How do i change a rear wheel cylinder on a 20000 dodge neon

NEED TO PRESSURE BLEED FROM MASTER CYLINDER ! OR HAVE A HELPER PUSH ON BRAKE PEDAL WHEN YOU RELEASE BLEEDER VALVE @ EACH WHEEL, RR-1st, LR- 2nd, RF- 3rd, LF-4th. gravity doesn't cut it dude !

Replace Drums, shoes, wheel cylinders and brake hardware.

Back up... on asphault and it will usually release... Usually this is caused by either a sticking ebrake cable, overly worn drums w/New shoes, and sometimes a bent spindle.. Dont keep applying the ebrake this will hinder the problem if any of the above are the issue. Once it frees up take it apart, if the cables stuck many times you can back off the cable adjustment and pry it back to release it, then replace it accordingly. If it isnt the cable, once its loosened up, back off adjuster wheel, remove drum and take it to your local parts store and have it sized, they will tell you if its out of spec, also look for wheel cylinder leakage and contamination.. Lastly if neither are the problem, then it probably has a bent spindle and gets jammed at certain brake application.. I have run into all three on NEONS

start from the rear driver side, and then the rear passenger side, and the front passenger side,and then the driver side make sure you keep plenty of fluid in the master cylinder during bleeding proccess

There will be two bolts on the back of the wheel cylinder that secure it to the backing plate.
- Remove the drums and all brake components obstructing the removal of the wheel cylinders.
- Remove the brake lines going into the back of the wheel cylinders, use plenty of spray lube, and work with the fittings on the lines gently, you may have to warm them with a torch to avoid damage if they are frozen.
- Replace wheel cylinders, re-connect brake lines
- Re-assemble rear brake components
- Bleed air from brake system
-Done!

Your problem would appear to be something amiss in the rear brake on the locked wheel. If a wheel sylinder was leaking the brake shoes would become "sticky" and cause the shoes to "lock on" to the drum. Or if the brake was out of adjustment, the assembly could come apart and pieces of it jamb the wheel. This problem is fairly common with drum brakes. You need to have the rear brakes serviced, & checked for fluid or grease on the braking surfaces. All leaks fixed, backing plates cleaned, the wheel cylinders overhauled, & the brake shoes replaced.

If it is leaking from the top area of the plate, and you have drum brakes...then the wheel cylinder is leaking.

THE BRAKE LINING ON ONE OF THE SHOES MAY HAVE LET GO AND OVERLAPPED THE OTHER ONE,CAUSING IT TO BIND UP..IF NOT,TRY OPENING BLEEDER SCREW AND SEE IF IT RELEASES..IF IT DOES,REAR BRAKE HOSE MAY BE HOLDING WHEEL CYLINDER PISTONS OUT KEEPING BRAKE ON..YOU'LL NEED TO REMOVE AFFECTED DRUM AND INSPECT BRAKES AND REAR HUB/BEARINGS

You need a pullers to get it off.But if your lucky putting a screwdriver between the drum and back-plate and pize it when your hitting with a hammer it may come off.good luck.

Hi my name is Allen!

To change the rear wheel cylinders on your neon, first take the wheel and the drum off, next using the proper size line-wrench take the brakeline off the wheel cylinder, next take the spring off the upper part of the brake shoe and pry back on the upper part of the shoe's, this will give enough space to remove the wheel cylinder without taking all the other parts off the shoes, next, take the 2 bolts off the wheel cylinder that hold it into place and install the new one in reverse procedure.

Note: Do one side at a time, becuse this will make easier to bleed the system. once you have one side done with the drum back on and every thing tight, then you will need someone to help bleed the brakes.

Note: make sure you never run out of fluid in the master cylinder are you will have to start the bleed procedure all over again.

Note: Have the person helping you, pump the brakes 5 times then hold the brake pedal to the floor and make sure they hold it there until you have loosened the bleed nut and tightened it back up again, once you have done that, have them pump the brakes and hold it down again. Do this procedure several times making sure not to run out of fluid in the master cylinder. Once all the air is out of the system replace the other whell cylinder on the other side and bleed it the same way.

Note: make sure before bleeding the system that all components are completely installed, because if you try to bleed the system with the drums off and before placing the shoes back where they belong and installing the spring and drum the wheel cylinder parts will be pushed out of it.
