I literally quit. Like I have thrown every god damn trick I can at this thing short of lighter fluid and a match. So here it is.
2003 Escalade, 270k miles or something like that and we just finally replaced one of the stock calipers. It was nice, came from GM with a new bracket, hardware and caliper. Thing goes on, we bleed it and its great... except coming to a stop it chirps like a school bus.
So I pull it back apart and find the lower caliper slide is stuck in the bracket. Cool. I lubed it up bored the hole to fix the casting flash and it worked mint for about 20 miles. Now it has a cyclic whirling noise equivalent to a squeaky door that never stops squeaking. So I swap the old bracket on. Works okay for about 20 miles again and then is non stop after that.
At this point I'm pulling out my hair. Dust shields are gone, e-brake removed (Cable snapped years ago), and there is so much grease back there I don't think the brake is actually doing anything... So I am at a roadblock, is the new caliper sticking? Is there still air in the line or could it be an abs issue? (this has the 4 sensor 4 line system on it because of the AWD so...) Does anyone have any other suggestions before I torch the thing. Also, how freely are the slides supposed to move. Are they free floating or are they supposed to have some resistance. I cleaned them off and lubed them with a mixture of caliper grease and ATF only because the caliper grease by itself is like silly putty.
Any help is much appreciated.
