warped discs maybe?

[domn8]

Ive got judder in my brake pedal under moderate/hard braking, Ive taken the front wheels off and checked the run out which seems Ok with very very slight rubbing on the drivers side at one point.

Could this be enough to cause the judder? or could it be the rears?

yes doesnt take much to get the judders

bloody annoying though as they are barely worn - 13K at most, is it worth me checking the rears or is it not likely to be them

What discs are they ? Have you tried turning them around 180 degrees ? I've fitted discs in the past that have run out a little bit , when i moved em round 180 degrees they were fine .
Its worth a try , only a 5 min job .

try a series (say 10) of hard stops from about 60mph to 5mph and then take a long drive to let them cool down and see if it clears it, at no point come to a complete stop with your foot on the pedal while they're still hot (if u need to stop completely, brake to about 5mph come off the pedal and use the handbrake to stop the car)

sure sounds like warped discs

Thanks for your ideas, dont want to bin barely worn discs if I dont have to
