A > screwdriver of the right size will work. The shoes I took off were equal in length. The ones I put on from autozone one was slightly longer than the other. I put the slightly longer one on the back. (On the drivers side it would be the one closest to the rear bumper. It is the one holding the emergency brake lever. My manual said nothign about different sized shoes.). Can anyone tell me if I replaced the master cylinder after gettign the rear brakes in order if I have to have a scan tool to properly bleed the system?

Makes me wonder if the shoes on the other side are /also/ the same length, but are shorter than the ones on the side you're working on. I've seen it before where some (even the pros) make the mistake of mixing up the shoes in that manner. > The ones I put on from > autozone one was slightly longer than the other.

My manual said nothign about different sized shoes.). Normally, the front shoe is the "leading" shoe, and is longer than the rear, or "trailing" shoe. -- Tegger

So by front, you mean the front of the vehicle? On the one side I replaced, the one that is about 1/4 inch longer in the packet I bought went to the back. (also the shoe the parking brake is attached to). WIll this cause problems? SHould I switch this? My manual is not clear on this. It is a 1996 chevy truck.

It is designed to have the rear shoe longer and the front shoe shorter. As you turn the wheel forward the longer shoe rotates until it is stopped by the anchor pin on which it pivots. The front shoe (is the shorter one) will cause the rear shoe to pivot into the drum surface. Most of the force against the drum is applied by the rear shoe being pushed into the drum by the front shoe. -jim > > > -- > Tegger |
