i am looking for a good rebuildable master cylinder for a 62 F-85. it has to be from a power brake car. the power brake cars had a 1 1/8 bore. mine has some pitting at the very back that is allowing brake fluid to drip at a very slow amount.

 

A Power Brake Master Cylinder is going to be very tough to find NEW -- I don't have 1 -- I might be able to find you one or I may have the kit -- the biggest problem was that 98% + of these cars were manual brakes, of course!!
I do have the wheel cylinders, brake hoses, wheel bearings & seals, brake cables, and brake drums for this car !!!!!!!
Call me on the master & / or kit --- Craig -- 516 - 485 - 1935............

 

i located a kit. he told me it is the right one and i sure hope it is. the other problem is that the aluminum spacer inside mine is bad. i hope the kit has the spacer in it. i honed out my master cylinder but there is a very slight pit left. i had 3 people so far tell me it will be OK with new seals but if i can find one i want to do that. i fear that all the others will have some pitting also. rockauto had a kit i ordered but they came back and side it was no longer available. i took that part number and found one on eBay.
