Proportioning Valve

Ed Carpenter · 06-13-2007, 04:59 PM

Ok guys another question. Is it best to run a prop valve on my Chevy II. I run a H class car that is around 3000 with me in it. It has wilwood disc up front with drums on the back. I put a new master cylinder(wagner)for a 70 model nova on it 3 months ago and fri night it took a s--- and I had no brakes!!! The fluid was bypassing the seals on the piston in the master cylinder. I have since put a new wilwood unit on it and fixed the problem but a few guys have said I need a port valve or I may trouble again. So Im asking the experts what you think? Thanks.

Yes, you need one, I use the residual pressure valve from wildwood, instead of an adjustable porportioning valve, with the drum brakes in the rear use the 10 lb valve. install it in the rear brake line,
works great for me. $17.99 from Jegs[:-grin-:]
