Greetings from Maine,
Today the weather was finally nice enough for the LJ to come out of hibernation. I’ve been working on the rig all winter, and among other things, I changed out the wheels, tires, and brakes.
Everything was fine until I started the Black Magic break-in procedure. I've completed this procedure successfully on other jeeps, but this time was different. I started hearing a rhythmic grinding noise from the rear of the jeep after the second braking iteration. I aborted and limped about 500 yds back to my house. When I took the rear driver-side wheel off, this is what I saw:
It looks like the caliper is rubbing the wheel. There is a scored ring on the inside of the wheel and there is bare metal on two areas of the caliper. Damage is mostly to the powdercoat, as I can barely catch a fingernail on the edge of the scored ring.
Peeking through the holes in the rear passenger wheel, I see a similar scored ring and no daylight between the wheel and caliper:
Any/all help and insight on this matter would be appreciated!
