Brake fluid loss....it disappears
OK I changed my MC to a 88-91 prelude one (it was a reman part) about 2 months ago. Now its twice that I have looked under my hood to notice that the brake fluid reservoir was down to the min. line. Each time I have filled it up to the max and it seems to be disappearing. I bled the lines 3 times right after the MC swap and also bled the MC. Do I need to rebleed now after driving a few hundred miles? It dosent appear that any fluid is leaking from under the MC where it meets the booster and none of the lines appear to be leaking either. What do you guys think?

cap seems fine and bleed valves seem ok. I guess maybe it was just low after bleeding a few times?? Any other ideas?

yeah, if the pedal doesn't always feel so hot, it could be leaking out the back of the MC into the brake booster - then you'd have no visible leak anywhere.

The pedal feels really good but every now and then while driving and then braking it feels better to pump the pedal one time and it gets rock hard again. < HAHa i know that sounds perverted but its the only way to describe it

replace brake booster hose w/ clear tubing, let the engine idle and have someone pump the pedal while you watch the hose. If brake fluid is leaking into the booster, you may see it get sucked into the engine through the booster hose.

or prop valve., one of the seals could be shot on that, causing it to leak into master clyinder.
You could just upgrade to a Integra booster and prop valve for some extra braking
Just make sure thats where its leaking from. take a Q tip and rub the inside of the vacume line. If you pull it out and there brake fluid on it then something is leaking in that line, wich means something is leaking into the booster
