I got my motor in today all bolted in on my home made mounts I finally got done! now I am moving on to the brakes, anyone got any thoughts on what sort of mastercylinder I can get use of? my brakes are going to be stock drums on all 4, but don't want to use the stock master cylinder unless I really have to I've got the master cylinder and pedal****embly from this 75 chevy donor truck but I don't know anything about how it works beings the 75 had disks on the front and drums on the rear
On my 51 F-1, I used a piece of 3/4 inch(Ithink) aluminum to make an adapter for a 67 Mustang MC. Extended the rod. Been 105K miles no problem..........OLDBEET
I just swapped an S10 pedal, booster and master cylinder into a 49 Chevy to get a hanging pedal and firewall mounted master cylinder. If I can do it, anyone can! You'll have to watch for firewall flex, and build a couple of braces to keep it in check, but it's fairly easy. Most 'modern' boosters will accept older dual reservoir master cylinders with equal sized portions for drum brakes. (Depending what you take your pedal****embly from, drum brakes may have been available for that vehicle...like early 70s and late 60s GM cars were offered with drums standard or discs optional...making OEM drum brake masters an easy parts store score!) In general, if you run a booster, it will have four mounting studs that pass through the firewall and into a bracket that holds your brake pedal arm. Do some physical holding of the parts in place to see where they fit and work best, then drill your holes and mount it up. Make your braces, run your hard lines (with propotioning valves and residual valves if needed) and you're good to go!
