[quote=”celticbhoy” post=52502]It’d be the master cylinder’s secondary cup seal on the primary piston that’s leaking onto the booster. The booster connects to the master cylinder by a pushrod. If you see fluid on the booster shell or even the appearance of the boosters paint eaten away then that’s the issue. Did you thoroughly check all of the line fittings going into the calipers or wheel cylinders? Really hope for your sake it’s not the ABS module.[/quote]
Yes we went through everything and there is no sign of leaks anywhere near or around the calipers. My car doesn’t have ABS.
[quote=”EricTheCarGuy” post=52492]I didn’t think you’d notice anything by removing the vacuum hose for that very reason. Personally, I’d unbolt the master from the booster and see if it’s leaking there. You don’t have to disconnect the brake lines, you can just unbolt the master and pull it forward to have a look. It wouldn’t be the booster that’s leaking anyway, it would be the master cylinder leaking INTO the booster. If it’s not leaking there it may be leaking into the ABS. I have seen some systems do this when a valve in the ABS goes bad. Keep us posted.[/quote]
We did remove the brake master and there was no signs of leaks there. We replaced the master cylinder and it still seems to be leaking but far less than before. It’s been well over a week and I’ve lost the smallest amount of fluid. Barely even noticeable. Car doesn’t have ABS.

Not sure what happened but we looked for leaks and found some places that might be the culprit but because it’s the middle of winter here we weren’t sure as the car’s undercarriage is covered in ice and slush/snow. So I let the car sit over night in a heated garage and we checked again (this was a few days later after we checked the first time) and we noticed no leaks after pressing the brakes for a long period of time, over and over. We bled the system for a second time and the brake pedal feels back to stock and we haven’t noticed any leaks…

Hey, everyone, little update. I changed the master and slave cylinders and the clutch works better than it ever has. The clutch use to engage closer to the floor now it engages closer to the top. I was told it’s supposed to be closer to the top. So I’m assuming these needed to be replaced ever since I bought the car. The clutch pedal still has enough freeplay.

That says cable operated while mine is hydraulic. But how would the pedal just decide to adjust itself one morning and act like that.

Thanks everyone. Unfortunately I can’t look into the brake master because what connects the vacuum hose is a 90 degree bend. My girlfriends dad who’s a heavy duty mech. also said that was most likely the problem and to dip something into the booster and see if it’s wet.
Will report back with results.

Well there is no fluid anywhere on the lines according to the mechanic. It’s near impossible to see the hardlines against the firewall because they are behind the engine and covered with everything. I’d have to remove the engine to get to them. All the fittings and rubber hoses arent leaking anything.
