Re: Jeep TSM rear disc brakes
I've learned a lot about those Caddy calipers from experience. This is the third set of pads I've had in them, they've been on 8-9 years. I first bought used ones, I couldn't get the puck screwed back in one of them. Tried taking the arm off and screwing it in that way, don't work, just ratchets. I used it as a core on a rebuilt. Next time, the other one wouldn't screw in, so it got replaced with a rebuilt, I've learned to keep them oiled a little.
This time they both screwed in fine and I was able to adjust the pads up with a crescent wrench on the e-brake lever. Yes, the little nub on the back of the pad is in the CORRECT slot on the puck (another learning experience, I thought I could use any of them when I first put them on, realized only one works). That was the reason for using the crescent on the lever, I had to hold the pad against the puck to keep the nub engaged until I got it adjusted up some. The rotors have been turned and if I don't get the puck adjusted up some, it can turn and move the slot out of alignment with the nub (another learning experience). I can hold pressure on the brake and then cycle the e-brake pedal a few times, but the crescent was there and I was there so … Besides I wanted to make sure the ratchets were working and tightening the pads on the rotors. They were.
It's been this way for years, I almost never use the e-brake. I pump it up a few times to adjust the pads when I think about it, but I've never had an e-brake that would really hold. I suspected cable stretch so I've replaced them too.
This time I only got about half pad wear, they wore at an angle. The leading edge, in forward motion, was worn down until the squealer was sounding, the trailing edge was almost original thickness. I think this was from not remembering to cycle the e-brake pedal often enough.
