proportioning valve

[jerkyboyxiii]

I installed an SSBC TSB-A114 kit from Summit Racing with zero issues. Summit suggested pro vlv SUM-760183 to finish the project. Ive never messed w a pro vlv. How do I determine which fittings will plumb into my valve to get pressure to my brakes?

How many holes does it have? Some valves just split front and rear and other valves do more.

 

[jerkyboyxiii]

It’s got five. Two for input from the master cyl, two for front brakes, n one for the rear.

The instructions should say where to hook the lines for each part of the system? Is that what you mean? The pressure will be the same as before, as long as your pistons didnt change size in the booster or at the pads/shoes. The only rhing that will make it harder or softer is if you dont have a booster anymore. Than it will be old school

O'no, the booster is still there. ABS is also intact. I merely ditched the drum n shoe setup in favor of a rear disc setup. The instructions speciify, but the OE lines dont thread into the output side of the pro valve.

ohhhhh. i can't help on the sizing. you will have to figure that one out with someone who has done the swap already. sorry

"Features one 1/2-20 in. and one 7/16-24 inlets. Features two 3/8-24 in. and one 9/16-18 in. outlets."

Just ask for the hydraulic adapter tray at NAPA. Fittings 1910/1911 or in that area should be a match.

I bought this at Amazon to adapt a F-350 master to something:

Dorman 490-543.1: 3/16 In. Female to 9/16-18 Male Inverted Flare Dual Brake Line Adapter

if you are not sure of the thread size, it is easier and cheaper just to go get the hydraulics tray from NAPA and match it up. I had a person at a new store tell me they don't carry them. I asked do you mind if I show you were in the store it is and what tray it is. Went and got my adapter.
