2002 dodge neon right rear wheel locked up. Is it the drum brakes?

need to check your emergency cable its probably stuck

Replace Drums, shoes, wheel cylinders and brake hardware.

You need to manually adjust the brakes after putting new brake shoes on. The automatic adjuster has adjusted for wear in the old shoes which will make the new shoes too tight.

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.

Check to see if it is drum or disc first. Depending on which one it is, it could be a simple adjuster problem for drum brakes or if it is disc breaks you may have a bad caliper. The only way to find out is to take it apart and look at what the car has for brakes.

may be a frozen e-brake cable or bad wheel cylinder or something fell apart in drum holding shoes. you must remove drum and take a look.

Here are the steps;
) Park on a level surface. safety
) Block all the other wheels. safety
) Put the vehicle gearshift in PARK. safety
) Release the handbrakes.
) Slightly break the rear wheel lug nuts seal while on ground. Just loosen do not remove.
) Jack up the rear wheel.
) Check to see the wheel will turn so you know the brake shoes are not binding against the drum.
) Now you can remove the lug nuts and wheel.
) Remove the drum. Some times the drum has frozen on with rust. You may have to use a hammer and hit along the drum near the outer edges to break it free.

No need

remove back wheel and drum should come off sound like broken brake spings

sounds like the e brake cable has stuck, see if you can pull it to activate the e brake at that wheel if there is already tension on it you can cut the cable and replace it later (especially if its an automatic) please rate and good luck -jeff
