Im wondering if anyone has come across this. The 93 Civic Hatch has a rear disc swap, Integra MC, and stock front brakes. For some reason the proportioning keeps breaking. Its weird because I swear I can't feel it break and start leaking. The pedal feels very stiff, and suddenly release and feel normal. I check the PV the next day and there is freaking fluid. Of course bled the brakes. No one makes a replacement anymore, and if they have one they are $150+.

 

Can you explain what a proportioning valve is?

 

is this the thing your talking about

might not be the exact one for your car but that thing

i think he knows what he needs since they tend to keep breaking... you dont really need a 1" MC if thats whats on it. that gives u less clamping pressure then the 7/8" MC in the si/ex
