Is there a page from a repair manual that somebody can show me on how to replace rear brake pads and how they can be bled???

Once you have bled the air from the brake lines,clamp off the front brake hoses carefully.Does the pedal feel better now?
Then the pad /caliper fit is allowing too much play.Is the pedal the same?Then clamp the rear hose and try the pedal.Is it fine with the rear hose clamped?If so we now know the problem is at the rear brakes.One common low pedal rear brake cause is brake shoes that do not fit the drums.Remove the drums and look at the shoes,are they showing contact wear fully or just in the middle of the shoe?Remove a shoe and place it in the drum.Can you rock the shoe against the drum surface?Once drums have been resurfaced,the shoes will not fit fully against the drum allowing the shoe the flex when applying pressure to it and this can easily create a low soft brake pedal. Of course rear brake adjustment must be correct once brake shoe contact is correct.To correct brake shoe contact,have your shoes re arc-ed to fit resurfaced drums or install new drums.Don't overlook brake master cyl /brake pedal push rod adjustment too.

Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

If you have drum brakes on the rear the brakes probably need adjusted. murf427

Buy a repair manual for the vehicle from your local auto parts store...they are under $20. The repair manual will show you step by step what needs to be done and more than likely has a few pictures to help out. Trying to write it out step by step here would take a long time and would be at least a few pages long.

Stuff to buy:
New Calipers
New Rotors
New Brake Pads
Brake Fluid
Brake Cleaner
Repair Manual
If the pads do not come with new clips, you may have to buy 2 of them.
Grease

Basic Tools needed:
Hex Wrench Set
Basic wrench set
Socket Set
Tire Iron
Floor Jack and Jack Stands
Hammer might come in useful, along with a bigger regular screw driver.
C-Clamps
Sand Paper/Steel Brush
Rags
A helper to bleed the brakes.

If vehicle has ABS, that system also might need to be bled...repair manual will let you know.

Before installing the new rotors, spray/wipe them down good with brake Cleaner...they are oiled for storage/shipping.

Hope this helps.

vacuum leak in booster is a good possibility

Hi:
If you have replaced all pads, and see no leaks at any wheel, and have bled your brake system, then most likely your brake master cylinder has failed.

may be bad caliper could be why pad went to metal/metal

make sure that the abs connect for that side is connect properly and the right amount of brake fluid is there

sounds to me like the abs relay is bad maybe $75 repair at the dealer

probably need to be bled again on that side
