Have disks all around, so shoes are for E-brake only. Exactly how does the "auto adjust" ebrake work, and how do I tell if I have them and if working properly?
Note: no rubber plug inside the brake drum to remove and adjust.

Not sure how the self adjusters work, but according to the Haynes manual, the Parking brake pedal should travel between 9 and 13 clicks as you slowly press on the parking brake pedal. If it tightens up in less than 9 clicks, it is too tight, and if it takes more than 13 clicks to tighten up it is too loose. According to the manual, either one requires a cable adjustment.

I hope this helps. :grinyes:

If you have 4 wheel disc brakes then you are correct in saying the shoes are for the e-brake system only. The only way this would ever wear was if you drove with the e-brake on. If it needs adjustment check to see if a spring has come loose or mayber the cable is stretched or hanging up. To inspect the shoes, remove the rear caliper and rotors.

You have to adjust the cable down by the drivers door - put a small open end on the cable to the rear (threaded rod at cable end) and then turn the adjust nut where it goes into the bracket attached to the front section - if rusted/stuck spray with rust/lube stuff and wait - do not force and break it. Push pedal to determine when correctly adjusted. All 98up like that.

Not always... Inside the rear disc/drum where the horse shoe pads sit, are to adjusters on either side of the spreading mechanism. The horseshoe ends come to either side. Run counter clockwise to spread the horseshoes out more as well. Do this before adjusting the main cable linkage under the door. 9 out of 10 times this will solve the e-brake looseness issue.

Thanks everyone. I have the Haynes manual. Thats why I posted. My Blazer is fully loaded. E-Brake does not click when engaging. It is silent. It does stop where ever I stop pushing on the Ebrake. Guess I'm pulling the rotors to look.

They all click as its a cam type gear with a pin that engages on the drivers side in the cab - something could be in the way of the spring up there - had one on mine after the dash was out that got in the way so had to feel around and move some wires over for it to engage.

Actually, mine doesn't click either but works fine.

This was a fully loaded corporate blazer via the VIN. No clicks. Talked to a brake expert. Said the mechanism was only for initial install. Park a few times with engaging the brake, they will adjust. If pedal continually goes to the floor, then do the cable adjustment.
