There is a possibility that the brake fluid has broken down some or has gotten some water in it. That can make the brakes feel spongy too. Since you've already changed the brakes and bled them, I would take a look at the master cylinder and the brake lines. If there is not enough fluid, that can cause a problem too. Really, since brakes are failry simple, it can only be one of a few things....brake components (rotors/pads/drums/shoes), brake lines (leaks/crimping), master cylinder, brake fluid. Systematically check each to make sure they appear in good working order. If they do, and the problem persists, then the only thing left is to take it to a mechanic. Typically, dealers are way over priced, and a decent/reputable brake shop would be a much more economical way to solve your problem. Good luck!
Bleed the master cylinder.& then rebleed the system.
how do you adjust rear brakes on a 1986 chevy silverado?
Check for leaks under vehicle. You may have blown a hole through a rusty brake line.
Yes all personal repairs are legal, if you are only replacing the pads and rotors/drums you can easily do it yourself. Bleeding the brakes is easier with 2 people.
It is a 3/8 Allen wrench
for 85 oldsmobile toronado what is the bleeding sequence on the brakes
First id have to get my back brakes on your Chevy 2500 silverado.
The 1997 Chevrolet Silverado rear brakes should automatically adjust themselves. Every time you back the vehicle up and hit the brakes the brakes adjust.
Could be a few causes of that symptom, but most likely air in the brake lines or moisture in the brake fluid. Start by replacing the brake fluid in the reservoir and bleeding the brakes.
The metering valve should be pressed down while bleeding the brakes. This is one of the steps to changing brakes.
Remove the original brakes and in stall it slowly.
try pumping the brakes up several times hard with the car off start at rt. rear then lft. rear to rt. frt. then lft. frt.
