Paul372 Posted July 13, 2009 Share Posted July 13, 2009 hi my jap spec brakes on my supe are juddering and jerking what would cause this, i have newish endless pads and 3g groved discs from envy and goodridge braided hoses, could it be that the discs have wraped Quote Link to comment Share on other sites More sharing options...
supspower Posted July 13, 2009 Share Posted July 13, 2009 That would be my first guess, id get the discs looked at. How long have you had the discs? Quote Link to comment Share on other sites More sharing options...
jacko Posted July 13, 2009 Share Posted July 13, 2009 usually a sign of warped discs Quote Link to comment Share on other sites More sharing options...
movistar Posted July 13, 2009 Share Posted July 13, 2009 you have not said how it is vibrating?? through the car under heavy braking...will be rears!or felt through the steering wheel under normal to heavy braking, then it will be the front! Would be an idea to check for the cause too...sticking calipers or slides, if you take it for a spirited drive with some nice heavy braking, to get them nice and hot you might source it by jacking one wheel up at a time right after this...give each wheel a spin and check for binding or a disc much darker than the rest...or something else which is called fishtailing these are lines running across a disc and look for hot spots(high spot areas)...these can all cause brake judder, please note though sometimes these are on the inside of the brake disc and can not be seen from the outside through the wheel. better still if you have a friendly mot mate get him to run it on the rollers to check for brake imbalance. If not a dti gauge will also show it up, but you really have to know what your looking for when doing that... hope this helps a little and good luck :-) Quote Link to comment Share on other sites More sharing options...
Paul372 Posted July 13, 2009 Author Share Posted July 13, 2009 i can feel it through the steering wheel and the discs and pads are only about 6 months old, being uprated discs i would throught they wouldn't wrap Quote Link to comment Share on other sites More sharing options...
supspower Posted July 13, 2009 Share Posted July 13, 2009 It could possible be a worn wheel bearing sometimes this causes vibrating when braking and you would feel it through the steering wheel. Jack the car up and see if theres any play in the wheel by trying to tilt it and wobble it side to side. Easy job to do to find out and least you can rule that out.

Paul372 Posted July 13, 2009 Author Share Posted July 13, 2009 no its not wheel bearing theres no movement in the wheels and it only passed its m.o.t a couple of weeks ago, i think i wll have to take the discs off and have them skimed, i think its defo wraped discs Quote Link to comment Share on other sites More sharing options...

Paul372 Posted July 19, 2009 Author Share Posted July 19, 2009 just been driving the supe and you feel the juddering more through the brake pedal than the steering wheel, could these be the fronts Quote Link to comment Share on other sites More sharing options...
