Title: Vibration on braking
Post by: Mk5341 on October 31, 2022, 07:33:24 pm: Hi guys

I'm new to the forum recently bought myself a mk5 gti
I'm getting a bad vibration on braking in the steering wheel but not so much in the pedal
It has audi s3 brakes on it and drilled discs but they seem OK not warped and it has polybush console bushes (i think thats the name for it... the ones on the lower arm in the ally casting) which I can't seem to find any play in
Does any1 have any ideas as to what else I can look at cause I'm pretty stumped now I have no play in anything

Cheers

Vibration can also come from buckled wheels, or unbalanced wheels - but you'd get that all the time, not just under braking.

I guess I'm going to have to get them checked again
Might just buy a new set to eliminate it completely

What you are feeling most of the time is pad deposits, often because brakes have overheated.

I’ve had luck using proper brake pads (with a high metallic content) in the past to fix the issue.
