Hey guys

I have a 1990 Honda Civic DX 4 door. It has rear drum brakes right now. I have sourced the front and rear brakes from a wrecked 1990 Acura Integra.

For the rear discs to work on my car I had to also get fromthe Integra the rear traling arms spindles and e-brakes cables. I also took the sway bar as well

Anyways my question is what I should use for a master cylinder to make these brakes behave correctly. I want the front/rear brake bias to be correct. I already removed the proportioning valve from the Integra as I feel it is set up differently than the Civic.

As for the master cylinder the one from the Integra will not bolt onto the Civic b/c the bolt holes are inverted and do not line up. The Integra and Civic MCs look the same at first glance. They both have a 15/16 bore. However the Integra MC has a larger fluid reservoir and cap than the Civic.

Questions:

1. Is the proportioning valve between the Civic and the Integra?

2. Should I get a MC from a 1988-1991 Civic Si or CRX Si...anything with rear disc brakes?

Thanks for your help
