Rear Brakes

[onzlo]

Hi can some one please give me the size dimensions of the rear disks on a 260zt-t. I want to get grooved and drilled brakes, I believe the size is 332mm but wanted the thickness and stud spacing if possible. Or the info on callipers like what car they are from.

you simply wont find any as they have the handbrake in them. stick with the originals

agh ok then thank you will do so then. as it goes it failed the mot on hand brake due to brakes. Thanks Peter

mine has failed in the past on the handbrake. best is to remove the disks, clean the shoes up and rough the inside of the disks up and have it adjusted properly

Another option is to have the discs skimmed. I had this done to get mine through the MOT (also failed on handbrake).

At the weekend I refurbed my rear discs by grinding off the wear lip with a belt sander and getting rid of the outer rust, I then sprayed the bits that rust with heat proof spray, they now look as good as new, I measured my new set which were 28mm and my existing are 26mm ( I cannot find a wear limit anywhere on any 260 literature ? )
I also measured the overall diameter of the shoes in various place and compared this with the measurements 2 years ago, I have found the shoe adjustment has not changed much at all in 10000 miles but the cables have stretched, to sort it I just tightened up the nut at the front ( which has a spacer behind and the handbrake is fantastic, when you fit a spacer remember to tape it up otherwise when you let the handbrake off it can rattle, just shows the cables do stretch
in a short time, and my car is only used weekends/ holidays .

Skimming the disc will not affect the handbrake.

Give them a good clean and adjustment and it should past the MOT.
