are ridiculously heavy. The 2 piece discs aren't too bad, but still heavier than 312s. Some of the weight gain can be offset by fitting Passat bearing carriers and wishbones, and also the driver eating fewer pies :smiley:
Brake the car appropriate for it's purpose. The amount of crazy disc and caliper combinations I see pop up on the facebook group is nuts, and most of them for sale. Lambo 8 pots, Audi 6 pot ceramics etc etc. It's just nuts. 90% of these combinations are thrown on for kerb appeal and bragging rights, with no thought given to Master cylinder volume, brake bias, rotational mass or wheel clearance. OEMs fit brakes appropriate for the car's mass, performance and tyre width. No Golf running 225 section tyres will even realise the full braking potential of Lamborghini 8 pots and 390mm discs :grin:
If it were me, I would go MK7 GTI caliper with TTS 340mm discs, along with the aforementioned Passat alloy items. You'll get the benefit of stronger braking, but without a weight penalty, minimal increase in rotational mass, and more flexible wheel choices.
-
I feel an huge braking power difference between my R32 front calipers with TTS Brembo Sport 340 mm discs and my Brembo 18Z calipers with MB ML450 350 mm discs.
My GT Sport has the smaller MC so it's working at its maximum. I never floored the brake pedal while hard braking. I do know that when the pads are worn out the brake pedal will have much more travel.
My Ed. 30 has the bigger MC and works well with the Brembo 18Z that have a smaller piston area than the new GTI PP/7R front calipers. Keep in mind that the 7R has the same size MC as my Ed. 30.
I do notice the heavier brake discs compared with the TTS brake discs. On track the setup has never faded yet. The increased mass helps to dissipate the heat too. I chose these calipers due to being able to fit lightweight wheels without needing wheel spacers, being cheap and a direct fit to my hubs.
I reckon that I don't have the same flexible choice on discs or pads for track use but I have plenty of cheap options for daily driving. These calipers being so close to the hub make them incompatible with the SuperPro adjustable ball joints and with alloy hubs.
Bottom line is, choose wisely the brake setup for the intended use. :smiley:

You are a shining example of the opposite of "What do I need to make these 56 pot McLaren P1 calipers fit my Ed30?" type stuff that seems to be the culture these days :smiley:
I have yet to find a requirement to move away from the standard brakes. I don't do track days, because it's a road car.....I'll buy a Caterham when I do track days :smiley:
I think most folk who feel the standard brakes are inadequate for road use....
...are driving way too fast on public roads and / or leaving the braking way too late.
...have f'cked rear calipers.
...have a vacuum pump seal leak.
...have crap pads.
...have worn dampers.
...etc.
Seriously, I have braked from some pretty silly speeds I'm not proud of and the standard brakes were absolutely fine. Bigger brakes improve the initial bite because of the torque leverage and bigger pad area, but you cannot deploy more stopping force to the tarmac than the tyres are capable of. Standard brakes can lock the tyres just as easily as massive brakes. The only difference is pedal effort. I'd rather save my money and push the pedal harder :smiley:
-
Yeah but big brakes.... they are big :ashamed:

They are :smiley:
Trouble is, the bigger the disc, the more flywheel effect it has at the end of your driveshaft, which isn't pleasant on FWD cars. 18" wheels are bad enough for that as it is!
-
Kind of true, unless you are using lightweight 2 piece discs. The steering on my car noticeably got lighter going from solid 340mm to 2 piece 362mm.

I hear that but oem are still sh*t in comparison to BBK's or else why we fitting them. A lot of people use oem calipers and a good set of pads but I prefer a bigger set of brakes because the wheels won't swollow the calipers and discs so looks much better and greater stopping force for me remembering we're upping the torque so will need more braking force for that power band.

At high enough speeds the OEM brakes can't lock the tyres, even if you stomp the brakes as hard as you can. But for road use only the R32 and 7R brakes are plenty enough. If you want a lighter setup the NQSBBK should be the best option.
Just the track use requires a bigger and better setup. :smiley:
-
I've managed to overheat the standard 312s (standard disc and pads) on the road, but I am a heavy on the brakes. They bite and stop well, but fade seriously quickly after a few hard stops. S3/R32/Cupra 345mm setup I've yet to experience significant fade although spirited driving is on hold at present until other issues are resolved.
At the end of the day its a standard setup on the Leon Cupra at a 'mere' 240hp so its hardly overkill for a stage 2 Ed30 with 100hp+ on top
-
I'm in the process of getting good track use only pads. Chose the Carbotech XP20. I'm sure it will come the time when I'll want to get 2 piece disc to decrease the weight on my front axle.
-
I found the standard brakes were really quite easy to cook. Fade was never far away. Actual stopping power was quite good, but only for a few big corners.
The mk7 PP/Clubsport setup I've got now deals with heat much more competently. Stopping power is moderately improved, but that wasn't the main factor in upgrading. It was to improve the resistance to fade. So that's the box ticked.
They're adequate. No more, no less.
There's nothing wrong with bigger 4/6/8 pot kits, as long as the piston area is within tolerance of the master cylinder. Dedicated track cars might find the limits of the mk7 setup a little too quickly. And a good kit with two piece discs does look the b*llocks, you can't deny it.
EDIT: Just realised I've pretty much just rewritten what Dan said! Seems a common theme, anyway: It's not the braking force, it's the fade.

Exactly. You cannot deny that big brakes offer better braking and shorter shopping distances.

Yep, very true. The key words there being "high enough road speeds", where the stock brakes can't shift enough heat. I'm not disputing bigger brakes aren't needed on track days and I agree they look cool and can work brilliantly if sized correctly, but in the context of road driving - if people are over cooking standard brakes, I think it's more a question of driving style than a braking deficiency and it's only a matter of time before they come a cropper. If people push the limit with standard brakes, they will push even harder with uprated brakes, and the consequences will be even worse. That's why insurers bump up the premium for bigger brakes.
There isn't much significantly better than the PS4 at the moment. Doesn't matter how grippy the rubber is, 225 section is 225 section. For example, you will never get 911 GT3RS stopping power from bolting 911 GT3RS brakes onto a Golf. The 911's chassis was built to deploy that stopping power, the Golf's wasn't. And that's the issue I have with bolting on random disc / caliper combinations from various makes of car because it can often give patchy results.
I've had AP Racing kits in the past and I do like silly powerful brakes, but I wouldn't spend that kind of money again on a road car because I don't think the cost / benefit ratio stacks up on the road, unless you get a hard on from braking as late as possible of course. Something cheaper like the MK7/340mm setup makes better sense for a road car.

My leading pistons are the smaller ones at the top and was wondering if I was to swap the pipes and nipples over so that the bigger pistons are at the top and would there be any difference in braking?.

I cant answer you R5GTT, but I'll just chuck my tuppence in here on the R32/standard brake thing. I have a standard Ed30, road use only, and I was horrified with the standard front brake set up. My problem was that increased brake pedal pressure (in those emergency "oh sheeeet" moments), had no effect on stopping power, it was like pressing on a lump of wood. I wondered if I had a problem, put on new discs, pads, checked everything - same terrible braking. Fine for 30 to 40 mph town use, but nothing else, and in my opinion dangerous for emergencies.
Swapped to R32 calipers with braided hoses and 340mm TTS discs - halleluyah! Brakes again! (I came from a MK2 G60, with standard 280mm front brakes and single pot calipers, so that it was I am comparing to) .
Yes, the calipers are heavier, but the only difference I initially noted was on steering feel, no big deal at all.
Weirdly the R32 pad area looks to be the same as in the standard ED30 caliper, the huge caliper size difference is due to a supporting framework around the caliper, i presume to reduce twist , allowing more braking force to be applied. Plus of course the force is being applied to a 340mm disc, not a tiny little 312mm, and perhaps the caliper piston is bigger.
Well worth putting the brakes on.
(Presumably VW had run out of money on the ED30 and ignored the brakes, the R32 only has 20 bhp more, is heavier, but came with bigger front and bigger rear brakes as standard. )

You want the small piston at the top, for cars that have the caliper on the front of the hub.

i would agree about the poor braking with oem ones as I've had this with other cars so definitely the way to go. :happy2:
The pad sweep area are the same but the pistons on the R brakes are bigger so better for braking force allowing the car to stop a lot quicker :driver:

thank you for that @Shoduchi (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10590) I've read the thread yeR back but didn't save it but very informative and I think I'll be fine with the way they are now as mine are turbo front calipers and not boxster rears so it won't really matter which way round the pistons are although I was told differently by the refurb specialist in Nottingham or was it Coventry off facebook a while back and when I was looking at my calipers last night wondered if it would make any difference. :happy2:

Thanks @rich83 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=709) was told different but then again there would be no difference as our brakes are front hub mounted as I've now realised reading that thread Shoduchi posted that some rear calipers are fitted at an angle so the bigger pistons would sit forward.
-
Nothing to do with angles. It's to do with the small piston being on the leading edge of the pad
-
It may have been said already but you can offset the better S3 brakes weight by fitting the allot lower arms found on some passats, cupras or the SuperPro version :)

As far as I am aware the S3 wishbones are just 1kg lighter than standard GTi ones.

They are definitely lighter that's for sure but was told they are slightly longer on the ends unless anyone else can confirm otherwise as it will make my life a lot easier just fitting the complete bones with the superpro on.
Thanks

The S3 and Passat LCA are completely compatible. The TT LCA aren't.

Have you driven a MK1 GTI or Corrado VR6 with standard brakes? Seriously, you have not experienced crap brakes until both of those boxes are ticked!
I came from a Corrado and the standard MK5 brakes nearly put me through the windscreen by comparison :grin:
Correct, the R32 may only be 20hp more but it has 200Kg more to stop, hence it's brake sizing. I know I am on my own here, but there is nothing wrong with the standard MK5 brakes at all if all 4 corners are in fine working order.....and that comes from someone who's experienced AP Racing brakes on VWs in the past.

Explanation found online:
"Notes on increasing piston size purpose.
1. Large pads get hotter/wear more in their leading edge, leading to taper and performance issues as the leading edge overheats under very hard use (read: track)
2. The way the progressive piston sizes work, is by putting less pressure on the leading edge of the pads. Think about it, if pressure is expressed in psi, less square inches equals less pressure."

"Notes on increasing piston size purpose.
1. Large pads get hotter/wear more in their leading edge, leading to taper and performance issues as the leading edge overheats under very hard use (read: track)
2. The way the progressive piston sizes work, is by putting less pressure on the leading edge of the pads. Think about it, if pressure is expressed in psi, less square inches equals less pressure."
ahh thanks for that @Shoduchi (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10590) wonder why that caliper reconditioning guy told he'd turn the pipes and nipples around as I didn't quite understand him :stupid:
