BRAKE DRUM ACCESSORIES The interior of the drums must have a relatively even friction surface. A rough surface reduces the duration and effectiveness of braking. So if the drums are rough, they must reappear to bring the friction surface to a similar condition. The drums should always appear in pairs.
You shouldn’t switch sides after the drums have been on the machine for a while without rotating them first. This is because the drums and rotors wear out on the brake shoes / linings. Before starting any braking work, simply reassemble the new drum set and ready to use, so you can easily replace it under braking.
It all depends on whether you have combined a four-wheel drum or a disc drum. Being an all-wheel drive drum, I recommend having it repaired every 30-40,000 km (cleaning and functional check) and replacing it if necessary. This interval is also a good time to wash out the brake fluid.
The average cost to replace the brake shoe and surface drum is 248 to 350. Labor costs are estimated to be 211 to 267 while parts range from 37 to 83. The quote does not includes taxes and fees.
Reappearance of the drum and rotor Most stains on OReilly auto parts can reappear on the drum and rotor of the vehicle if they are within specification and show no signs of extreme wear. Surface treatment is essential for proper vehicle braking and pad life and should always be part of a full braking operation.
See full answer The hub and drums that can be rotated (machined) have a specification for how far they can be rotated, cast somewhere in the metal on the drum. Otherwise it is at the discretion of the brake workshop. The drums must not be turned unless there is …
Here are some signs that your brake drums are not working properly. Noise: When the brake shoe friction material wears out, the metal plate begins to sink into the brake drum. This leads to metallic scratches or creaks. Instead, the shoes bounce up and down, causing the brake pedal to pulsate.

It can take longer if your car has front and / or rear drum brakes as it can be more difficult to change the brake shoes. If you have access to a lift, pneumatic or power tools, or are very familiar with this task on your particular vehicle, you can probably do it comfortably in under 2 hours.
Brake drums can be painted by turning or grinding on a brake bench.
A vehicle’s rotors can last anywhere from 30,000 to 70,000 miles and sometimes longer. A certified mechanic like YourMechanic can inspect the rotors and advise you on their condition, they may not need to be replaced as often as the brake pads. Like the brake pads, they should be replaced in pairs.
Replacing drum brakes isn’t difficult, but it does require specialized tools and some care. In return, you save on vehicle bills. This article describes the general process, but you will still see the manual for the specific make and model of the car.
The average brake pad replacement cost is 150 per axle and can range from 100 per axle to $ 300 per axle. There is some other hardware in the brake system that also requires maintenance, including calipers and brake discs, but the most common service is to replace the brake pads.
If you’re wondering if you should convert drum brakes to disc brakes, the answer is a resounding yes. A drum-to-disc conversion is one of the best values to upgrade for your car.
Part 1 of 4: Prepare the vehicle
If necessary, unscrew the brake drum.
There are three types of drum brake systems: Dual Driver Pads, Driver / Tow Pads (also known as Single Driver Pads), and Duo Servos. Each type uses similar drum brake components but works slightly differently. All three types are activated in at least one direction. The first two types are brakes without brake boosters.
