Notes When Polishing Car Brake Discs Safely and Effectively

Automotive brake disc is an indispensable component in the vehicle's braking system. It plays an important role in slowing down and stopping the vehicle when necessary.

In a car, the brake system plays an extremely important role, directly affecting safety and operating performance. Brake maintenance and maintenance is essential, in which, smoothing the brake disc surface is one of the most important jobs. Below are the necessary notes when performing this job.

Brake disc surface finishing – why is it important?

Brake disc surface finishing is not only for improving braking performance but also has many other benefits:

• Eliminates noise and vibration: Uneven brake disc surfaces can cause noise and a vibrating feeling when braking. Smoothing helps create a uniform contact surface between the brake pads and the brake disc.
• Extend the life of the brake system: According to experts, smoothing the brake disc surface helps reduce the wear rate of other parts in the brake system, thereby extending its service life.
• Thickness balancing: Smoothing helps balance the thickness of the brake disc surface, ensuring stable operation of the system.

Signs that the brake disc needs to be polished

Drivers should pay attention to the following signs when deciding to bring their car to have its brake discs polished:

• Brake discs vibrate and make noise: If you feel a vibration or hear a strange noise when you apply the brakes, this could be a sign that the disc surface is damaged.
• Unreal brake feel: If you find it difficult to control the braking force, the disc surface may be uneven.
• Signs of wear: Check the brake disc surface for signs of heavy scratches or dirt buildup between the pads and disc.

Safe brake disc polishing method

There are two main methods for polishing brake discs:

• Direct Screeding: This method requires highly skilled technicians and specialized equipment. The process simulates the movement of wheels during daily operation, helping to ensure high accuracy in surface smoothing.
• Disassemble and smooth: This is the more common method in auto garages. After removing the brake disc, the mechanic will use a lathe to smooth it. Although this method creates a fairly flat surface, it is difficult to ensure uniform thickness on both sides of the disc.

Important notes when performing brake disc polishing

The four main notes include:

• Don't take smoothing lightly: Some drivers think that replacing brake pads is enough. However, without smoothing the discs, the system can still quickly deteriorate.
• Frequency of refinishing: According to recommendations from technicians, each brake disc should only be refinished a maximum of 3 times during its lifetime. The time between refinishing should be spaced from 2 to 3 years depending on the level of use.
• Regular inspection: To ensure safety, drivers should check the brake system regularly, especially after every 20.000 km of travel or when detecting any unusual signs.

Resurfacing your car's brake discs not only improves performance and safety, but also extends the life of your brake system. Drivers need to pay attention to the signs of maintenance and choose the right method to do this job most effectively. Always remember, a safe car starts with a well-maintained brake system!

FAQ – Frequently Asked Questions

1. How does brake disc finishing affect braking performance?

Brake disc surface finishing creates a uniform contact surface between the brake pad and the brake disc, improving braking force transmission by up to 30%. This reduces braking reaction time and increases safety.

2. How often should brake disc resurfacing be performed?

Depending on the conditions of use, it is generally recommended to resurface the brake discs every 20.000 km or when signs of abnormality are detected. This helps maintain optimal performance of the braking system.

3. How much does it cost to resurface a brake disc?

The cost of resurfacing brake discs ranges from 500.000 to 1.500.000 VND depending on the garage and the method of implementation. This is a reasonable investment to prolong the life of the brake system.

4. Is it necessary to replace the brake pads when resurfacing the disc?

It is not necessary to replace the brake pads when resurfacing the disc, but if the brake pads are worn excessively (less than 3 mm), they should be replaced to ensure performance and safety.

5. What are common mistakes when smoothing brake discs?

Common mistakes include not checking the thickness of the disc before screeding, over-screeding reducing the safe thickness below 5mm, or not cleaning the surface after completing the process.
