Title: Standard brakes
Post by: edd666999 on December 13, 2010, 06:40:19 pm
What would you say the max power you should run using standard brakes?

im only asking because i have seen a gti for sale with 379bhp and 360lb ft of torque on standard kit....i thought its a bit mad, or am i underestimating the standard stuff?

The standard brakes are very good. The difference compared with a good aftermarket big brake kit is that pedal response will feel that much better and stopping power delivers greater de-acceleration. Also, if/when you are using your brakes a lot and quite hard, the oem brakes will fade sooner than aftermarkets will.

Much depends on how hard you drive and how often you drive that enthusiastically but a 380bhp GTI will lead you on!

Standard VAG brakes are well-known for relative poor pedal feel.

I would say that 300+ bhp on the standard 312mm is fairly irresponsible unless your using very good pads (although i'm sure many do it)

The standard brakes were one of the things that I felt let down the car... IMO even upgrading to the R32 fronts will make driving the car feel much safer!  :happy2:

I must admit even standard the Edition 30 is too much for it's godawful brakes.

Better brakes = best mod IMHO.  :smiley:

All Gti have bad brakes it's Part of the DNA of the Gti golf trust me have had every Gti model out and the stock brakes on all of them are ok but when pushing more power and giving them a big workout stock brakes suck arse  :driver:

I don't think the standard brakes are even up to the standard GTI's 200bhp, let alone the Edition 30's power. I would never have even remapped my GTI without replacing the brakes first.
When I went from a BMW to the GTI, the first thing I noticed was how poor the brakes are. All BMW's with reasonable power have excellent brakes as standard but VW's seem to really lack in this area. Even a 1.6 Focus has better brakes than a mk5 GTI in my opinion and I just can't understand why VW do it  :confused:

I assume your talking a new 1.6 focus Garth, my MK1.5 focus 1.6 had really dead feeling brakes and absolutely no bite and I had the reflex pac with all round disc ABS and EBFD  :laugh:  My right leg used to get a fairly good work out though!!!

I was rather shocked when I changed the pads in the front of the GTI that the lovely red calipers were more show than go, other problem ive had with GTI brakes is the emergency brake assist cutting in too early, I had to jab the brakes on a dual carriage way and the quick jab was taken as an attempt at emergency braking by the car  :scared:  Was nearly very dangerous as someone was driving up my chuff

When you've got much more powerful brakes you have to be especially aware of the vehicle behind you and realise that some drivers rely on seeing your brake lights before they brake. If they can't de-accelerate as quickly as you do, you could have a rear end impact. However, I've noticed that once a car behind has realised your extra braking power they tend to stay further back which is a good thing.

Probably because of being my generation, I tend to shift down the gearbox (Manual in DSG) when slowing rather than only rely on braking. I don't like to see drivers constantly hanging onto their brakes all the way down a hill or before every single corner when only doing 40mph! "Oooh, there's a bend - I must brake" :fighting:

I dont think its just your generation Robin, I think its just people who can actually drive I will always use engine braking down big hills and it drives me mental how some people think there cars can only take corners at 5mph IMO there are a lot of people on the road that have no real concept of driving, not how to pass a test but how to safely drive a car such as anticipation lifting off the throttle rather than always on one pedal or other and progressively steering a car so that you can safely take a corner at speed, and I wont even start on people lane discipline on roundabouts!!!!  :fighting:

....Oh yes! Roundabouts! I had one yesterday while I had a Police car on my tail and he didn't stop and caution/educate them. Probably because he was intent on following me, so I decided to drive enthusiastically but absolutely within the law - The Quaife diff works very well on greasy road surfaces on roundabouts!

It's strange how one builds up a sixth sense and intuition about other drivers behaviour and then anticipates it. If there's other traffic on a roundabout I always assume they'll do the worst. I've actually gone completely around a roundabout to avoid someone cutting across me from the lefthand lane!

No im sure it was far more important to keep an eye on you incase you crept over the speed limit as your car is modified so your bound to drive like a t1t, rather than the twonk in the soft roader who doesnt pay attention to road conditions other road users or look more than 5 metres in front of there bonnet while driving around on dangerously bold and under inflated tyres and hasnt ever lifted their bonnet to check the car is roadworthy.....  and since its always dark I will add the ones who aren't aware of what the little dial to the right of the steering wheel is for so drives round shinning there headlights in your eyes. 

Sorry I will stop now  :signLOL:

Funny how they dont tell you that when you learn to drive, and yet its the best single piece of advise you can give a driver!

Assume people will cut across the roundabout
Assume people will pull out on you at junctions
Assume BMW drivers will do what the hell they want and then try to blame you....  :P

....At the risk of sounding pedantic, I'd say " Assume people might" rather than "will", as otherwise we'd be behaving like scared rabbits.

Not in my English lessons! We're talking about a possible event in the future, the subtext in the use of assume removes the hypothetical, in my eyes anyway - your behaviour is permanently altered in anticipation of risk.

Shaved from t'net.

May and Might – "May" should only be used where the event in question is still possible, not for something that was possible in the past. "Might" is properly the past tense form of "may". (In similar fashion, "could", "should", and "would" are all past tense forms for "can", "shall", and "will", respectively.)

LOL - we're waaaaay into the realms of off topic now!!

Oh, and 312s on that car say scene-mobile. Pub bragging power with no concept of a true fast car.

Fair and valid point.... english were never me strong point!  :innocent:

.... we digress!

For what it costs to upgrade to the R32 front brakes, i'd say that anyone with a GTI should seriously consider it. They are night and day compared to 312mm, they actually have initial bite which is something that my 312 lacked.

As for running anything like 350+ with 312mm....  :fighting2:

Are the R32 single or dual pot?  Yours that were loving refurbed by dave are single but google image search shows some as 2 pot is this a difference between Mk4 and Mk5?
Title: Re: Standard brakes
Post by: MAT ED30 on December 15, 2010, 02:16:28 pm
Mk5 is single pot piston it's mainly the bigger disc your paying for with this set up
Title: Re: Standard brakes
Post by: rich83 on December 15, 2010, 02:48:18 pm
MK5 R32 is a single piston like mat said above... 57mm i think!

MK4 R32 is a double piston!
