Discovered these while trying to find out why scraping scratching noise coming from front brakes, seems like the pads stay against rotor after braking. Already replaced MC, rotors, pads, and calipers. Brake lines were also changed to braid during lift kit install.
Thanks in advance,
Hmm, typically the rotor will wobble just a teeny bit, and that will push the pads away by just a tad so they don't rub.
Those notches look like they are there to keep the pad metal holder from clunking into the caliper... if you have any buddies at a brake shop, ask them. I recall the ZJ had similar notches but don't have pics or FSM.
Do you hear the rubbing with the wheels up in the air, wheels off, turn by hand?
If you very gently push the pads back do they move?
Or is something holding pressure from the master cylinder on them such that they cannot retract?
