Howdy, I have a 48 1.5 ton with hydrovac of course. It all works good except the master cylinder is pitted and won't hold fluid even with a hone and rebuild kit. Fluid leaks right out the front. After about 2-3 weeks it's out. It is 1.25 inch bore, .25 inch line, about 2 7/8 inch bolt spacing for mounting. Will the cylinder for the 1 ton truck fit? What master cylinder do I need and where would I get it? I have been adding fluid to my cylinder for 12-15 years and bleeding the brakes every time I want to use the truck. It's time.
