I have a 87 4Runner that underwent a brake job about 9 months ago. The pads, shoes, rotors, one drum, a caliper, a slave cylinder and the master cylinder were replaced. Each time something was fixed, something else went wrong. After all the repairs, I then lost all pressure in the brakes, so I replaced the replacement Master cylinder and now I have some pressure in the brake pedal. I can stop the vehicle, but it is an eye opening experience in emergency situations. I also have a rattling noise that goes away when I apply the brakes and a click when I apply the brakes. I have bench bled the MC, bled the system 3 times and adjusted the rear drums with out any change. Anything I can check with out pulling each wheel and drum to inspect every part of the system? Any ideas are welcome.

The part I liked best was this bleeding advice- "I use a finger full of grease around the bleeder valve and a 60 cc syringe from the vets office and a bit of vaccum tube to pull a lot of fluid through at a time." -Missoriman

As far as the rattle, might be loose park brake, but I would pull the rear drums and do a visual check. Make sure everything is back the way it should be and moves like it should

Are you bleeding them in the correct order?

I found some of the noise, A loose pitman arm and loose wheel bearings. I was able to repack and torque the bearings to correct numbers thus reducing some of the noise, and now my brakes are not mushy, just softer than I want. No need to pump the brakes to stop.

The book I am using says the the LSPV cannot be bled. Is it as easy as the brakes?
