Review on ACDelco 171 0930 Original Equipment Parking by Kevin Williams

Recently had a brake overhaul on my 2003 Chevy Trailblazer which involved removing the rear axle to replace a rusted rotor (here a Dorman replacement). Now there is actually no brake shoe adjustment and there is some adjustment of the parking brake lever in the car (see video on You Tube). I don't know why but I had major problems with the e-brake after changing the baseplate and everything else for the first time except for the e-brake pad. In fact there was no wear and tear on the old unit but I replaced the same with this brand new part and everything is fine. The rotor MUST NOT fit snugly against the e-brake shoe as this can prevent the axle from moving freely as it pulls towards the e-brake shoe. The rotor should "slide" over the shoe with little resistance when seated and should come loose easily when tightened. Check the e-brake when the rear wheels are off the ground (properly secure the vehicle!) and make sure the wheels are tight and not moving when the e-brake is engaged. This new shoe, combined with all the other replaced parts, should be the ticket.
