266mm brakes Vibrating as speed?

[Claki]

My 206 Gti brakes Vibrate quite hard above 60 i cant work out whats wrong. i do have grooved disks but thats shouldnt be causing that?

[Woody91]

Could be slightly warped discs do they judder when your slowing or coming to a stop?

[Claki]

no its only above 50. it must be somthing to do with the discs not being straight or fitted correctly... although it did seem to be worse on my way home today.

[PhillipM]

Is it judder, or just noise?

[Claki]

bad judder

[PhillipM]

Right - grooved discs can be noisy at higher speeds, my wavy discs are too.
Pad deposits so the discs feel warped/rust behind the disc on the hub/loose wheel bolts/dying wheel bearing.

In that order ;)

[Woody91]

could be a slight warping or the discs fitted wrong try taking them apart and refitting them see if it solves the problem

[Mikol]

Always good to just take it all apart and refit, just to be 100%. Whilst you're down there grab some blue-roll or something and just clean any stuff off the hub that might have built up over time.

Then re-fit with a small amount of copper ease if you like and make sure everything's torqued up properly :)

Tbh my car always vibrates around ~70mph. Brake judder isn't really noticeable which is surprising considering my 266's are bodge-tastic.

got the caliper and carrier bolts on tight?
If its making a horrible noise to, sounds like discs are warped.

[PWA]

Agree with Steve, sounds like your disc is warped.

[Claki]

Yeah I had to take the carriers ect off recently due to an accident and they were very tight comming off and I put them back on just as tight. I will take them all apart, clean and reassemble just to be sure. And another ting is, they do try to pull left under heavy braking along with the judder. Just to be clear the judder comes with quite seveere steering wheel wobble.

[LEE_VTR1]

have you been braking hard alot lately. sounds very much like warped discs to me iv just swapped my disks because I'd warped them

[DJDannyB]

I had the exact same problem, i think the discs got warped when bedding in, so i fitted a new set of discs yesterday.. see how they go

[toxic]

its your nuts m8

[mantahatch]

Could it be wheels out of balance ? and as for the pulling to the left while braking, could that be a siezed brake caliper ?
