Okay, 2001 Blazer Xtreme(2wd)

Now that that's out of the way, lol, I am having an issue with my rear brakes.

I noticed when I came home after some errands a burning smell. I found it to be coming from the left rear rotor.

So at work I replaced the rear pads and rotors, compressed the pistons, pumped the brakes, and took it for a test spin. The truck would slow down quickly. Rear brakes were VERY hot so they were definitely dragging.

So I took it back apart, compressed the pistons again, bleed the brakes... The left rear was still tough to spin, while the right rear was pretty much free.

Took the caliper off the left, and the rotor spins free, so it isn't the Parking brake.

So, now I'm wondering exactly what to do next.
Maybe new brake line, and if that doesn't work, a new caliper?
Also, would emptying, and spraying out the caliper with brake parts cleaner be worth a shot?

*EDIT* Okay, so a friend of mine told me the seal around the piston in the caliper went bad. So, I guess I have to buy a new caliper.

 

 

Okay, replaced the left caliper, bled rear brakes, Now the right is sticking. Took the right rear apart, greased it up, compressed the piston, started truck up, both spun. Good. Shut the truck off, put it in the "On" position, and in neutral, and the right side drags again. Started it up, right still dragging. Okay, I guess I need a right rear caliper now... Any suggestions.

*EDIT*
okay, I went ahead and bought a new right rear caliper, and went through the whole greasing, bleeding and testing again.
And it's finally fixed!
No thanks to all who didn't help . Just kidding, I know everyone has a life. I am posting from work as is, lol.
Just glad to have this fixed. Now I noticed I need front brakes. oh well. The work never really ends...

 

i work at napa and i hear this all the time, your gonna need to replace that caliper, keep an eye on the fronts also, especially if the rears are going

 

Glad you have it fixed.
