Rear brake not wearing outside of the rotor

[spaghettihoes]

Hey all,

I changed out my brakes for project mu clubsports and ran into some brake judder on the track. I flex honed the rotors, lightly sanded the pads and rebed the pads.

One of my rears (outside pad) seems to not be contacting the outer edge of the rotor although the other pads (including inner on the same caliper) seem to be fine. I added some permatex brake lube previously on the pins and back of the pads but I think it got cooked on track so I took off most of it when I redid the pads post track event and installed them without any lubrication.

Is this an issue with the sliding rear pins? Maybe the pad ears need to be lubricated? The braking feels fine even at threshold braking.

Do you have the pads on the right sides? They have little dimples and are side centric as they align differently in the carrier.

I did, the ones with the center dimples are on the outside. The ones without them I put on the inside as that's where the piston hits it.

Yea that is correct. I would say brake harder if you haven't yet. It takes some brake force for the rears to fully clamp.

I did about 10 pulls from 40-80 slamming on the brakes but I'll do it some more. The other side seems fine.
