I was trying to get my Tahoe to hold on a fairly steep hill and SQUASHED the parking brake on. As I stepped down on the pedal it popped and slammed to the floor. No more parking brake at all.
I looked at the cables figuring I had popped the end off one. Nope. All good. I just forgot about it for a while.
Now I find myself with enough time to check things out. I pulled the right rear wheel because I remembered I had a leaking axle seal there. Things were all gooey back there as I expected. That's likely why I had to step on the pedal so hard to make it hold.
I can't really see anything wrong to cause the parking brake to fail completely. The pedal goes through full travel with no resistance though it does tell me the brake is on when it isn't pulled all the way up by hand.
My rear rotors are worn out and the pads are worn unevenly inside vs outside so I'm going to get all the brake parts for both sides. I want standard one piece backing plates since I'm pulling the rear axles to also replace those leaking axle seals. My diff cover is badly rusted as are the bolts.
Oddly I can add a rear diff cover to my order at one site but when I try to get just a gasket for it it wants to know more specifics about my differential. ?? Not for the cover; that was just one choice. Somehow to get a gasket for that I need more information than I know.
What kind of can of worms am I opening here? I see getting to the diff cover means lots of really rusted parts have to be removed. Is it likely the backing plate has failed some way to cause the parking brakes to fail??
