It's bad and not letting fluid get to the back discs. My cars a gs .

Does anyone know the brake line size so i can order a adjustable proportion valve from willwood?

What makes you think it is the prop valve. In all my years I do not think I've ever heard of one "going out". IIRC all that is inside is a simple ball valve... That should not really be able to die.
Have you tried taking the line loose at the adjuster and making sure it is not making it through? Also, why get a duper expensive one that you are going to need a pretty expensive tool to dail in. Just buy one from anyone on here junking a MX.

Anyway, I only see 1/8" line prop valves on thier site. So if that is what you are going for then there is not any option anyway. Unless you are just asking so you know if you are going to have to adapt your lines somehow.

I had a engine fire last summer and just now replaced my brake pads and motor on the rear.. it locked up during driving ... when i tried to bleed it at the bleeder no fluid came out.. tried at blseeder and none came . so im guessing its bad....




Autozone has a russell brand in 3/16 and 1/8

I had a recent problem where my rear lines were not bleeding at a high enough pressure(just dribbling out with the brake pedal super stiff), thought it might be the proportioning valve cause it was moving from side to side but the fronts were fine. The whole time the rear calipers acted as if they were seized and wouldnt let go or return fluid through the line very well. Turns out the rubber hoses had collapsed and they were alot cheaper to replace than the proportioning valve(stainless braided lines $60 shipped on ebay, PV was almost $180 from Mazda). OP try removing the rubber portion of the hose from the steel lines and see if flow returns to that point, if so, you need hoses!

I tried that, also tried unhooking front the rear "t" section in middle of rear crossmember.no luck
