What happens if I never replace my brake rotors?

If you never replace your brake rotors, you may run into some serious problems that can affect your driving safety and vehicle performance. Here are some of the consequences of not replacing your brake rotors:

Deteriorated braking performance: As brake rotors wear, their friction surface becomes thinner, resulting in less effective braking. This increases stopping distances and makes your vehicle less safe, especially in emergency situations.

Brake judder and noise: Unevenly worn or damaged brake rotors may cause your vehicle to judder when braking, or even make unusual noises such as squealing or metal rubbing when braking. These noises are not only disturbing, but can also indicate more serious problems.

Accelerated brake pad wear: Damaged brake rotors may accelerate brake pad wear, resulting in more frequent brake pad replacements and increased maintenance costs.

Deformed or warped brake rotors: As brake rotors become thinner, they are more likely to overheat and deform or warp. This can cause vibrations and uneven braking force distribution when braking, further reducing braking performance.

Cracked or burst brake rotors: If brake rotors are worn to their limits, they may crack or burst under high temperatures and pressures. This will not only cause the brakes to fail, but may also cause the vehicle to lose control, increasing the risk of an accident.

Damage to other brake system components: Severely worn or damaged brake discs may cause additional stress and damage to the brake calipers, brake pads and other brake system components, resulting in higher repair costs.

Increased fuel consumption: Due to reduced braking performance, greater force may be required to slow down or stop the vehicle, which may increase fuel consumption.

Potential safety risks: Damage to the brake disc may cause the brake system to be unable to provide sufficient braking force in an emergency, increasing the risk of accidents.

To avoid these problems, it is recommended to regularly check the wear of the brake disc and replace it if necessary. Generally, the replacement cycle of the brake disc is 60,000-80,000 kilometers, but this cycle varies depending on driving habits, vehicle type and usage environment. If you notice any of the above problems, you should consult a professional auto repair technician for inspection and repair as soon as possible.

In addition to the brake disc, what other brake system components need to be checked regularly?

The maintenance of the brake system is essential to ensure the safety performance of the vehicle. Here are some inspection and maintenance recommendations for key components:

Brake pads: Brake pads are the most critical safety parts in the brake system and need to be checked regularly for thickness and wear. New brake pads are about 1.5 cm thick. When they are worn to only one-third, or about 0.5 cm, they should be replaced. In addition, if there is an abnormal noise or tremor when braking, it may also indicate that the brake pads need to be replaced.

Brake discs: Brake discs are also wear parts, and they usually need to be replaced after two brake pads have been replaced. The degree of wear of the brake disc can be determined by visual inspection or measuring its thickness with professional tools. If there are dents or grooves on the surface of the brake disc, the disc may need to be replaced.

Brake fluid: Brake fluid absorbs moisture from the air, causing performance degradation. It is recommended to replace the brake fluid every 50,000 kilometers or every two years to ensure the normal operation of the brake system.

Brake lines: Brake oil lines are easily overlooked components, but they will age over time. Check the brake oil lines for signs of cracks, expansion or leakage, and replace damaged lines in time.

Brake booster: For vehicles equipped with a brake booster, the working condition of the booster should be checked to ensure that the brake booster can provide sufficient auxiliary force.

Brake pedal: Check the free travel of the brake pedal to ensure that the brake pedal is within a reasonable range. If the free travel is too large or too small, it needs to be adjusted.

Parking brake: Check whether the handbrake or electronic parking system can effectively lock the vehicle.

Tire inspection: Since the grip of the tire directly affects the braking effect, the wear and tire pressure of the tire should be checked regularly.

Cleaning and lubrication: Regularly clean the various components of the brake system, such as the brake caliper, brake cylinder, etc., and apply an appropriate amount of anti-noise glue and lubricant.

Brake system adjustment: Regularly check the adjustment of the brake system, including the travel of the brake pedal and the working condition of the brake caliper, and adjust it as needed.

Remember that the maintenance and inspection of the brake system should be performed by professional technicians to ensure safe and correct operation. If you are not sure how to perform these inspections, it is recommended to consult a professional car repairman.

In addition to brake discs, what other brake system components need to be checked regularly?

In addition to brake discs, several other critical components of the braking system should be checked regularly to ensure optimal performance and safety. Here are some of the key components that require regular inspection and maintenance:

Brake Pads: These are the friction materials that press against the brake discs to create stopping force. They wear out over time and need to be replaced when they reach a certain thickness or show signs of excessive wear.

Brake Fluid (Brake Oil): The hydraulic fluid that transmits pressure from the master cylinder to the brake calipers or wheel cylinders. It should be checked for level, contamination, and moisture content, and replaced according to the vehicle manufacturer’s recommendations.

Brake Calipers: These hold the brake pads and apply pressure to the discs. They should be checked for proper operation, leaks, and wear. The caliper pistons may need to be cleaned or replaced if they seize or fail to retract properly.

Brake Hoses and Lines: The flexible hoses and metal lines that carry brake fluid from the master cylinder to the calipers. They should be inspected for cracks, leaks, swelling, or signs of deterioration.

Master Cylinder: The component that converts the force applied to the brake pedal into hydraulic pressure. It should be checked for leaks and proper function.

Wheel Cylinders (for drum brakes): These apply pressure to the brake shoes in drum brake systems. They should be checked for leaks and proper operation.

Brake Fluid Reservoir: The container that holds the brake fluid. It should be checked for cracks, leaks, and the correct fluid level.

Emergency Brake Cable (for cable-operated parking brakes): The cable that connects the parking brake lever to the rear brakes. It should be checked for proper adjustment, wear, and corrosion.

ABS System Components: If your vehicle is equipped with Anti-lock Braking System (ABS), the ABS control module, sensors, and wiring should be checked for damage and proper function.

Brake Warning Light Switch: This switch, often located on the brake pedal arm, should be checked to ensure it’s functioning correctly and not causing false warnings.

Proportioning Valve: Some vehicles have a proportioning valve that regulates brake pressure between the front and rear brakes. This should be checked for proper operation.

Brake Rotor Sensor: Some modern vehicles have sensors on the brake rotors that monitor wear and communicate with the vehicle’s computer system.

Regular inspection and maintenance of these components can help prevent brake failure and ensure the safety of your vehicle. It’s essential to follow the vehicle manufacturer’s recommended maintenance schedule and have any issues addressed by a qualified technician.
