Thread: Brake Plumbing questions

Tweet

I'm getting ready to run my brake lines and it's my first time ever doing this so I want to make sure I get it right. I have 49-54 chevy calipers from Speedway and an '86 Ford 9" rear drum. Here's what I have so far:

Front:
Master cylinder-2psi RPV-T connection-through frame fitting- flex line-caliper.

Rear:
Master Cylinder-pressure brake switch-10psi RPV-APV-flex line-T connection-wheel cylinders.

Hopefully this is right so far.

For the hard lines do I use 1/4" out until the final T fitting before the wheel cylinders then go 3/16" from there?

Any input is helpful,
Thanks,
Sean

1/4" for front, 3/16 for rear... ( is how my 64 C10 was plumbed )
