>Here on the West Coast many of us GMCers have been happy the following
>Master Cylinder:
>mfg. Wagner
>P/N F79821
>Size 1 1/4" piston
>OEM 1970+ Chevy 1 ton Truck
>Cost $60 new
>Warranty Lifetime (Keep receipt)
>

>Wagner has been on my coach for approximately 9 years w/o any problems.

>Front brakes
> Front Calipers OEM (not over size)
> Brake Pads Carbon Metelic (Performance Friction Co)
> Pad P/N 0524 (about $40)
> New Hoses ????? Long Toronado (2)
>Rear Brakes

> Rear Axle Cyl 15/16" Wagner F51081 OEM Size
>2 sets Brake Shoes Asbestos Only GM #8020290/Delco
>#171-500
> Springs New Sets
>Combination Valve (Brass) GM #25509419

>After total refurbish job, add Brake Guard & see a big stopping
