Emergency brake is stuck
can be a scary and potentially dangerous experience. There are several causes and solutions to your car’s stuck parking brake depending on the condition and type of brake system.
In this post, you will learn the popular causes and solutions to stuck emergency brakes.
JUMP TO TOPIC
What Is the Major Cause of a Stuck Emergency Brake?
The major cause of a stuck emergency brake is corrosion. As the most common cause of this issue, corrosion will hinder the free movement of some of your car’s braking system components. For instance, corrosion can make components like linkages and cables irregular.
The irregular surfaces can bind or stick to each other. Also, rust restricts the movement of various brake components. It is this limited movement that can prevent your brake from disengaging when you release the lever. For example, a corroded cable can become stiff or even kinked making it difficult for the brake to release.
Can you drive with a stuck parking brake? The answer is, no. It is not advisable since it poses serious safety risks. For instance, a stuck parking brake affects your car’s handling. As a result of a stuck emergency brake, your vehicle may be involved in an accident.
A stuck brake can result in uneven braking. This will result in uneven braking resulting in instability and compromised handling especially when making sudden maneuvers.
Besides, when you have a stuck brake, it causes accelerated wear and tear to your car’s brake components. Ultimately, you will have to make regular repairs to the brake system. Also, a stuck brake generates excess heat in the brake system. When this happens, the heat boils the brake fluid.
In turn, it will reduce the braking efficiency. Moreover, the excess heat the stuck brakes generate when moving can damage brake components.
Freezing Weather Can Make Your Car’s Braking System Stick
If it is winter, another plausible reason for your stuck brake is freezing weather. The extreme cold can get the brake stuck since it can freeze the cables and linkages. Once moisture gets into the linkages, it freezes and expands.
When this happens, it can cause the linkages and cables to be stuck making it difficult to disengage the parking brake. Freezing will likely make your car’s braking system stick if it has drum brakes. The explanation is brake shoes in drum brakes are prone to moisture contact compared to brake pads found in disc brakes.
Freezing effectively restricts the movement of your car’s braking components by gluing them together. Therefore, when you try to disengage the emergency brake, the ice grip on the frozen components will prevent it from releasing.
Rigid Application Can Result in a Stuck Brake System
Another cause of stuck emergency brakes is rigid application. When you use too much force, it can make the brake stick because of the way the brake system operates. The moment you use too much force to engage the parking brake, you can cause the components in your car’s braking system to bind.
In addition, using too much force can damage or misalign the brake system. As a result, the components may be unable to return to their positions when you release the brake.
For example, a rigid application can misalign your car’s brake pads or shoes with the brake drum or rotor. When this happens, it can result in uneven pressure and contact making the parts stick or bind.
Furthermore, using too much force to engage your car’s parking brake can strain the brake cable causing it to snap or even become tangled. If you have a damaged cable or linkages, it will prevent your car’s brake from disengaging.
Failing Brake Caliper: The Hidden Culprit Behind Stuck Brake
If your car has a malfunctioning caliper, it can get the parking brake stuck on rotor. This will happen since a malfunctioning caliper will prevent your car’s brake pads from releasing from the rotor. As a result, it will be difficult to disengage the emergency brake.
With time, your car’s calipers can corrode and seize. This will eventually prevent your car’s piston in the caliper from moving making it difficult to release the brake pads. Also, if the seal to your calipers is faulty, it can result in brake fluid leaks. This will result in a malfunctioning caliper that can cause your car’s hand brake to stick.
Faulty Wheel Cylinder Can Jam Your Emergency Brake
Another reason your car’s brake may jam is because of a faulty wheel cylinder. This will happen if the wheel cylinder leaks fluid because of internal damage or worn seals. When it happens, it affects the hydraulic pressure in the braking mechanism. As a result, it may lead to an incomplete release of the brake shoes from the drum.
Once the wheel cylinder fails to release fully, the brake shoes will remain in contact with the drum causing brake problems. It is this partial engagement that results in excess friction and heat when driving which results in overheating and potential binding. The binding will prevent the brake from disengaging when you try to release it.
Extended Use of Parking Brake: The Hidden Price of Neglect
If you leave the parking brake engaged for too long, the emergency brake can stick. This will happen as moisture accumulates around your car’s brake components creating rust on its drum or rotor and the brake shoes or pads. The rust will bind the components preventing smooth movement.
In addition, the pressure on the brake components together with the extended engagement can breakdown lubricants meant to facilitate smooth movement. As a result, the lack of lubrication leaves the brake components prone to sticking when engaged for a long time.
What Is the Best Solution to a Stuck Parking Brake?
The best solution to a stuck parking brake is gently disturbing the brakes manually. By disturbing your car’s brakes manually you can solve the issue by dislodging any corrosion or binding. To disturb the brakes, you need to use controlled force to free the stuck components.
By gently operating the brake, you can distribute dried lubricant. As a result, it can decrease the friction between the various components eventually disengaging the brake. This is one of the quickest ways how to disengage parking brake manually.
The process includes pressing and releasing the brakes several times. Also, you can shift your car into drive and reverse several times to slightly move the vehicle back and forth. This is an easy way of dislodging rust from your brake system.
In addition, you can visually check for corrosion on your car’s parking brake. Once you establish rust surrounding the cable or other components of the brake system, you can try scrapping it off or replacing affected components. This will release your car’s stuck emergency brakes.
Warming Up Your Car Can Release a Stuck Emergency Brake
In cold weather, warming up your car can release a frozen parking brake. By turning your car on, the heat generated by the engine will thaw ice and decrease the effects of cold temperature on your car’s brake components. This involves starting your car and letting the engine run for several minutes to warm everything up.
Besides thawing ice on your car’s brake components, warming up your car will help metal components expand. This is going to decrease the friction between components that are causing your brake to stick. Eventually, it will make it possible to disengage the brake.
Furthermore, letting your car warm up makes it easy for the brake lubricants to flow. This will aid the smooth movement of your car’s brake components solving the issue you have with your car.
Lubrication Can Break the Shackles of a Stuck Brake
Another solution is lubrication. When you lubricate brake components such as levers, linkages, and cables with the right lubricant, you help them move freely. Lubrication will reduce the friction between your car’s moving brake components making sure they do not stick or bind.
Also, when you lubricate the components of the handbrake, you prevent corrosion or rust. In addition, lubricants with low freezing points assist in thawing ice. This restores the proper functioning of your car’s emergency brake mechanism.
As well, lubrication helps clean dirt and debris in brakes. If your car’s brake components are not severely damaged, you can use lubrication to restore their function.
A Professional Mechanic Can Rescue Your Stuck Brake Woes
If you have tried different methods and you are still unable to release the stuck brake, you should consult a professional mechanic. Do not risk damaging your car, towing your car to a professional mechanic is a safer option.
Taking your car to a professional eliminates guesswork since the expert can pinpoint the cause of this issue. A professional mechanic has the tools and expertise to diagnose and apply the right solution. In addition, the professional knows how to release parking brake with broken cable.
Caliper Service Can Set Your Stuck Parking Brake Free
You can also service faulty calipers to deal with this issue. For this solution, you will need a professional mechanic to inspect the calipers for misalignment, damage, or wear. If debris accumulation or lack of lubrication is to blame, the service will involve cleaning the components and using the right lubricants for smooth movement.
In case your car has a misaligned caliper or its internal components are damaged, your mechanic will make the necessary repairs and adjustments. This will include replacing worn parts, repositioning the caliper, or addressing issues that make it stick. That is how to release stuck brakes.
Repairing the Release Mechanism Can Restore Your Stuck Brake
Another solution is repairing a faulty release mechanism for the parking brake. This will address the issues making your car’s emergency brakes not function as they should. To do this correctly, you need a mechanic to inspect the release mechanism to identify the underlying issues of the emergency brake stuck up.
The professional will inspect the lever, linkages, and cables of your emergency brake. Once the mechanic establishes the issue, they will make the necessary changes to restore the smooth movement of the release mechanism.
A professional offers a comprehensive solution since they can address different problems with the release mechanism of the handbrake.
