As a car owner, one of the most critical safety components of your vehicle is the brake system. Without properly functioning brakes, you put yourself and other road users in danger. One of the key parts of the brake system is the brake calliper. In this article, we’ll discuss how to tell when your brake callipers need replacing.

What is a Brake Caliper?

Before delving into the signs that indicate brake calliper replacement is necessary, it’s crucial to understand what brake callipers are and how they work. A brake calliper is a crucial component of the brake system that applies pressure to the brake pads, which in turn, press against the brake rotor, causing the vehicle to slow down or come to a complete stop.


Brake callipers come in two types: fixed and floating. Fixed callipers are firmly bolted to the hub of the wheel while floating callipers move along the wheel assembly. The latter is less expensive and typically found in smaller vehicles.

Signs That Indicate Your Brake Calipers Need Replacing

Squeaking or Grinding Noises When Braking

If you hear an unusual squeaking or grinding noise when braking, it’s a clear sign that your brake callipers need attention. The noise is typically an indication that the brake pads are worn out, and the metal backing of the brake pad is grinding against the brake rotor.

Vibration While Braking

Another sign that your brake callipers need attention is when you experience unusual vibrations while braking. This could indicate that the brake rotor has become warped or distorted. In most cases, a warped rotor is a result of the brake pads and callipers failing to apply equal pressure to the rotor, causing it to wear unevenly.

Reduced Braking Power

If you notice that your brakes are not as responsive as they used to be, it could be an indication that your brake callipers are failing. This could be due to worn brake pads or a malfunctioning brake calliper.

Leaking Brake Fluid

Brake fluid plays a vital role in the brake system, and any leaks could lead to brake failure. If you notice a pool of brake fluid under your car or reduced brake fluid in the reservoir, it’s a clear indication that your brake callipers or brake lines may be leaking.


Uneven Brake Pad Wear

Finally, if you notice uneven brake pad wear, it’s a clear sign that your brake callipers are not applying equal pressure to the brake pads. This could lead to uneven brake pad wear and a reduced lifespan of the brake system.

When to Replace Brake Calipers

If you notice any of the signs mentioned above, it’s essential to have your brake system inspected by a qualified technician. The technician will inspect the brake calliper components and determine if they need replacing or repair.


Replacing brake calipers is an intricate process that involves disassembling the brake system and replacing the defective components. The cost of replacing brake calipers varies depending on the make and model of your vehicle.
