I have a problem. My truck is leaking brake fluid in 3 locations, the MC, and from both sides on the rear axle. I have been using this truck to haul off debris from a house I took down. This last time as I was getting ready to take a load to the dump, I checked the brakes, the pedal went to the floor with no resistance. I checked the fluid and the reservoir was empty so I filled it up and tried pumping the pedal a bit, but nothing changed. I saw that the level went down a bit so I added some more fluid and gave the pedal some more pumps. This time the pedal started to feel just a smidge more firm but then quit coming back up. I traced down all the lines and noticed the three leaks, the MC leak is slow compared to the rear (drive) axle. Both sides were dripping pretty good. I assume the wheel cylinders need replaced. I have never worked on a truck this big before and a buddy tried to tell me that it would be a big job and that I probably shouldn't tackle it myself and should pay someone else to do it. I like to do my own work, what's the hardest part of this job? What are your thoughts/advice?
