looks like one side is wearing a lot more than the other. Whats up with that?

I'm going with caliper rebuild for the win...... Looks like you have one stuck piston

So then, one pad has been dragging all that time??

I have been eyeing some of the shiny stuff on PMBs website...

Perhaps not that one was dragging so much as only one of the two pistons (the not stuck one) was being pressed against the rotor when you applied the brake. How long did this take to happen?

I had the master cylinder changed out a little over 2 years ago and I'm assuming that the vintage car mechanic that did it would have said something then if there was uneven wear at that point, but can't be sure. I'm trying to do all the work myself now so I'll know the car better.

If ya want to do the work yourself, rebuild it. Not that hard. Take that money you were paying some one and buy tools.!! Oh If you clamp that loose piston down in the hole ,you can use the pedal to blow the other out. After you remove the pads. Better than using air and making that piston a bullet! OOOHHH Is that the rear caliper? I see that adjustment nut on the side. That is a little more tricky!!! You want to be VERY careful pulling that apart. Read the manual before you even touch it. There is some adjustment mechanism inside and it is a real BITCH to get back together if it comes apart. Ask me how I know. You want to ADJUST the piston all the way out before you pull it. Just blowing it or pulling it out will make you a very unhappy camper!

Eric can fix you right up.

Your sucky brakes should have really sucked..... 50%

Rebuild videos on pelican and I PMB. Check them out

I could still get it to lock up, but they where not great at all. Looking forward to getting them closer to 100%.

PMB

Yeah, the torn piston boot is the sure sign that crap has gotten into there and seized yer caliper piston... Eric is the man if'n you don't wanna do it yourself...

Yep, Erc sells a nice kit and is usually complete. Also, use his grease gun method to remove the piston. Much safer and tidier too.

Grease gun method?? Please elaborate. I'm certainly open to safer and less messy methods.

go to www.PMBperformance.com, and watch the video. It explains this.

Pull the pad from the one that is stuck. Press the pedal one stroke at a time until you break it loose. The grease gun method involves pumping grease into the caliper through the bleeder or the fluid inlet. You then must split the caliper to get all the grease out.

Yes yes yes PMB Gonna need a couple of those rear caliper rebuild kits. That's a lot of grease to clean up!!
