Vibration under braking (NOT Discs though)
 

Hi There


I have intermittent Vibration/wobble through the steering wheel under braking sometime light sometimes heavy to the extent you feel it through the seat.


It is very intermittent but does seem more often if sudden braking straight from hard acceleration !
However emergency stops from normal cruising at any speeds shows no vibrations


The discs have be checked and are not warped (so I am told) leaves me at a loss of what it could be.


Any help appreciated

Pads breaking down?

Discs
Pads
Pistons
Ball Joints
Drop-Links

Might be worth checking the lower arm bushes also.

tracking tyres tyre pressure plus crud between the disc and hub off setting the disc

Tighten those wheel nuts!?

First, rule out the basics; Swap the front wheels with the rear (and correctly torque the nuts).

I've had to change my steering rack bushes as I was getting the same problem I thought it was my discs but it tuned out to be the rack

What brake pads are you using??

I had a similar problem a few days after i had my sti. It turned out the garage had put the cheapest pads they could find on the front and put the shims the upside down. Put good pads in then rebeded them all ok since

Hi Thanks for all the comments


Wheel have been swapped front to rears and the issue stills occurs,


The Pads where an expensive make cant remember which make as they were fitted by Power station when they existed along with new discs. will have to find receipt and see. ( the new Disc and pads haven't done 1500 miles )


It is going in a garage next week to have the front bushes, drop links etc checked.


Could worn front shockers cause this ? as the rears have been replace but not the fronts and they look quiet rusty (original sti red front struts) and the car is now 93000 miles.


Regards Ian

i would go out and give the brakes a bit of a beasting and see how they are it could be a build up on material that needs rubbing off

Are your discs grooved??

How were the new braked bed in ?
What technique did you use to ?
