Re: Pressure bleeding

I'm pretty well positive that he has all new brake parts on the truck just as almost every mechanical part on the truck is new or rebuilt. I don't think that is the issue.

Brake adjustment= critical. on that axle if you don't have adjuster slots in the backing plates or drums you have to adjust the shoes out until you pretty well have to force the drums on over the shoes to have them tight enough. If you don't feel friction they aren't adjusted tight enough. Drum brakes are supposed to have a slight friction against the drum if they are adjusted right.

I'm still thinking that some adjustment isn't correct or some parts are mismatched for the application. Add that this is far from the first setup with aftermarket pedal assembly and tiny booster that I have seen guys with similar issues with.
