Thinking of buying a set of swing type pedals from a fellow H.A.M.B that utilize a 60-62 chev/gmc truck dual clutch/brake master cylinder. Does anyone know if this master cylinder will run front disc brakes? My 31 ford highboy on 32 rails is setup with 70 camaro front disc and ford 9" rear with shoes.
Yes it will work ,but the safety nazis will be all over you for not running a dual cylinder. The MC is 1-1/8 bore which may give a bit harder pedal ,cure that by having at least 6-1 pedal ratio. I've used those cylinders on many of my builds over the last 40 years.
The original truck swing pedals are opposite, compared to aftermarket pedals. In other words, on the Chevy truck master, the clutch bore is on the p***enger side. Why this matters, is that if you use aftermarket pedals, you will end up with the stock brake residual valve in the driver side bore, which is now the clutch bore. It needs to come out. I believe most guys with disc front/drum rear, use an inline valve.
I am thinking of using this MC too. What I want to do is use it as all brake cylinder one reservoir for front brakes the other rear brakes. My thought is to have a bar welded to the brake pedal to connect both clevis rods to a single pedal. The car will have disc brakes on all fours. Anyone else ever tried this before? Your wisdom on this would be great! Joe
Yes, I have seen it talked about on hamb. They use what was called a "balance bar", not a welded bar. The balance bar has the pedal mounted to the center of it with a clevis, and each end of the bar goes to each bore with an adjustable pushrod. The bar gets pushed in the center, but can't be a welded joint in the center. It needs to have a pin to rotate on, so both bores get equal foot pressure, and that also allows one bore piston to travel less or more than the other, due to differences in the front brakes compared to rear brakes.
