Thread: 1951 Chevy M/C

We had master cylinders like that on the old trucks . We would back bleed them . Remove the master cylinder top and start with the right rear bleeder . We had a small hand pump on a one gal can . We used a vac hose on the end of the pump . This was the only way we could get a full brake pedal .

I built an adapter to put a standard air hose fitting on the M/C lid, then put 10# of pressure to it. open the bleeders one at a time till no bubbles come. You have to keep checking the fluid level, but it's less messy than the regular pressure bleeders when you're working inside the car.

tango,
Your the only other person I know that does them that way, I have a power bleeder that I made from a old VW washer bottle, it works great, But I have to bleed my trike, pushing the fluid back into the MC or it will Not get the air out.
It works great on all cars that way, just don't over flow the MC.
