I CHANGED THE MASTER CYLINDER (http://honda-tech.com/zerothread/1633704#) AND BLEED THE BRAKES (http://honda-tech.com/zerothread/1633704#) ON THE CAR (http://honda-tech.com/zerothread/1633704#). THE BRAKES FELT PERFECT UNTIL I CHANGED THE BOOSTER CHECK VALVE,NOW THE BRAKE PEDAL (http://honda-tech.com/zerothread/1633704#) GOES SLOWLY TO THE FLOOR. DO I NEED TO BLEED THE SYSTEM AGAIN?
THERE IS NO LEAKS ON THE LINES. WHAT ELSE CAN BE WRONG?

if u slowly put pressure on the pedal does it sink slowly but if u slam the pedal does it hold?

if u got any petroleum based product inside the resevior and into the fluid then ur whole brake system is pretty much fucked. petroleum makes the seals swell and get all gummy and so all the seals in the master cylinder, calipers, and wheel cylinders are shot. u have to flush the whole brake system really well and replace all the seals in everything pretty much. even one drop of engine oil or wd40 or anything like that is extremely detrimental to ur braking system

yeah sometimes people will like try to make stuff pretty and spray wd40 on all that stuff to clean it up and make it look good and they just ended up messing up their brakes
