Rear driver side has a burning smell coming from the brakes. I'm thinking it's a stuck caliper but i took the wheel off and pushed the piston in with a c clamp and pushed the pedal and it came back out. Did that multiple times... dust shield was rusting away so I just tore it off.. adjusted the E brake as well. Inspected the pads and this what they look like. They have meat left but look like they are "crumbling" a bit at the top. Should i replace???? Going to re grease the slider pins tomorrow afternoon but after that idk what else it would be. Didn't check if anything I did fixed the issue but wanted to get it all done instead of jacking up the car 10 different times part by part lol

 

Replace those pads and the rotors too. Regrease the slider pins and make sure they move, Also replace the boots if they're torn.

 

Holy smokes those look horrible. For sure replace those and inspect everything else back there very closely.

 

Is there a brake pad under the rust somewhere?

fyi, I replaced the rear passenger brake caliper because my old one was sticky. in hindsight.. make sure you bleed the brakes very extensively when you change that caliper. Like, run 1/2 a quart of fluid through it until it is clear as water (almost)...that is, for just that right rear caliper.. More fluid required for the other 3 corners.

And I highly recommend Russell Brake bleeders... Best solution for 1 man bleeding system EVER. (and you don't ever pump up the brakes and blow out the master cylinder.. Just 1 pump, and it squirts 1 time. easy peazy)

Come to think of it.. I NEVER understood why old mechanics always Pump the brake 4 or 5 times to "pump up" the system before the helper opened the valve by the wheel..
I mean, why Pump it up? It doesnt make sense! You dont have to do that! If you had to pump the brake 5 times to get pressure, then Lawsuits will rain down on all the auto manufacturers.. Imagine having to pump the brakes 5 times before you stop! Its so ridiculous. Bozo brain mechanics...You dont have to pump it up. Just 1 Push = 1 Squirt.. nice and easy. And that is how your brakes are suppose to work anyway.. So i have no idea where this idea came from that you have to "pump up" the brakes 4 or 5 times before you get enough pressure and then open the valve by the wheel to get the fluid to come out.. haha Unless you are trying to blow out the master cylinder.. then go ahead and pump until you get a leg cramp. haha crazy!

by the way, I also recommend doing a 2nd bleed after a month or so. Because if the brake caliper is bad or "leaky" then moisture can get into the fluid.. and that is evident by a green tint to the brake fluid. But yuou need to wait a month or so after the first bleeding job, then you can judge if the system is getting moisture in it.
