Thread: Brake Proportioning Valve.

Tweet

Ok now I am confused, I have never bleed a brake proportioning valve.
I already sent off for the replacement valve since they don't make the one for my truck anymore.
Atleast that is what I was told, I found out that a couple of the tube nuts are to big on the valve I have now
and will not fit the new valve. I explained to the tech exactly what I had and he said this would fit.
HE! HE! HE! Sure it will, after I change everything else, rebend all the brake lines, and double flare everything.
These guys are getting as bad as some of the Design engineers!!!

Kurt..........I have a Wilwood PV inline on my car and the fittings are 1/8" NPT and 3/16" line.There is nothing new you have to know if you have a proportioning valve in the system when it comes to bleeding .
I have a PV inline about midway going to the rear lines. I made a mark on the knob and counted how many turns to open and close,then opened it half way. There's nothing else to do except get it plumbed in and fittings tight. You make the adjustments after the brakes are bled and the car is running. You adjust so the fronts grab sooner than the rears.
There can be some different size lines coming from the master cyl. which can throw you off. I have seen 3/16" line and 1/4" line coming from one or the other at the MC.
Usually the larger line is for the disc barkes as they need more volume than drums. The front bowl on the MC is the rear brakes so you know which line is which.
