I'm in the middle of a project on my 03 Blazer. Replacing rear axle seals, rear brake backing plates, parking brake shoes/hardware, rotors, calipers and pads. I'm just about done, but I'm having issues with the parking brake. I have them adjusted down as far as they will go, but they're still dragging/sticking on the rotor. Especially if it's rotated in reverse. Also, the clip that holds the parking brake shoe down is tight, but the shoe is still loose. I'm guessing this movement might have something to do with my issue? Not sure. Any advice here?

 

I say you found the problem; the loose brake shoe. Now why the shoe is loose needs to be sorted-out. Does this clip need replaced? Is the hole the clip goes into too large? How about the brake shoe itself?
Compare left and right sides, what is different between them?

 

When I say loose, I mean the shoes can be moved side to side. This is the case on both sides. So I wasn't sure if that was normal or not. It's hard to tell if the shoes are positioned correctly because of this movement. When I compared the old shoes/hardware to the new ones, they seem identical.

Well I guess the shoe movement that I showed in that video is normal. I made sure the shoes were centered, and when I put things back together everything was normal. The parking brake works now as it should, and all my repairs were successful.

 

That much movement seems a little excessive, but I didn't really crank on mine that hard attempting to move them like that lol. That little bracket with the single bolt simply holds the shoe in place, but the rotor surrounding it is really what keeps it in place.

But if you got it all sorted out and working properly, good job!

Most people don't bother when the parking brake goes out on their automatic trans vehicle. Personally, I use mine every time I park. And it's nice knowing that it works if I ever actually need to use it as an emergency brake!

One thing I don't mess around with when it comes to my vehicles operations is brakes...

 

Well it did take some effort to make them move like that. I was just trying to figure out what was making the shoe rub the inside of the rotor like that. Maybe I just didn't have it in the centered correctly. Yeah, the parking brake didn't work at all, so I figured it would be a good idea to fix them for those times when I park on hills. The project fixed four different issues: bad parking brake, rotted backing plates, worn out pads, and leaking axle seals. If anyone else out there needs some guidance for this project, a video from South Main Auto helped a lot
