tomdotc Posted July 5, 2014 Share Posted July 5, 2014 I've got some brake judder and feels as if it's coming from the rear. I can feel heavy vibration through the steering wheel and happens anywhere from 30+ mph. I had to change my front discs and pads anyway so I changed them over for black diamond ones and still had the same issue. Today I have changed the rears over as well for black diamond and still getting the same. I've gone through previous topics and unsure if some of it applies to me as I have already replaced discs and pads. It happens when in gear and when in neutral and also happens when the clutch is held down. I'm thinking of taking it to Sly at Kaizer motors but wanting to get other peoples opinions/thoughts on the issue and see what I can do before I take it to Sly. Can anyone offer advice on what this could be? Quote Link to comment Share on other sites More sharing options...
Lexx Posted July 5, 2014 Share Posted July 5, 2014 Just to clarify this happens ONLY when you are braking? Quote Link to comment Share on other sites More sharing options...

Commander Posted July 5, 2014 Share Posted July 5, 2014 What state are your disks and pads in? Anything too worn? Lips on disks? Any pistons ceased? Any uneven wear? Quote Link to comment Share on other sites More sharing options...
tomdotc Posted July 5, 2014 Author Share Posted July 5, 2014 It's all brand new (front & back) Quote Link to comment Share on other sites More sharing options...

ZMANALEX Posted July 5, 2014 Share Posted July 5, 2014 If the judder is coming through the steering wheel then it will be fronts and if it is brake related then you will probably have a DTV issue. Alex. Quote Link to comment Share on other sites More sharing options...
Rocky4510 Posted July 5, 2014 Share Posted July 5, 2014 Mine judders a little bit too when breaking at high speeds. It was extremely bad, then I change my discs and pads and now it's not bad, but it still does it. What's a DTV Alex?

tomdotc Posted July 5, 2014 Author Share Posted July 5, 2014 Would DTV even occur with new discs? Thought that only happened over a period of time/use. Quote Link to comment Share on other sites More sharing options...
Ebized Posted July 5, 2014 Share Posted July 5, 2014 Would DTV even occur with new discs? Thought that only happened over a period of time/use. That change seemed to been missed by those mentioning DTV, noting you said the issue remained after changing discs. That suggested to me something else was amiss. Hence why I thought your idea to visit a well respected ex HPC Nissan Technician was a good idea, Quote Link to comment Share on other sites More sharing options...
roscopervis Posted July 7, 2014 Share Posted July 7, 2014 There's probably some rust or other crud on the mating surface between the disc and the hub which is amplifying the imbalance when braking. Discs these days never warp but pad deposits can build up causing dtv issues. If pad deposits are suspected, the posted link and the bedding in procedure should be followed. If that doesn't work, take off the disc to clean the hub surfaces. Quote Link to comment Share on other sites More sharing options...
Martinjj Posted July 7, 2014 Share Posted July 7, 2014 (edited) A good tool to use when changing your own discs is a "Dial Test Indicator" (DTI for short) its a relatively inexpensive tool at around £20 including the stand, really simple to use, once your new discs are fitted you will be able to see high points caused by an uneven mating surface by spinning the disc while the DTI plunger is touching against it. This video is pretty self explanatory of what to do, 1st few seconds are too bright to read DTI , but after that you get to see it properly.

Ledsandwich Posted July 8, 2014 Share Posted July 8, 2014 It may be worth checking the condition of your ball joints, tension rods and top mounts as they can also cause the steroid wheel to judder under braking. Aaron Quote Link to comment Share on other sites More sharing options...

If that doesn't work, take off the disc to clean the hub surfaces. This ^ If it the same from both sets of discs. The smallest bit of crud on the hub will unbalance a disc. Take them off and thoroughly clean the mating surfaces. Quote Link to comment Share on other sites More sharing options...
tomdotc Posted July 18, 2014 Author Share Posted July 18, 2014 (edited) Problem fixed. Turns out it was a build up of rust / crud on the hub. Sly @ Kaizer Motors fitted new discs and pads as well, did usual bedding in and already notice a massive difference in braking now and no more judder! Sly showed me before and after pictures of the hubs and the difference is amazing, they look brand new now Sly if you read this, just want to thank you once again for doing a top job on this and managing to fit me in despite a busy schedule.

zxrob Posted July 23, 2014 Share Posted July 23, 2014 Tagging on to this topic, I noticed tonight that I have a slight judder through the steering wheel and through the brake pedal now. I have newish dics and pads (less than 1000 miles) tyres are virtually new, all balanced and 4 wheel alignment, I recently had the front wheels off to clean areas around the brake pipes, I torqued them back up properly and re torqued again after about 50 miles. Also, it feels as if the car moves very slight to the left or right when braking hard, what could this be, cheers Rob Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted July 23, 2014 Share Posted July 23, 2014 All the answers are in this topic and as the OP was effected by DTV then I would suspect that you have similar issues and the only fix is a good clean up and fit new pads and rotors. Have a read through all the previous posts in this thread. to get an idea of this issue. Alex. Quote Link to comment Share on other sites More sharing options...
