What Is A Brake Caliper?

The brake caliper is a vital component of the braking system.

It houses the brake pads and piston that actuates the pads.

When you press the brake pedal, hydraulic fluid is forced into the caliper, pushing the piston outward.

This, in turn, makes the brake pads against the rotor or drum, causing friction that slows down or stops your vehicle.

It’s important to note that not all brake calipers are created equal.

There are two main types of brake calipers: fixed and floating.

Fixed brake calipers are mounted to your car’s suspension using bolts while floating brake calipers are mounted using pins.

Fixed brake calipers are more common on larger vehicles like trucks and SUVs, while floating brake calipers are more common on smaller cars like cars.

Fixed brake calipers have one or more pistons permanently mounted to a frame, whereas floating brake calipers have pistons connected to an inner pad carrier via a sliding pin.

Most vehicles nowadays use the latter type as it provides better braking performance.

My Car’s Brake Caliper Working:

Your car’s brake caliper is one of your vehicle’s most critical safety features.

The brake caliper houses your car’s brake pads and helps to squeeze them against the rotor when you hit the brakes, slowing down or stopping your vehicle.

If you have ever wondered how your brake caliper works, wonder no more!

As we mentioned before, the primary function of the brake caliper is to house the brake pads and squeeze them against the rotor.

But how does it do that?

Let’s take a closer look.

The brake caliper comprises two main parts: the piston and the cylinder.

The piston is what does the squeezing, while the cylinder holds everything in place.

When you hit the brakes, hydraulic fluid flows into the cylinder from your car’s braking system.

This hydraulic pressure forces the piston to move outwards, which pushes the brake pads against the rotor.

The friction between the brake pads and rotor slows down or stops your car.

No matter what type of brake caliper your car has, they all work in basically the same way.

Now that we know how brake calipers work let’s take a look at how to compress them properly.

Compressing a brake caliper is essential when you need to do any maintenance on your brakes, such as changing the pads or rotors.

If you don’t compress the brake caliper correctly, it can cause severe damage to your braking system.

That’s why it’s essential to know how to do it correctly!

Ways To Compress A Brake Caliper

There are two main ways to compress a brake caliper: a C-clamp or a brake caliper compression tool.

We will go over both methods so you can choose the one that is best for you.

 C-Clamp

Using a C-clamp is the most common way to compress a brake caliper.

To do this, you will need to place the C-clamp on top of the piston and tighten it until the piston is compressed enough to allow you to remove the old pads and install new ones.

Ensure not to over-tighten the C-clamp, as this can damage the piston.

Once the new pads are in place, remove the C-clamp and allow the piston to extend back to its original position.

Brake Caliper Compression Tool

If you don’t have a C-clamp or prefer not to use one, you can also use a brake caliper compression tool.

This is a specialized tool that is designed specifically for compressing brake calipers.

To use it, insert the tool into the cylinder and turn the handle until the piston is compressed enough to allow you to remove the old pads and install new ones.

Again, make sure not to over-tighten as this can damage the piston.

Once the new pads are in place, remove the tool and allow the piston to extend back to its original position.

That’s all there is to it!

Compressing a brake caliper is not tricky, but it is essential to do it correctly to avoid damaging your car’s braking system.

If you’re planning on doing any work on your brakes, it’s important to know how to compress the brake caliper.

This will allow you to remove the old brake pads and install new ones, as well as bleed the brakes if necessary.

While it may seem like a difficult task, compressing a brake caliper is actually quite simple and only requires a few tools.

With this guide, you’ll learn how to compress a brake caliper in just a few minutes.

Tools You’ll Need:

  • A brake caliper compression tool
  • A C-clamp
  •  New brake pads (if necessary)

Step One: Preparing To Compress The Brake Caliper

Before you begin, it’s important to make sure that you have everything you need.

Once you have your tools assembled, locate the bleeder screw on the caliper.

This is a small valve located on the top or side of the caliper that allows air to escape when bleeding breaks.

Next, use a piece of cloth or tape to cover the bleeder screw so that dirt and debris don’t enter it while you’re working.

With the bleeder screw covered, go ahead and place the brake caliper compression tool onto the caliper.

This tool will have two arms that fit over the top and bottom of the caliper, and a screw in the middle that can be tightened to compress the caliper.

Step Two: Compressing The Brake Caliper

Once you have the compression tool in place, it’s time to start compressing the brake caliper.

To do this, simply turn the screw in the middle of the tool clockwise.

As you turn, you’ll feel resistance as the arms of the tool begin to push against the sides of the caliper.

Continue turning until there is about ½ inch (12 mm) of space between them.

At this point, you can go ahead and remove the old brake pads.

To do this, simply unscrew the retaining clip that holds them in place and slide them out.

Once the old pads are removed, you can install the new ones by reversing the process.

Step Three: Releasing The Pressure On The Brake Caliper

Once you have installed the new brake pads, it’s time to release the pressure on the caliper so that you can reattach it to the vehicle.

To do this, simply turn the screw in the middle of the compression tool counterclockwise until it is loose enough to be removed.

With the pressure released, you can go ahead and remove the caliper from the vehicle.

Compressing Calipers: How Do I Do It?

Compressor kits are very expensive but you will need to purchase a kit that is compatible with your car’s make and model.

Follow the instructions provided in the kit to compress your caliper.

Most compressor kits come with a ratchet, an impact wrench, and a socket set.

The ratchet is used to loosen the bolts on the caliper.

The impact wrench is used to remove the old brake pads from the caliper.

The socket set is used to install the new brake pads onto the caliper.

Compressing your caliper is a very important part of maintaining your car’s braking system.

If you do not compress your caliper properly, it could cause serious damage to your car’s brakes.

Always follow the instructions provided in your compressor kit carefully to avoid any accidents.

What Is The Purpose Of Compressing My Brake Caliper?

The caliper houses the brake pads and uses hydraulic pressure to grip the rotor whenever you hit the brakes.

Over time, the seals in the caliper can start to leak, which will cause the caliper to lose its grip on the rotor.

This can lead to decreased braking power and increased wear on your brake pads.

To prevent this from happening, you need to compress your brake caliper periodically.

Compressing your brake caliper will help to reseal any leaks in the caliper and make sure that it is gripping the rotor properly.

Compressing your brake calipers is a fairly simple process that does not take much time or effort.

However, it is important to follow all instructions carefully to avoid any accidents.

Always consult your car’s manual or a professional mechanic if you are unsure about anything.

My Caliper Isn’t Compressing: What Should I Do?

Well, it is more common than you think.

Over time, your caliper can become frozen due to corrosion.

This usually happens when you do not use your car for a long period of time or if you live in an area with high humidity.

When the caliper becomes frozen, it will not be able to compress the rotor properly.

As a result, you will hear a loud noise when you press the brake pedal or notice that your car is taking longer to stop.

If your caliper is stuck, there are a few things that you can do to try and fix it: 

  • Use a penetrating oil: This will help break down any rust that has built up on the caliper.
  • Use a caliper piston tool: This will help push the piston back into the caliper.
  •  Replace the caliper: If neither of these options works, you may need to replace the entire caliper.
