There are a number of reasons why a brake caliper brush should be used to de-clog and clean brakes.
After constant use, the brakes on vehicles can become clogged with dirt, brake dust or even rust.
Failing to de-clog or clean your brakes can allow a build-up of dust, rust or dirt around the brake area, making it hard to remove and difficult to change parts.
A build up of rust can damage parts of the brakes.
A build-up of brake dust around the brake pads or shoes can cause the brakes to squeak.
Using a brake caliper brush will help you maintain your brakes, reducing the amount of dirt, dust or rust build-up while keeping them clean and operating smoothly.
