Q: Issue involving spongy brakes after multiple bleeds.

asked by on

I bought this truck from a person who had it on a farm. I had to replace one of the brake lines in order to drive it away, and then I also replaced the booster and another line. I've replaced a caliper and the pads, drums, and rotors. Ive driven the truck about 10 times since I replaced the booster. Recently, the brakes feel spongy and go about halfway to the floor before I get anything out of them. If I pump the brakes I get better stopping power. I have not lost any fluid, and I can't see anything leaking from the master cylinder, lines, calipers or anywhere else I can think of. Im starting to think that the booster that I replaced wasn't a good one. Any help would be great

A: You may have rear brakes out of adjustment....

You may have rear brakes out of adjustment. I’d try to adjust them until you get a light drag on the drums. Check both front calipers to make sure the slides are free and lubed well. Then you should have good brakes. The reason you have to pump them a couple times is to take up slack before the brakes start to grab. If you’d like to get this fixed, consider YourMechanic, as a certified technician can come diagnose your brake system and make the necessary repairs to your vehicle.
