Now for my brakes. The right rear brake locks up so badly that it even pulls the rear of the car down. I have completely rebuilt them and bled the entire system.

The brakes even stay locked temporarily after releasing the brake pedal. There is a significant POP when they do release. Going in to winter and I am at the point of just disconnecting the brakes on that side.

If the brakes are locking in that way I would suspect you have a partially blocked flexible brake line on that wheel. When you apply the brakes you can force the fluid through but when you release them the fluid will not flow back up the line and is locking your brakes as a result.
You will not see deterioration from the outside of the hose because brake hoses deteriorate from the inside especially near each end.

If you cannot fix it yourself take it to a brake specialist to diagnose.

Look forward to a civil law suit and a criminal prosecution if you disconnect your rear brakes and have an accident which I can absolutely guarantee you will.

Testimonial: "Thank you for your valuable diagnosis. It was very helpful. Now to tear in to this thing."

Sounds like you need a master cylinder. If the fluid was full when this all started then I would suspect a master. Check the rear and front brakes for leakage. You'l have to remove the rear drims to inspect the whel cylinders. If no leaks are found its the master cylinder

SOURCE: I replaced the master cylinder in my 1993 Buick

You have a 16 year old car and I would bet the brake fluid has never been changed. First thing to do is replace all the brake fluid in the system and bleed the brakes. Start at the RR then LR >> RF and end at the LF. The contaminated brake fluid may be causing the calibers to stick. You may end up having to replace the calibers. It is also possible you have a brake hose that is collapsing. If so the brake hoses will need to be replaced. It can also be the brake booster causing this but that is rare. Possible but rare.

SOURCE: Brakes uneven and jerky

this could just be "sticky pads" or there worn right down to there limit
you still need to strip the brakes out to check them out,,if there sticky put some copper grease on the back of the brake pads,,not on the brake pads!!!! only the backs fo them this stops then sticking and also from squealing,,

I had my back brakes replace which are drum brakes and also got new drums. After I got my car back the brake pedal was squishy and went to the floor and pulled to the right. I was then told that the front...

Okay, Sounds like you have a bad brake bleeder on the right side. Check beforehand by calling the auto parts stores to see if they carry brake bleeders. It is absolutely necessary for all lines to bleed.
There is a pattern to use when bleeding brakes. The longest rear line first, next longest rear line, then the passengers front and finally the Drivers front.
As each line is bled. the Master cylinder should be monitored for low fluid. When the rear brakes are working, you will hear the brake springs work when the brake pedal is pressed.
It is possibly to have a plugged brake line which can only be determined once the brake bleeder releases the fluid. There can be variations in the brake adjustment, so before putting on the wheel, adjust the star wheel evenly from side to side. Hang (Fit) the drum to the axle and snug up with the lug nuts. Spin the rear wheels and note that each side is evenly touching the brake linings.

I have changed the rear rotors and brake pads, bled the brakes after putting itall back together. Seemed to have brakes but then shortly thereafter they are like a sponge. Last time I tried bleeding them...

Hi, bleeding your rear brakes with engine running, you should get enough pressure out of the lines to squirt 3-4 feet. In other words, good pressure. If all you get is a trickle, you probably have a bad master cylinder. Just because its full of fluid, does not mean the seals arent shot. If you have bled them in order, left rear,right rear,left front,right fornt and have bled them enough to get fresh fluid out of each one without achieving good solid pressure at all wheels, replace your master cylinder. There is a proportioning valve, but usually it will affect only one wheel when going out, usually the left rear.
Brake pedal height comes from the rear brakes, so if you have bad pressure there, you will never get a good pedal. Eventually with a bad master, your brakes will go completly out..Mike

Changed front brakes on 2000 grand cherokee, bled brakes, and pedal seems spongier than normal

You still have air in the brakes,start at the master cylinder,then the rear,right wheel,left rear,and right front,then the left front.Make sure the calipers are releasing completely ,if they are not,then a brake hose could be bad.

Rear brakes wont apply consistantly

1- brake system low on fluid,
2- improperly bled (air in lines).
3- Master cylinder (applies equal pressure to all 4 cylinders) is bad.

96 Cavalier passenger rear brake lock up when wet or cold

Bad PROPORTION VALVE ... the back brakes should only be doing 30% of the stopping with a bad proportion valve it will send more pressure to the back during braking and cause it to lock up. Good Luck and thanks for using FIX YA
