When you finish that I have this LeMans down here...

The rate I'm going we will be well into the "senior citizen" category before that would happen.

My daily driver 2002 Chevy Silverado 2500HD needed new rear rotors and pads like yesterday. It's been pitch black dark out a while now, I took these pics when I started. Coyotes are howling nearby. The one rotor got so worn that orange and silver shavings are stuck to one of my wheels, haven’t tried cleaning them off yet. The lower T55 bolt holding the caliper on is rusted in. I used lots of heat and penetrating fluid and muscle over the course of an hour. No luck. Will continue tomorrow.

Before going further, use a prybar and see if you can push the pistons in. If not, caliper time.
If so, see if it moves on the pins.
If not, caliper time.
If replacing the caliper, no need to worry about the t55 pins that won't come out.

I find that on a vehicle of that age, the surfaces of the caliper frame where the pads ride are nearly always deformed from wear and rust, causing the pads to stick. I hone the surfaces flat with a stone on an air grinder and apply high temp anti-seize compound.

Thanks for the advice. I’m aiming to re-use the caliper.

Thank you.

Bro, be prepared to need calipers! My Silverado, which has lived a little nicer life, and live in a little easier climate , and all the bolts came off easily, still the caliber for the rear

I agree with @redline4 if the piston doesn't go back in you need a caliper whether you were planning on it or not. Where just one side is grinding chances are you could need a caliper. Also @FergusonTO35 is correct make sure the pads move in the brackets they rust up and stick you will want to clean them and put some grease on them

 

[Bigmac]

And mine did all of that and were still bad!, they got a touch sticky, even though everything was free! The pins will sometimes wear a touch misaligned, once you reset them, they won’t slide out the same as they did the first time! Lol

A neighbor told me a story from back when he was in his late teens along those lines. He and his dad took his truck up to hunting camp and a buddy tagged along in his own rig. They get to camp and his dad hops out of the truck, starts stretching, and stops to look at something behind the front pass tire. "Your brake line is folded over and pinched off with vice grips!" "Yeah, the hard line tore so I pinched it shut until I get a new one" His dad then looks towards the back end of the truck. "You've got a set of vice grips pinching off the soft line for the rear brakes!!!" "Yeah, one of the rear wheel cylinders failed and I haven't figured out which yet." His dad rode back in the buddy's truck.

Ouch! Have you done an autopsy yet?

 

[Woodslasher]

Nope, not my truck. I have to wrap up the cruiser engine, do struts and misc front end work on my fusion, struts + motor mounts on a murano, dipstick tube repair on a 7.3 Powerstroker, and mebbe a lift on the cruiser in this coming week as well as possibly aiding in swapping out that rear end for a good used unit (depending on how things go) so the autopsy will wait.

Somebody else did an autopsy today (no pics), limited slip unit bolts backed out, carnage occurred. I'm in talks with a friend and the owner to see if it'll be a rebuild or replace scenario.

Good for you. Being able to do the work yourself easily saved you at least $1000.

So I’m pretty sure the rubbers here need to be good and keep ice/snow/junk out. One came slightly deformed on the unit. I put it together anyways and played with it a bit. Of course not on the truck yet. Wondering if I have to go back to Oreilys tomorrow for an exchange or if this will work? Really wanted to get the thing put back together tonight yet. One rubber is way better and more balloon like than the other as you can see. Ideas?
