Hi

Just looking for some advise on where to start with this problem.
I fitted Reyland discs all round less than a thousand miles ago floating front / fixed rears with red stuff pads
Fitted them as had some wheel wobble on braking and old discs had done 50 k.
The wobble is still there but now under heavy braking the car really shakes the steering wheel.
My local garage who I know well said the suspension had no play so really confused.
Any suggestions would be appreciated on where to start trying to solve this.



Cheers

Darron

I would be looking at the wheel hubs. If theyve got any corrosion on them . They should be spotlessly clean before mounting the discs and then at the wheels for deformation etc

I had this when I fitted Redstuff to my standard 8P discs many moons ago.

After a few days I’d get terrible vibration through the wheel.
Cleaning the discs etc with the jet wash and it stopped but only for a few days.

Do yourself a favour and get shut of all the crappy Redstuff pads for something better like a Ferodo pad.

Darron.

If you were running Redstuff on your old discs more than likely that is the root of your problems.

As it been said before just change make of pads....Ferodo premiers are a good road pad & can be picked up off eBay for roundabout £45,give them a try & see if they cure the wobble.

Btw if you do change pads give the discs a good clean to remove all of the old pad material.

I cleaned the hubs they were spotless when mounted the discs on. After what’s been said I think I will try new pads first cheers

I had a similar situation a while back. Got the discs skimmed with new pads and it was night and day with no wobble/inconsistent grabbing afterwards - even to this day a couple of years on

Chris.

There new discs fitted with less than 1k so skimming shouldn't be required & I can vouch for Reylands robustness as I've done numerous trackdays running DS2500s.

Imho the problem lays with running EBC reds not the discs.

Just an update on the wobble vibration sorry for the delay.

The wobble vibration has been improved by changing the pads it is still there slightly but nowhere near as bad.

I found that the pads I removed were in a bad state and crumbled slightly causing a groove on passenger disc.

I have contacted EBC regarding this and they have had the pads back for testing.

So awaiting the outcome.

If after a few hundred miles car has a slight vibration still I will probably book it into awesome gti as the last 2 garages that I usually deal with have both said no play in any suspension joints.

The disc with the groove is cleaning up so hopefully won’t need to be refaced as spoke to Reyland

Here's a set off Reds I fitted some years back 😂 Not that suitable for our RSs tbh.

Jesus not good.

Hopefully the wobble will eventually go after the pads have had a few miles on them. If not then I will have to take it into somewhere but I have awesome not to far from me so will get them to look over it.
I need someone to look over the car anyway as I want to know what has been done in the past as when I bought the car it was meant to be standard apart from a cat back and it’s far from that.

Just bide your time in regards the brake pads/wobble.....mine were shocking after a track days but disappeared after some miles/time.

Tbh I found the Reylands to be very good even after a good work out on 2 track day braking from 150s at the end of a 1km straight for a 70mph chicane with DS2500s fitted.

Tbh I think the Reds didn't suit the Reylands which can happen with any disc/pad combo.

Just to give you guys an update after returning the pads EBC said the pads were fine and thought the damage was caused by stones or grit.
Told them I dismantled the brakes and it was the pad material that caused the disc mark. They have refunded me for all pads and after further discussion they have agreed to pay for replacement discs also. Happy with the outcome

Great outcome 👍 I remember having a conversation with Martin @ Reylands he didn't speak highly of EBC pads & normally recommends Ferodo pads mate.

Another member on here also had problems with Reds on his Alcon discs.
