is anyone on here running a DA master cylinder while still running the drum brakes and stock porportioning valve? my DDs stock MC is on its way out and i have a DA one from another car i stripped and i wanted to know if anyone was running a setup like that and had any problems

 

You will have to use the DA brake booster with the DA MC. I am using the 91 EX MC (15/16") on my std hatch, stock prop and drums. Works just fine.

 

cool, thanks its nice to ask a question and actually have it ansewered on here for once

 

You can also use any booster with the same bolt pattern for the master cylinder. I'm using a DA master with a DC booster.

 

This is correct!

It's best to leave your exisiting proportion valve for right now when swapping in the DA master cylinder, & brake booster. When you decide to go rear disc brakes, then you'll want to swap in the Integra 4040 proportion valve.

 

How do you know the MC is going? does your pedal go randomly soft?

 

The brake pedal will sink/wont hold pressure.
