Brake Caliper Replacement: A Comprehensive Guide for Car


The brake calliper is an essential component of a vehicle’s braking system. It squeezes the brake pads against the brake rotor, slowing down the vehicle’s wheels. A malfunctioning brake calliper can cause serious problems, such as reduced braking power, uneven wear on the brake pads and rotor, and even a complete brake failure. This article will discuss everything you need to know about brake callipers and how to replace them.

Types of Brake Calipers

There are two main types of brake callipers: fixed and floating. Fixed callipers are mounted stationary and have pistons on both sides of the rotor. These pistons apply pressure on the brake pads, squeezing them against the rotor. Floating callipers, on the other hand, move back and forth on guide pins, squeezing the pads against one side of the rotor. Both types of calipers have their advantages and disadvantages. Fixed calipers provide more consistent and precise braking while floating callipers are more straightforward to maintain. Ultimately, the type of calliper you choose will depend on your vehicle and your driving needs.

Signs of a Failing Brake Caliper

A failing brake calliper can cause several issues that can be dangerous
for you and your vehicle. Here are some common signs that your brake
caliper may be failing:

  • Reduced Braking Power: If you notice that your vehicle is taking
    longer to stop than usual or the brake pedal feels spongy, it could be
    a sign of a failing brake caliper.
  • Uneven Wear on the Brake Pads and Rotor: If you notice that one of
    your brake pads or the rotor is worn down more than the others, it
    could be a sign of a stuck brake caliper.
  • Vehicle Pulling to One Side: If your vehicle pulls to one side while
    braking, it could be a sign of a stuck brake caliper.
  • Squeaking or Grinding Noise: If you hear a squeaking or grinding noise
    when you apply the brakes, it could be a sign of worn brake pads or a
    failing brake caliper.

If you notice any of these signs, it’s essential to have your brake system inspected by a professional mechanic.

Replacing Brake Calipers

Replacing a brake caliper is not easy and should be done by a professional mechanic. However, if you have some experience working oncars and have the right tools, you can attempt to replace the caliperyourself. Here’s how to replace a brake caliper:

Step 1: Gather the necessary tools and equipment. Before you start, you will need the following tools and equipment:

  • New brake caliper
  • Brake pads
  • Brake fluid
  • Brake hose
  • Wrenches and sockets
  • Brake bleeder kit
  • Jack and jack stands

Step 2: Raise the vehicle and remove the wheel.Use a jack to raise the vehicle and secure it with jack stands. Then,remove the wheel to access the brake caliper.

Step 3: Remove the brake calliper. Use a wrench or socket to remove the bolts holding the brake calliper. Then, remove the brake pads and set them aside.

Step 4: Install the new brake calliper. Install the new brake calliper in place of the old one and secure it with bolts. Then, install the new brake pads.

Step 5: Connect the brake hose. Connect the brake hose to the new caliper and tighten the bolts.

Step 6: Bleed the brake system.Use a brake bleeder kit to bleed the brake system and remove any air bubbles.

Step 7: Refill the brake fluid. Check the brake fluid level in the master cylinder and refill it as

Step 8: Test the brake system.

Before driving the vehicle, pump the brake pedal a few times to make
sure it feels firm. Then, test the brakes at low speeds to make sure
they are working correctly.

Tips for Replacing Brake Calipers

  • Always use high-quality replacement parts.
  • Make sure to use the correct size wrenches and sockets to avoid
    damaging the bolts or fittings.
  • Always use a jack stand to secure the vehicle while you are working
    underneath it.
  • When bleeding the brake system, start with the caliper farthest from
    the master cylinder and work your way closer to it.
  • Be sure to follow the manufacturer’s instructions for bleeding the
    brake system and refilling the brake fluid.


Replacing a brake caliper is a complex task that should only be
attempted by experienced mechanics. If you notice any signs of a failing
brake caliper, such as reduced braking power, uneven wear on the brake
pads and rotor, or a pulling sensation when braking, it’s important to
have your brake system inspected by a professional mechanic.

By understanding the different types of brake calipers and the signs of a
failing caliper, you can stay informed about your vehicle’s braking system
and take action if necessary. 


If you do need to replace a brake caliper,
follow the steps outlined above and be sure to use high-quality
replacement parts and the correct tools and equipment. With proper
maintenance and care, your vehicle’s braking system can provide reliable
and safe performance for years to come.
