The brake cylinder is an integral part of the vehicle’s hydraulic braking system, which converts the hydraulic pressure generated by the brake pedal into mechanical force to initiate braking.
The brake cylinder is responsible for applying pressure to the brake shoes or pads in contact with the rotating brake drum or disc to create friction that slows or stops the vehicle.
Brake cylinders have two types: brake master cylinders and brake wheel cylinders.
In a drum brake system, brake wheel cylinders are located on each wheel. They have a piston inside that pushes the brake shoes when hydraulic pressure is applied. On the other hand, brake master cylinders are located on the brake pedal and are responsible for generating the hydraulic pressure distributed to each wheel cylinder.
Overall, brake cylinders play a vital role in ensuring safe vehicle deceleration and stopping. If there is a problem with brake cylinders, such as a leak or piston failure, it can cause problems with braking performance and should be repaired or replaced promptly.
Why do brake cylinders fail?
Brake cylinders can fail for several reasons, including:
1. Wear and tear: Over time, the brake cylinder can wear down and become damaged due to repeated use, exposure to heat and friction, and other factors.
2. Corrosion: Brake cylinders can corrode due to exposure to moisture and salt from the road. This can cause the cylinder to become weak and brittle, leading to failure.
3. Contamination: If dirt, debris, or other contaminants get into the brake cylinder, they can damage the seals and cause leaks.
4. Overheating: Brakes can generate a lot of heat during use, and if the cylinder gets too hot, it can cause the seals to break down and fail.
5. Improper maintenance: Lack of proper maintenance can lead to brake cylinder failure. Regular brake fluid changes and inspections can help prevent issues with the brake cylinder.
Overall, regular maintenance and care can help prevent brake cylinder failure and ensure safe and reliable braking performance.
Can you drive with a broken brake cylinder?
The answer is absolutely No, you should not drive with a broken brake cylinder. The brake cylinder is an essential component of your vehicle’s braking system, and if it is not functioning correctly, it can compromise your ability to stop the vehicle safely.
The brake cylinder is responsible for converting the pressure from the brake pedal into hydraulic pressure, which then pushes the brake pads or shoes against the brake rotors or drums. If the cylinder is broken, it may leak brake fluid, which can result in a loss of hydraulic pressure, making it difficult to stop the vehicle or causing the brakes to fail entirely.
If you suspect that your brake cylinder is broken or malfunctioning, you should have it repaired or replaced as soon as possible by a qualified mechanic. Driving with a broken brake cylinder can be dangerous and increase the risk of an accident.
How do I choose a master cylinder?
Choosing a master cylinder depends on several factors, including the type of brake system you have, the size and weight of your vehicle, and the type of driving you’ll be doing. Here are the steps to follow when choosing a master cylinder:
1. Determining the brake system type: There are two types of brake systems, drum brakes, and disc brakes. You will need to choose a master cylinder that is compatible with your brake system. Disc brake systems require a master cylinder with a larger bore size than drum brake systems.
2. Determining the size of your vehicle: Larger vehicles will require a master cylinder with a larger bore size. The bore size of the master cylinder determines the amount of fluid that is displaced with each stroke of the pedal. A larger bore size means more fluid is displaced, which is necessary for larger vehicles.
3. Determining the type of driving you’ll be doing: If you will be doing mostly street driving, a master cylinder with a smaller bore size is appropriate. If you will be doing performance driving or racing, a larger bore size is necessary to provide more brake pressure.
4. Considering the type of brake fluid: As we all know that different types of brake fluid have different viscosity and compressibility. So we have to make sure that the master cylinder you select is compatible with the type of brake fluid you will be using.
5. Checking for compatibility with your brake booster: If you have a brake booster, make sure to choose a master cylinder that is compatible with it. The master cylinder and brake booster must work together to provide proper braking performance.
6. Checking for compatibility with your brake booster: If you have a brake booster, make sure to choose a master cylinder that is compatible with it. The master cylinder and brake booster must work together to provide proper braking performance.
7. Consulting with a professional: If you are uncertain about which master cylinder to choose, consult with a professional mechanic or brake cylinder manufacturer. They can help you choose the right master cylinder for your specific vehicle and driving needs.
How much does a brake cylinder cost?
The cost of a brake cylinder depends on several factors, such as the maker and model of the vehicle, the type of brake cylinder, and where you purchase it from.
In general, the cost of a brake cylinder can range from around $30 to $200 or more. However, some high-end or specialized brake cylinders may cost even more. And please note that the cost of the brake cylinder is only one part of the total cost of repairing or replacing the brakes. We also have to consider the cost of labor, any additional parts or components that need to be replaced, and other related fees or taxes.
If you’re looking to buy brake cylinders, it’s a great idea to look around and compare prices from different sources, like local auto parts stores or online retailers/manufacturers. You should also consult with a professional mechanic/manufacturer to make sure that you’re getting the right part for your vehicle and that it’s installed correctly.
