Got a bit of shaking going on when braking.
Has anyone had issues with Brembo discs warping at all?
upgraded the fronts to mk7r 340s, rears are standard.
What other make of discs are ok? Ate has been mentioned.
Just road use, and not ragged much at all so if they have warped then that pretty poor....
Cheers.

New discs or 2nd hand with the 7r calipers? I've put my old brembo discs through he'll on my old std setup on Road and on multiple track days and they were the only thing that didn't fail on that setup. They are generally good quality.

My Brembo rears warped pretty soon after fitment :grin: Rears ffs, they only do 30% of the braking and they still warped :grin: :grin: :grin:
As we've discussed before, everyone thinks of giant Lambo/Ferrari brakes whenever the word Brembo comes up, but they sell cheap junk in the aftermarket like a lot of other brands. Just for reference, my Brembos (and pads) were the standard spec ones from ECP and both are terrible. Not using them again.
Lewo - go ATE or genuine VW. And make sure the hub mating surface is sanded back completely flat before fitting a new disc onto them.

I’ve been using EBC turbo groove discs for a while now and they have stood up well. I know EBC haven’t got a great reputation but I think in recent years their quality has improved significantly.

Never had brembo HC discs warp. They seem well made to me. As pudding alludes to, not all brembo are made alike

Good shout about sanding back the hub. I uually put a smear of copaslip on those faces .

Not heard of Brembo HC, these are different from the standard Brembo?

Can’t remember exactly - got them from https://www.ebcbrakeshop.co.uk/ with a 15% discount they were offering at the time. Watch you get the right size - rears are 286mm (they also sell a 260mm which didn’t fit my Eddy).

High carbon variant.

Yeah get them clinically clean as its surprising how little dirt on the hub face can cause major disc run out.

My brembo rear discs and pads are perfectly fine. Go with what you like and a trusted brand I say.
Forums will always have lovers and moaners of the same subject.

Copper grease is made up of copper filings - so not ideal between disc and hub.
ceramic grease or nothing would be better choices.

I use aluminium antiseize. Works great and means nothing gets stuck.

Cheers, will look into getting some when covid has gone somewhere else!

Yes - I just got a tub this year - the way it coat your hands is hypnotic!
think would work really well within aluminium -thinking subframe bolts.
-
Anti seize bought.
An idea, maybe a stupid idea but.....would it be worth clamping the bake hose on each caliper one at a time and test on one of the many quiet roads around here to see if that shows up the offending brake/s?
Would the clamp hold ok under braking pressure?
-
I wouldn't do that mate, it's brakes man :grin: If someone pulls out in front of you and you can't stop, and the rozzers see a clamp on your brake hose, yeah, that could be a bad day for you :grin: The clamp probably wouldn't do a lot anyway tbh!

Gotta catch me first.... In a ditch on the first bend :signLOL:
Was just a thought, but not a good one it seems!

can you put up any pictures? so we can see all 4 faces of the discs.
stuck caliper might show blueing on disc, or even pad deposits (which can also cause wobble)
you say new calipers and discs but new/ s/h pads and if so what make? did you follow break in procedure?
have you checked your wheel bolts arent loose?
could take it all off and cleanup and clean mating surfaces.
if pad deposit then an italian tuneup with cooldown
would seem unusual to have a disc warp in this way given what youve described tbh (unless youve ragged it then came to a stop and held the brake pedal down for ages (to let discs heatsoak into pads etc)
