Have been dealing with a leak thats got me stumped. The front resivour is constanly getting low. No leaks or drips noticable on the ground. Calipers and lines are dry. I found a leaking cylinger on the rear, so I replaced it…was certain that was the issue. Rear brake drums are dry now. Fluid was still getting low, figured it must be a leaking master so I replaced it. The issue is still happening…here is what ive found, engine running so power booser has boost. Cap on, sitting in the car pumping pedal repeatidly I see fluid pool up at the back of the master. Not where it mounts to the booster but below the rear of the cap.
So leaking cap?? There is no way all the fluid in the front is leaking from the rear of the cap. The only other thing I can think of is if its pooling in the bottom of he booster, or was leaking before and now the booster is somehow pushing it out?? Really stumped on this. It happens so that I have to fill it every oher week or so. I probably drive it 2 or 3 times a week.
