Brake Pad Overhang

[writeoff]

Hi All,

I recently ordered a Stage 1 brake upgrade kit from Unique AutoSports for my R32 GTR (RRP $795). The kit consists of 324mm R33 GTR dba 4000 series rotors , callper adapters, cap bolts, and shnoor washers (what the hell does shnoor mean?).

It was only after ordering and paying for this kit that I've heard of brake pad overhang problems. I contacted Steve from dba to ask about this and he responded:

"A caliper is made to match a certain radius of the disc. When you raise a caliper by means of a bracket it changes the working radius of the caliper and sometimes the pad will hang over the O.D of the disc in the middle of the pad on the top edge. It can cause issues with noise and additional stress on the edge of the disc. I'm sure you can modify the pad if it happens."

Has anyone else experienced this problem , and if so, how difficult was it to modify the pad, and did this solve the problem?

Hi, simple to fix, I haven't used the UAS kit but I have done plenty of rotor size upgrades over the years. Simply cut around 2mm from the top (radius) of the pad material with a hacksaw. Takes about 1 minute per pad.

The trick is to get the pad and lay it on the rotor so that the outside of pad radius lines up with the rotor. You will find that the pads is a tighter radius, so you can mark it with a pencil and then trim it with a hacksaw. You can also file/emery it, but that makes a dusty mess.

UAS should really sell the kit with pads that have a larger (outer) radius to suite the larger radius rotors.

cheers
