When the brake pedal is removed, a sticky brake calliper fails to release the brakes correctly. This may lead to irregular wear of the brakes, lower fuel economy, and worse braking ability. A rusted piston, a seized sliding pin, a broken brake line, and other problems may all contribute to a sticky brake calliper. To guarantee safe driving and stop future damage to the brake system, it is critical to solving this problem right away.
The brake callipers strain the brake pads against the braking rotors when you press the brake pedal, which causes friction and slows the automobile down. The brake calliper should release the brake pads from the rotor once the brake pedal is released, enabling the vehicle to travel without restriction. However, the brake calliper cannot separate the brake pads from the rotor. In that case, the friction generated by the pads’ continued contact with the rotor will result in excessive heat, wear, and drag, which may cause the brake calliper to get stuck.
A stuck brake calliper may result in several issues, such as:
Brake pad wear may occur unevenly, resulting in one pad wearing out more quickly than the others. This may lead to decreased braking effectiveness, increased stopping distances, and more frequent pad replacement.
Reduced fuel efficiency: A dragging wheel caused by a stuck brake calliper may increase fuel consumption and lower fuel efficiency.
Reduced braking capacity: A stuck brake calliper may lower the braking power of the damaged wheel, making it more difficult to stop the automobile swiftly in an emergency.
Overheated brakes: A stuck brake calliper may result in excessive heat accumulation in the braking system, causing the brake fluid to boil and lowering the overall car’s stopping power.
To guarantee your safety and the safety of other road users, it’s critical to have a trained technician examine and fix any suspected stuck brake callipers as soon as possible. The brake pedal is on par with, if not above, the importance of the gas pedal in a vehicle. Because they allow you to bring your car to a halt in a relatively short time, brakes are the first step towards making a safe and dependable vehicle. Therefore, if you have seen that your brakes have started to get sticky, you will likely need to inspect your brake callipers.
What are some solutions for a brake calliper that will not move? A sticking brake calliper may be fixed in seven simple stages, which are as follows:
- Jack up the car so you can get to the wheels.

How to Remove and Replace a Sticking Brake Caliper in 7 Easy Steps
Brake callipers are responsible for applying pressure to the brake pad, which slows the wheel’s rotational speed and, by extension, the vehicle. Callipers move the brake pad back and forth using sliding pins and grooves in the calliper. It should be a simple and smooth move, but this groove is often congested with road debris or grease buildup, which requires you to clean the callipers before a significant problem occurs.
Before beginning any activity, you must ensure that you have all the necessary instruments for the job ready and waiting for you. After that, you will save time looking for another tool to do any necessary repairs.
You will need the following items to repair your brake callipers if they are sticking:
- Car or Tire Jack
- Lug Wrench
- Grease for the Calipers and the Brakes
- Socket Wrench Set
- Rags
- Brake Cleaner
1. Jack up the car so you can get to the wheels
First, you need to determine which brakes you believe are stuck. These are the wheels that need to be retrieved from the ground first. To begin, follow the guidelines provided by the manufacturer of the jack for positioning the jack beneath the vehicle or wheel.
While working on the brakes, it is essential to protect yourself by positioning chocks behind the other wheels of the vehicle. This will prevent the car from moving while you are repairing it.
2. Remove the Wheel
Remove the wheel using the lug wrench in the next step. Put all of the bolts in the immediate area, at a spot that is easy to recall and from which they cannot roll away. Please take off the wheel by hand, and place it on the ground next to you.
3. Purify the brake pads
You should no longer have any trouble reaching the brakes. Applying a heavy-duty brake cleaner to the exposed brake pads and linings per the instructions on the product’s packaging requires you to use a brake cleaner such as CRC Brakleen Brake Part Cleaner.
Dirt from the road, grease, oil and any other pollutants that have made their way into your brakes will be removed as a result of doing this. Cleaning the brake pads will reduce sticking and screeching, allowing your vehicle to be driven in a manner that is both more secure and more quietly.
4. Remove the brake pads and calliper
Remove the callipers and pads from the brakes now that they have been cleaned. To do this, remove the bolts from the callipers and take them away from the bracket holding them in place. This provides access to the brake pads, which may be removed by hand once you have done so.
Spend a few seconds throughout your day checking your car’s brake pads. According to what is stated in another of my articles, they need to be changed if their thickness is less than a quarter of an inch, which is equivalent to around three millimetres. When you drive with brake pads that are too thin, you will hear more screeching and have a greater chance of your brakes locking up.
5. Cleaning the Brake Caliper Itself
After that, remove any old oil or lubricants that may have built up on the brake calliper and any dust that may have accumulated there. To thoroughly clean the calliper, use a brake cleaner with your cloth.
It is important to note that the calliper pins and bolts each have a rubber boot. Have a glance over them to see if there are any rips. Damage to a rubber boot, which often happens when mechanics change the brake pads, might allow too much buildup and debris into your callipers. This can cause your brakes to become less effective. If you discover a damaged or torn calliper boot, you must repair this immediately.
If these components’ corrosion or dirtiness makes cleaning them impossible, you may replace them. If they have deteriorated to such an extent, the whole brake calliper may need to be replaced.
6. Lubricate the slides, pins, and callipers of the brakes
When your calliper has reached the point where it is nearly as good as new, it is time to re-grease it. Consider using a lubricant specifically for callipers, such as the Permatex Ultra Disc Brake Caliper Lube 24110. This is a fantastic method for cleaning the rear of brake pads, calliper pins, and hardware.
Some people who do home repairs choose to use a generic lubricant, such as white lithium grease. This is not designed only for use with callipers, but the price is much lower.
When lubricating the brake callipers, it is essential to ensure that all nuts, pins, slides and pistons get enough grease. You want each surface to be gently coated so that it is protected from any more dust and so that sliding can be done smoothly.
7. Put the Calipers, Brakes, and Wheels Back On
After ensuring everything is clean and lubricated, the brake calliper may be reinstalled into its bracket. Reinsert the calliper bolts using the appropriate threading. You can get the first tightening done by hand, but then you need to switch to using your socket wrench. It is essential to avoid overtightening these bolts. Cracking may occur if anything is over-tightened, which can cause damage to your brakes, pads, and callipers.
After that, put the brake pads back in place and double-check that they are correctly fastened. After you have reattached the tyre to the axle, tighten the lug nuts. Remember that overtightening the lug nuts might damage the wheel, so take care not to do so. Check the owner’s handbook for your vehicle to determine the appropriate level of tightness.
You would need to repeat these methods for each wheel and brake calliper if more than one of the brakes was stuck.
Other potential solutions to the problem of sticking brake callipers
Any sticking that may be happening may often be removed by giving the brake callipers, pins, and pads a thorough cleaning. Nevertheless, a few issues still need to be more readily resolved. In many cases, a more severe problem requires the diagnostic expertise of an experienced technician. If your brakes are still sticking, a handful of additional possible issues might happen with your vehicle.
Your Emergency Brake Has Severed Off Completely
Your emergency or parking brake may be connected to the callipers on the back of your wheels. In this scenario, sticking your brakes might result from a worn-out brake line that exerts an inappropriate amount of force on your callipers. If such is the case, the tube for the emergency brake will need to be replaced.
Leaking or torn brake hose
If your brake hose is damaged, the brake fluid will continue to flow into the brakes but will not exit. When everything is functioning as it should, the liquid should be able to rush back to the master cylinder.
You will need a complete vehicle jack to attempt to repair this. First, remove the load from the wheels and start using the brakes. This may realign the hose to get the desired flow. However, it only sometimes works. You will be required to replace the brake hose if it does not.
Now Is the Time to Get Those Stuck Brakes Unstuck
You should now be able to disassemble your brakes and callipers and clean them thoroughly. When you find a free afternoon and a little space in your garage, it is time to go to work. Be careful to proceed in the sequence laid out for you, and keep track of your tools and bolts as you go.
When items are put back together incorrectly after being taken apart for house repairs, this is one of the most common reasons things go wrong. If you are anxious, think about recording yourself on video or snapping photographs as you go. This will ensure that you are aware of where everything should be placed and will also allow you to evaluate the degree to which your cleaning efforts were successful.
