What is a Brake Caliper and When to Tell That It’s Already Bad

It’s important that you understand the functions of the brake system and what exactly it does.  The brake caliper is an integral component of the brake system in your car. When you get into trouble with your brakes, and you want to stop your vehicle from skidding to a stop, the brake caliper performs an important role. It controls how hard or soft your brakes will apply to the road surface.

The brake system works by having two main components – the brake pads and the brake calipers. These two parts work together to provide a smooth and controlled braking process for your vehicle. While the brake pads are responsible for absorbing the shock from your wheels, the brake caliper applies the brakes’ power by pulling the piston rod that’s attached to the pads towards the rotors. Thus, these two components work in conjunction with each other to ensure a perfectly balanced braking process.

However, when you find that the brake pads aren’t working well or worn out, they may not be able to give you the support you need. This is where the brake calipers are important. Brake calipers are placed on top of the rotor to control how much force is used to apply braking pressure to the wheels. You can choose to apply brake caliper paint to add more brilliance to your car and acts as a preventive measure that helps to prevent them from developing rust. . It’s important to maintain the brake in good condition so that it can give you optimum braking power.

How to Tell if Your Brake Calipers Has Gone Bad

  1. Vehicle Steers to One Side

  1. Fluid Leaks

Brake calipers are activated by hydraulic fluid. When you see that it starts to develop fluid leaks, you should consider replacing them right away. However, you can prevent your calipers from developing a leak with regular, preventive maintenance for your car.

  1. Soft Brake Pedal

If your brake caliper is leaking, it can soften your brake pedal. Aside from leaking, having air in the system is another cause for the soft brake pedal. There could also be air in the caliper that needs to be removed. You can temporarily remove the caliper and move it around to try to remove the air.

  1. Uneven Wearing of Brake Pad

When you notice that your brake pads are wearing unevenly, there’s a high chance that your brake calipers are at fault here. Over time, your brake pads will wear out and will be needing a replacement after a long time of use.

  1. Clunking Sounds

If you hear clunking sounds as you drive, you should refrain from driving your vehicle and have your calipers replaced immediately. Clunking sound happens when the caliper bracket that is responsible for holding the caliper in place breaks. When this happens, the breaks may lock and might disable you from steering the wheel,

  1. Metallic Rubbing Noise

Similar to clunking sounds, when you hear even just a soft metallic rubbing noise that is similar to a squeal, chances are that the brake calipers are not in a sturdy position. When this continues to happen, it might lock up and might prevent your wheel from turning which is a call for danger. When this happens, have your brake calipers replaced immediately.


If you’re looking to save money on a replacement caliper, there are a few things to keep in mind. When you’re choosing a brand of a caliper, consider what type of brake fluid your vehicle has.

Adding paint to your brake caliper is care as you’ll be preventing the formation of rust making it in its best shape as long as possible
