Lexus IS200 2002 - Rear brake judder, discs changed #

Posted by Vince Mosley on July 7, 2012, 9:07 am

Year of Manufacture *: 2002

I have this car which has had a history of brake judder, i.e severe judder in the rear under braking.
I have changed the discs 3 times, i always check run out and clean mating surfaces when fitting. I can detect no wear in any bushes or joints. Has anyone else experienced this. I have checked it again this morning and no run out on the discs but it is awfull to drive. Its had new pads, new calipers as well.

Hi Vince,
it used to be common practice to reface new discs on the vehicle on Jap cars. What make of discs and pads are you using?

Hi Andy, they have been Mintex,Blueprint,TRW . I could accept what you say if i had run out on the discs, but there is non, and the thing is we fit hundreds of discs and never get an issue.

Hi

Judder is normally caused by DTV - Disc thickness variation - not run out so check for that.

DTV is normally the result of run out or pad bind. which is why it appears a while after fitting, both of which you appear to have covered.

As said above, disc skimming equipment was standard for Toyota dealers and common practice to correct this fault, I think there preferred equipment was made by a firm known as M.A.D.

I will say that the occasional reoccurring judder issues we have had, have all been successfully fixed by skimming on the vehicle with a MAD tool.

Cheers Aidan

Hi,
I would agree with Aidan, check for DTV then remove the pistons from the calipers check for residue or pitting (check sliders if floating caliper) then find someone with a brake disc lathe MAD or ProCut and have them skimmed on the car

I had a judder from the rear on a Volvo c70 a few years ago that had disks and pads checked the wheel ballance whicch was out and it cured it. may be worth a try?
