Brake pads jammed on rear cycle wheel

check that a wire for the abs on the wheels where the bearing were replaced are still connected
check that the sensor is in the correct position to read the actuator bars

Have you inspected the brake disc/drum surface?

In the average brake system this refers to the tapered stub on the front suspension knuckle, which mounts the front hub and bearing assembly. It has a thread on the end for the front hub nut (not wheel nuts).

The actual appearance varies widely from car to car.

You'll need to trace the wiring - someplace there's a faulty connection.

Turn adjustement wheel through backplate hole to loosen the brake shoes. Pound off with a hammer and some wood so you don't damage drum.

you have to back off the shoe tension and then may be rusted around the axel and will require force with a hammer, a torch and maybe both

Hi again,

For some reason, I think the system has hanged. My windows shows that you are still typing a message for more than an hour. Our apologies for any inconvenience.

Anyway to your concern, if you were able to take it apart, checking would require that you use a continuity tester set at X 1. You need to check from the plugs back to where it went inside. The idea is to check the wires inside the cord. The meter/needle moving towards the extreme right indicates good continuity. Thereafter follow the two wires where they went inside. It maybe a circuit board, it maybe a fuse, or even the switch. The switch and fuse should also be checked for continuity.

Since your problem is a completely dead unit, then chances are the problem is among those listed above to be checked. If by chance none proved to be defective, am afraid that you have to seek the services of a qualified professional as all other tests requires a fair knowledge of electronics/electrical circuitry and components and possibly parts replacement.

Again our apologies.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
