Master cylinder
What master cylinder is commonly used with a juice brake conversion? My 37 has 40 hubs and I think a ford (mustang?) dual reservoir master cylinder.. I have blead and adjusted them twice now and still have a low pedal.. It has residual valves on both lines..Thinking maybe the bore is to small.. I sure would appreciate some advice..
Thanks in advance..

Re: Master cylinder
67 mustang is commonly used. There are two types, disc/drum and drum/drum. The disc/drum has different size resvoir, the durm/drum are equal. Make sure the shoes are adjusted properly and bleed them starting with the furthest wheel cylinder. Sometimes it takes a couple of tries to get all the air out.

Re: Master cylinder
Thanks.. Mine is a disc/drum type. Any idea if there is a difference in the bore size? I would think the disc brake cylinder would have a larger bore?? I have blead probably a quart of fluid through it and adjusted them twice... Still... Low pedal..

Re: Master cylinder
In my opinion the mustang master cylinder is to small a bore, it's a good chunk smaller than a stock 40 type master cylinder.
I use the stock 40, single circuit I know but it works good. Martin. |

My 33 has great brakes with a stock 39 type cylinder, and 39 pedal box. The 1-1/16" dual cylinder I used was for a mid 70s E250 van. It's massive compared to the mustang unit, which is a downside. Mart. |
