I recently changed the control arms, hub and rotor on my crx to larger ones of a DA integra (90-93). i am having problems w/ the brakes still after i bled them. I was wondering if anyone knows if i have to change the master cylinder to that of another car, buy one custom for that type of system or is my master cylinder just shot.
Note: The integra master cylinder wont bolt to the stock crx booster

 

I will help ya out...

Start your car up step on the brakes put constant pressure on it... is it mushy? or fade all the way down to the floor with constant pressure on it? If so you need a new MC. Easy way to tell if your brake booster is okay is to un do the brake vacuum hose to the intake manifold you should hear a suction noise if so it's doing it's job.

Your stock EF MC will be 13/16", correct your brake booster wont accept an integra 90-93 or 94+ MC unless you swap boosters to Integra but I wouldn't If the brake booster is fine and makes that suction noise go down to your local napa or schucks and get a new/rebuilt MC you want a 90-91 Prelude SI Fuel Injected Model. This is a 15/16" MC and bolts right on to your factory EF brake booster. It is the same size as any stock or based 90-01 GS/RS/LS Integra 15/16".

 

exactly........ do that.^

 

uhmmm.. i hope you didn't use ANY of the control arms from the DA... otherwise heres a for you trying to get that thing aligned.

 

True... stock Lower and Upper EF control arms need to be used this is the same for the Rear disc brake swap as well.
