I am moving the master cylinder on my 53 to the firewall. I am going with booster and master for drum/drum. I noticed that the stock brake lines are really small. Do I need to use larger lines? I will eventually switch to disc on the front down the road. If I need larger lines I will be a to change the front hoses and the tee on the axle, right? How about the wheel cylinder?
3/16" is the standard size for most street vehicles... plenty of fittings and clamps available online... you can buy in rolls or straight sections... most auto parts have various lengths of straight sections flared with male fittings on each end... buy decent flaring and bending tools to avoid leaks and frustration. Here's an article I did on my disc/disc... only difference is adding residual valves where needed... keep in mind this was an article by a rookie, there are lots of guys here that put me in the shade... they will lead you down the right path.
I picked up a power booster from my local hotrod shop but they didn't have a master cylinder. I picked one up from auto parts store listed for 67 C10 Chevy pickup. Is there suppose to be a rod that goes from the booster into the master cylinder? How do I know how long that should be? Where do I pick that up at?
there should have been a rod included with the booster. Mine was 1/4"-20 thread and was too short for my m.c. I used a 1/4" bolt and rounded the end that pushes the mc plunger. You will have to measure the distance you need so the bolt just touches the m.c. plunger when bolted together. If the rod is too short you will run out of pedal before you push the m.c. plunger far enough to actuate the brakes. When you set the rod length make it a little long and as you mount the mc on the booster you will feel the rod against the plunger, Back the rod into the booster just a little till you can just feel the rod making contact and tighten the lock nut... you can feel it better than I can explain it.
