How to Bypass a Brake Caliper? Brake calipers are one of the most important components of a vehicle’s braking system.
They are responsible for applying pressure to the brake pads, which then clamp down on the brake rotors to slow or stop the vehicle.
However, if a brake caliper fails, it can lead to a dangerous situation on the road. In this article, we will discuss how to bypass a brake caliper in case of an emergency situation.
What is a Brake Caliper?
Before we dive into how to bypass a brake caliper, let’s first understand what a brake caliper is and what it does.
A brake caliper is a component of a disc brake system used in vehicles to slow or stop the wheels’ rotation.
The brake caliper contains a piston and brake pads, which apply pressure to the rotor, causing the vehicle to slow down or stop.
When the driver presses the brake pedal, brake fluid is pushed through the brake lines, forcing the piston in the brake caliper to squeeze the brake pads against the rotor.
This creates friction and slows the wheel’s rotation, bringing the vehicle to a stop.
Brake calipers are typically made of aluminum or steel and come in different sizes and shapes, depending on the vehicle’s make and model.
There are two types of brake calipers: floating and fixed. Floating brake calipers move with the rotor, while fixed calipers remain stationary.
Both types of brake calipers have their advantages and disadvantages, and the choice between them depends on the vehicle’s application and design.

Signs of a Damaged or Stuck Brake Caliper
A brake caliper is an essential component of a vehicle’s braking system, responsible for squeezing the brake pads against the rotor to slow or stop the wheels.
A failing brake caliper can compromise the safety of your vehicle, making it essential to know the signs of a failing caliper. Here are some common signs that indicate a failing brake caliper:
– Uneven brake pad wear
A failing brake caliper may cause uneven wear on the brake pads. You may notice that one pad is wearing more quickly than the other or that the pads on one side of the vehicle are wearing faster than the other side.
– Vehicle pulls to one side
A stuck brake caliper can cause the vehicle to pull to one side while braking. This can be dangerous, especially at high speeds, as it can cause a loss of control of the vehicle.
– Squealing or grinding noise
A failing brake caliper can cause a squealing or grinding noise when you apply the brakes. This is often a sign that the brake pads are worn down and need to be replaced, but it can also indicate that the caliper is failing.
– Brake fluid leak
A leaking brake caliper can cause a loss of brake fluid, which can lead to a soft brake pedal or even complete brake failure. If you notice brake fluid on the ground under your vehicle or a low brake fluid level, it’s important to have your brakes inspected immediately.
– Burning smell
A seized brake caliper can cause the brake pad to rub against the rotor continuously, generating a burning smell. If you smell a burning odor coming from your wheels, it’s likely due to a stuck brake caliper.
If you notice any of these signs, it’s important to have your brakes inspected by a mechanic as soon as possible.
Failing to address a failing brake caliper can lead to more significant and costly repairs, as well as compromising the safety of your vehicle.
Step-by-Step Guide How to Bypass a Brake Caliper
It’s important to note that bypassing a brake caliper should only be done in emergency situations and for a short period of time.
It’s not a permanent solution and can compromise the safety of your vehicle. With that said, if you find yourself in a situation where you need to bypass a brake caliper.
Here’s a step-by-step guide to help you:
Step 1: Determine which brake caliper is failing
If you notice signs of a failing brake caliper, such as uneven brake pad wear or a burning smell, you’ll need to determine which caliper is failing.
This can be done by inspecting the brake pads and rotors for signs of uneven wear, or by jacking up the vehicle and rotating the wheels while listening for any unusual noises.
Step 2: Disconnect the brake line
Once you’ve identified the failing brake caliper, you’ll need to disconnect the brake line that leads to the caliper.
This can be done by loosening the brake line fitting with a wrench and then gently pulling the line away from the caliper.
Step 3: Install a brake line plug
To prevent brake fluid from leaking out of the brake line, you’ll need to install a brake line plug.
This is a small, threaded plug that screws into the brake line fitting and seals off the brake line.
Step 4: Secure the plug
Once the brake line plug is installed, you’ll need to secure it in place. This can be done by tightening the plug with a wrench or by using a locking clip or pin to hold the plug in place.
Step 5: Test the brakes
Once the brake line plug is installed and secured, you’ll need to test the brakes to ensure they’re working properly.
You can do this by gently pressing down on the brake pedal and checking for any leaks or unusual noises.
It’s important to note that your vehicle’s braking performance may be compromised with a bypassed caliper, so exercise caution when driving.
Step 6: Have your brakes checked by a mechanic
Bypassing a brake caliper is only a temporary solution and should not be used as a long-term fix.
It’s important to have your brakes inspected by a mechanic as soon as possible to identify the root cause of the caliper failure and make any necessary repairs.

What Causes Brake Calipers to Fail?
Brake calipers are an essential component of your vehicle’s braking system, responsible for squeezing the brake pads against the rotor to slow or stop the vehicle.
Like any mechanical part, brake calipers can fail over time due to a variety of reasons. Here are some common causes of brake caliper failure:
- Piston Seals: The piston seals inside the brake caliper can wear out or become damaged over time, causing brake fluid to leak and affecting the caliper’s ability to apply pressure to the brake pads.
- Corrosion: Corrosion can occur on the brake caliper and its components due to exposure to water, salt, and road debris. This can cause the caliper to become stuck or seize, leading to uneven brake pad wear or even complete brake failure.
- Contamination: Dirt and debris can accumulate inside the brake caliper, causing it to become clogged and prevent the brake pads from moving freely. This can lead to overheating of the brake system, reduced braking performance, and premature wear of the brake pads and rotors.
- Worn Brake Pads: If brake pads are not replaced in a timely manner, they can wear down to the metal backing plate, which can cause damage to the caliper piston and other components.
- Overheating: Overheating of the brake system due to heavy use, high speeds, or driving in mountainous areas can cause the brake caliper to fail. This is because excessive heat can cause the brake fluid to boil, which can damage the caliper seals and other components.
Regular maintenance and inspection of your vehicle’s braking system can help prevent brake caliper failure.
It’s important to have your brakes inspected by a qualified mechanic at least once a year, or more often if you notice any signs of brake problems, such as a soft or spongy brake pedal, uneven brake pad wear, or unusual noises while braking.
Can I drive with a bypassed brake caliper for a long distance?
No, bypassing a brake caliper will affect the braking performance of your vehicle. It is not recommended to drive for long distances with a bypassed brake caliper.
What is a brake caliper block?
A brake caliper block is a device that prevents the brake fluid from leaking out of the brake system when a brake caliper is removed.
How often should I have my brakes inspected?
It’s recommended to have your brakes inspected every 12,000 miles or once a year, whichever comes first.
Can I replace just one brake caliper?
It’s recommended to replace both brake calipers on the same axle to ensure even braking performance. However, if only one brake caliper is failing, it can be replaced individually.
How much does it cost to replace a brake caliper?
The cost of replacing a brake caliper can vary depending on the make and model of your vehicle and the location of the repair shop. Generally, the cost ranges from $200 to $500 per caliper.
Bypassing a brake caliper is not a recommended solution for a failing brake caliper. It should only be done in emergency situations and for a short period of time.
Remember to always follow safety procedures when working on your vehicle’s braking system and seek the assistance of a qualified mechanic if you are not confident in your abilities.
Your safety and the safety of others on the road depend on the proper functioning of your braking system.
