Causes of Rusty Brake Caliper Pistons and How to Clean Them
Rusty brake caliper pistons can affect the car's braking system and driving safety. Rust can make the piston lose its elasticity and reduce its function. Therefore, you need to know what can actually cause the caliper piston to rust so you can prevent it before it happens.
Causes of Rusty Car Brake Caliper Pistons and How to Clean Them
The role of the brake caliper piston in the car's braking system is crucial. Its job is to serve as the piston holder that will press the brake pads when braking occurs. This means that if this caliper piston part is damaged, the car's braking system will automatically not work.
Given its very important role, you must know important information about the causes of rusty car brake caliper pistons and how to clean them as follows:
Causes of Rusty Car Brake Caliper Pistons
One of the most common cases is that car brake caliper pistons become rusty because the underside of the car is left dirty for a long time. Dirty here means dirt that has accumulated and clumped, for example, due to frequent exposure to rainwater and mud that is not cleaned immediately. Accumulated dirt can accelerate the corrosion or rusting process on the metal elements of the caliper piston.
Moreover, the braking system in the car is also an area that is difficult to reach. This is why even if you often clean your car, there is still a possibility that the brake caliper piston remains dirty and has not been cleaned thoroughly.
Another cause that also frequently leads to rusty brake caliper pistons is the infrequent replacement of brake fluid. Eventually, the dirty brake fluid is still used, which can also accelerate the corrosion process because dirty brake fluid can contain many particle residues that arise from the friction of the brake pads.
In addition, dirty brake fluid may contain water particles due to condensation in the reservoir where the fluid is stored. Besides dirt, water is also a factor that can accelerate the onset of rust.
How to Clean Rusty Car Brake Caliper Pistons
If your car's brake caliper piston has already rusted, there is no need to panic. For rust that is not too severe, you can clean the caliper piston by sanding it until the rust is gone and the surface is smooth again.
However, if the rust on your caliper piston is too severe to be sanded, you can replace it with a new caliper piston.
Next, to prevent rust from reappearing, make sure you frequently clean the underside of the car thoroughly. Additionally, don't forget to periodically drain the brake fluid to avoid accelerating corrosion on the brake caliper piston.
