Remove the wheels and tires first, next the dust cap, then the center nut and the washer, and finally the brake-drum bolts. Make sure to disengage the brake hose before you remove the drum. Also inspect the spindle to evaluate if it needs to be replaced. With rear conversion, you will also have to remove the parking brake.

Why is my rear bike brake not working?

What causes brakes to not engage?
The most common cause of brake failure is loss of brake fluid. The fluid transfers the force you exert by pushing down on the brake pedal to the brake disks that slow and stop your car's wheels. You can usually detect a leak before getting on the road because you'll see it underneath your vehicle.
Should you pump disc brakes?
Therefore, according to the experts: You do not have to pump your brakes. In fact, if you pump them while braking hard, you will lose the benefits of the ABS. During emergency hard braking, apply firm pressure to the brake pedal; do not take your foot off the brake until your vehicle comes to a full stop.
How to replace brake calipers?
Replace calipers if necessary. Make sure the brake fluid reservoir is securely closed , especially if you opened it earlier to allow for fluid to expand. Remove the "banjo" bolt holding the brake hose to the caliper. This is a special hollow bolt that allows fluid to flow through it; don't damage it or lose it.
How to remove set screw on brake rotor?
You may need to remove a set screw and/or use a rubber mallet to loosen the rotor. You may need an impact driver (hammer it while twisting counter-clockwise) to remove a set screw.

What happens if you switch calipers?
If you accidentally switch the left and right calipers and install them on the wrong side (easier to do than you think!), the bleeder fittings will be in a lower position, which will result in trapped air inside the caliper fluid chamber , which will make bleeding the brakes impossible to do.
Why do my brakes make a grinding noise?
This is a sign of uneven wear of your brake pads caused by uneven pressure in your brake lines. If the brakes have a grinding noise, this means rotors are done, spent, wasted, or whatever you want to call it, just replace them.

These instructions will include a full front brake replacement. ...

What is disc brake?
Disc brakes use calipers mounted to the fork in front and the frame in back, and rotors (the discs) mounted to the wheel hubs. When you squeeze the brake levers, the brake pads inside the calipers squeeze the discs to slow the wheels. Almost all modern mountain bikes come equipped with disc brakes, and more and more road ...
Why do disc brakes wear down?
Disc brakes have pads that wear down over time due to normal use. This can lead to slower brake response times, and it can require more effort from you to engage your brakes. Look to see if your brake pads are glazed or significantly worn.
How to get brake pads closer to rotors?
If the pads are okay, turn the adjustment dials located on the calipers to bring the pads closer to the rotors. The proper distance between the rotor and brake pads depends on the style of brakes you have, so consult the instruction manual provided with your brakes.
Why are my brakes so slow?
Cables can fray, rust and/or weaken over time. When this happens, the extra slack in the system can cause a slow response when you squeeze the brake levers.
How to check brakes?
To check the position of your brake assemblies, visually inspect both the front and the rear calipers and make sure the rotors are centered between the brake pads. Each pad should make contact fully with the rotor when the brake is engaged.
How to check brake pads on a car?
Check the pads by removing the wheel and looking into the space where the rotor spins. If the pads are glazed, remove them from the calipers and lightly scuff them on a piece of sandpaper laid on a flat surface. If the pads are less than 3mm thick, including their metal holder, they need to be replaced.
What causes a brake to be off center?
Off-center or miss-alligned brakes cause one side of the brakes to make contact with the rotor before the other one does, resulting in poor braking power and noise. Re-adjustment in many cases involves simply loosening the bolts and moving the caliper slightly from side to side to properly position it.
