well we do need to know front or rear.. i have just discovered an issue with the rear rear rubber belows. last year i did a complete brake job. pads fluid cleaning Etc. on the 1st week of may i noticed a rear /final drive leak; during the investgation i noticed that i had a motor oil leak off the TOP of the block.. i first thought that was odd. during the oil change i noticed a lot of oil all over the lower block. after the oil change and seal repair i lost the rear brakes.
further trouble shooting displayed that the rubber bellows in the rear brakes was fully expanded. hense forth the brake fluid masqurading as motor oil. the brake oil was being pushed overboard by the belows everytime i used the rear brakes. you will see notch on the side of the cup that allows for the belows to move slowly but keep the fluid from spilling out.

I had a seeping rubber hose. I went looking for a used one. A couple people in UK and one for $80. I checked around Seattle and found a brake and clutch shop that makes brake goses. I got the best, metal braided. Cost me $93. The brakes are tight!
