does any one know what causes brakes to judder.
i have brand new up rated discs and pads all round they are about 3 months old and when i give my car some abuse the judder real bad it shakes the whole car it seems to be getting worse. the car is a 4x4 saff cosworth its got avo coil overs aswel if that is any help

 

bushes track rod steering rack wheel balencing could be lots athings dude

 

maybe the disks are getting to hot and going out of shape a little

 

it had the tracking and wheel balanceing done on it about 6 weeks ago.

 

it only does it under mediem to hard brakeing. if i brake light its fine

 

it would take some serious braking to warp the discs.

i'm having the same problem with my turbo. it shakes to fuck under braking. the discs are new, my tyres are fine and all of the bushes around the front end are fine so i'm now thinking it must be something to do with the steering rack.

is yours only under braking aswell? you'd know if it was your tyre balancing cos it would do it constantly.

 

Look for discs warped, bushes worn.

 

will do

 

track control arm bushes and/or antirollbar mounts worn - has it been polybushed?

you need to do the whole fornt end (whole car preferably) costs about 110 quid for the bushes and about 300 quid for someone with a ramp to fit them.

 

dont forget the drive flanges ... just because you have nice new discs ... dont mean what they are bolted to are straight !!!!!!!!

 

If you can feel it surge through the pedal it's warped disk but if you feel it maily in the steering wheel it's bushings.

 

yer its through the wheel it has not been polybushed

 

mine had taht on my escort, turned out to be warped disks,
go get tehm resurfaced or but newones if there old!
