Bleeding brakes is an important maintenance job to keep your car in good working order. The brake system is a closed system, which means little air or other contaminants can enter the system. Over time, air and other contaminants can build up in the brake system and cause damage. If you don’t bleed your brakes, the following problems can occur:
1. Reduced Braking Power
The most common symptom of not bleeding your brakes is reduced braking power. Brake fluid is designed to transfer the force from the brake pedal to the wheel brakes. If air is introduced into the system, the fluid becomes less efficient and the force from the pedal is reduced. This can lead to a feeling of “sponginess” when pressing the pedal and a longer stopping distance.
2. Damaged Brake System Components
When air is allowed to enter the brake system, it can cause damage to the various components. The brake system consists of a master cylinder, calipers, wheel cylinders, and hoses. Air in the system can cause corrosion or wear on the components, leading to costly repairs. In some cases, the entire system may need to be replaced.
3. Brake Fluid Leakage
If air is allowed to enter the brake system, it can cause the brake fluid to leak. The brake system is designed to be a closed system and any leakage will lower the level of fluid in the system. This can lead to further damage to the system and loss of braking power.
4. Poor Brake Pedal Response
The brake system is designed to provide a smooth and consistent response when pressing the brake pedal. If air is allowed to enter the system, the response can become unpredictable. This can lead to a feeling of “jerky” braking or even a complete loss of braking power.
Frequently Asked Questions
1. What happens if I don't bleed my brakes?
If you don’t bleed your brakes, the following problems can occur: reduced braking power, damaged brake system components, brake fluid leakage, and poor brake pedal response.
2. How do I know if I need to bleed my brakes?
If you experience any of the symptoms mentioned above, you should have your brakes checked by a professional mechanic. They can determine if you need to bleed your brakes.
3. How often should I bleed my brakes?
Most vehicle manufacturers recommend that you have your brakes checked and bled every two years or 20,000 miles. If you use your vehicle frequently or in extreme conditions, you may need to have your brakes checked and bled more often.
4. How long does it take to bleed brakes?
The amount of time it takes to bleed brakes can vary depending on the type of vehicle and the condition of the brake system. Generally, it can take anywhere from 30 minutes to an hour.
5. Is it dangerous to not bleed your brakes?
Yes, it is dangerous to not bleed your brakes. Air in the brake system can cause reduced braking power, damaged components, brake fluid leakage, and poor brake pedal response. This can lead to an accident or injury.
6. Can I bleed my brakes myself?
Yes, you can bleed your brakes yourself if you have the proper tools and knowledge. However, it is always best to have a professional mechanic check and bleed your brakes to ensure the job is done correctly.
7. Is it safe to drive with air in the brake system?
No, it is not safe to drive with air in the brake system. Air in the system can reduce braking power and cause other damage, which can lead to an accident or injury.
8. How much does it cost to have my brakes bled?
The cost of having your brakes bled can vary depending on the type of vehicle and the condition of the brake system. Generally, you can expect to pay anywhere from $50-$150 for a brake bleed.
9. What type of fluid should I use for my brakes?
Brake fluid is designed to be compatible with the specific type of brake system in your vehicle. You should always check your vehicle’s owner’s manual to determine which type of fluid is recommended for your vehicle.
10. What causes air to get into the brake system?
Air can enter the brake system through a leak in a brake line or hose, or when the brake system is opened up for repair. It is important to always bleed the brake system after any repairs are made to ensure that no air has entered the system.
11. Do I need to bleed my brakes after replacing the pads?
Yes, it is recommended to bleed your brakes after replacing the pads. This will ensure that the brake system is free of any air or other contaminants.
12. Can I use any type of brake fluid?
No, you should not use any type of brake fluid. Brake fluid is designed to be compatible with the specific type of brake system in your vehicle. You should always check your vehicle’s owner’s manual to determine which type of fluid is recommended for your vehicle.
13. How often should I change my brake fluid?
Most vehicle manufacturers recommend that you have your brake fluid changed every two years or 24,000 miles. If you use your vehicle frequently or in extreme conditions, you may need to change the fluid more often.
14. What happens if I use the wrong type of brake fluid?
Using the wrong type of brake fluid can cause damage to the brake system and can lead to reduced braking power. It can also cause corrosion and wear on the components, leading to costly repairs.
15. Can I mix different types of brake fluid?
No, you should not mix different types of brake fluid. Mixing brake fluid can cause damage to the brake system and can lead to reduced braking power.
16. How do I know if I have air in my brake system?
If you experience any of the symptoms mentioned above, you should have your brakes checked by a professional mechanic. They can determine if you have air in the brake system.
17. What is the best way to bleed my brakes?
The best way to bleed your brakes is to use a vacuum pump. This will quickly and efficiently remove any air or other contaminants from the brake system.
18. Can brake fluid go bad?
Yes, brake fluid can go bad over time. Brake fluid can absorb moisture from the atmosphere, which can cause corrosion and other damage to the brake system. It is important to check the level and condition of the brake fluid regularly.
19. How do I know when my brake fluid needs to be changed?
Most vehicle manufacturers recommend that you have your brake fluid checked and changed every two years or 24,000 miles. If you use your vehicle frequently or in extreme conditions, you may need to have your brake fluid checked and changed more often.
20. What are the signs of a failing brake system?
The signs of a failing brake system can include reduced braking power, a spongy feeling when pressing the pedal, a longer stopping distance, and poor brake pedal response. If you experience any of these symptoms, you should have your brakes checked by a professional mechanic.
