Cool.

Even with after market ones or just the calipers that where stock?

 

The caliper is aluminum, the piston is steel, brake fluid is hygroscopic, (attracts moisture) perfect combination for corrosion, and the pistons seize to the caliper bore. Always replace the calipers, pads, caliper brackets and rotors when serviceing the brakes. If you don't, you end up with what you just had

 

My caliper's aren't aluminum!
Took sliders apart and used a wire brush on a drill press to get rid of crap on slider's, lubed everything up before putting back together, never took piston's out.
Put boot's back on and everything back together. No problem's with brakes since.

 

The brackets are cast iron but the OEM calipers on 98 & newer are cast aluminum.

 

I forgot to ask if there was a warranty. I wonder if im going to have to replace the new ones, probably...

 

I change my rear brake pads at 99,000 miles. Why, they had 99,000 miles on them, they look brand new, no kidding, a little wear, not much. Still have them for the non-believers.. And yes they were working...Change my front at 55,000 they look brand new also...I heard that the OEM brakes they put on the Blazers were hard brakes and the best after changing them they will wear faster. At 56,000 on my front now, they feel like they need to be change...brake pedal goes down more...

 

Ah! gotcha. But while I'm here, took back pass side apart lubed the sliders again and through the e-brake in the trash with the other one. Darn this thing rolls good now!

 

seems this is a problem on these. I pulled the rears off on the weekend , and upon attempting to push the pistons back they jammed. (mongrel to get out too) Local brake shop machined up some nice new steel pistons, replaced the seals, and all is real good.
