Clean the corrosion from the caliper bracket behind the shims. Does not take much corrosion to bind the pads. Lube behind the Shims also to help prevent further corrosion.

You're partially right. If you're not properly trained in how to use one, it WOULD be a waste of time for someone to own a Tech 2. +1

Not likely.

The lower right port is labeled in the diagram as REAR input...not front The whole point of my post was to point out that the lower left port that says front input is really the rear master cylinder line and that the right lower port that says rear input is really the front line on the master. The mechanics lable those two ports as right master and left master, in that order. Primary will be for the front brakes and is the front portion of the master cylinder. Secondary is is for the rear brakes and is at the rear of the master cylinder.

Another description: 2000 Tahoe is the same. When looking at the brake pipe port face of the BPMV, the ports are assigned as follows: • Upper Left—Left Front Output • Upper Middle—Right Front Output • Upper Right—Rear Output • Lower Left—Master Cylinder Secondary/Front Input • Lower Right—Master Cylinder Primary/Front Input

When checking G100 Make sure it is mounted to the frame. This ground ( battery to frame ) is often mislocated to the core support if any body work has been done. G110 and several others run through G100.
