A brake is an important safety feature in a car. Over time the brake pads and rotors accumulate dust and contaminants. With time, a brake becomes less effective and can pose serious safety concerns. That’s why brake burnishing and cleaning becomes essential for proper brake performance.
While burnishing is a process to improve the braking performance, cleaning is equally important to eliminate accumulated dust on the brakes. Besides, brake pad burnishing and cleaning are crucial in electric cars due to the regenerative braking process. Let’s go through more details about the brake burnishing procedure and cleaning of brake components.
What Is Brake Burnishing?
Brake burnishing, also known as brake bedding or brake conditioning, is a process to enhance the performance and longevity of brake pads and rotors. It involves subjecting the brakes to a series of controlled stops to generate heat and transfer a thin, even layer of brake pad material onto the brake rotor surface.
This process helps to improve brake pad and rotor compatibility. However, if the brake burnishing isn’t done correctly, the rotors and pads can wear out and become a reason for squealing noises from brakes.
During burnishing, the brake pads and rotors undergo a cycle of heating and cooling. It ensures that the pads make full contact with the brake rotor surface. This helps to minimise the chances of uneven brake pad material deposition, known as brake pad glazing. Moreover, brake pad glazing can reduce braking efficiency and lead to noise and vibration. That’s why one must learn the process of brake burnishing.
Brake Burnishing Procedure
Burnishing of brake pads can significantly reduce the squealing noises. If you don’t burnish, you may witness the signs of bad brake pads such as spongy brakes or noises. Therefore, you must follow these steps for brake burnishing.
- Accelerate the car from 60 km/h to 80 km/h on a straight road
- Apply consistent brakes to bring the speed to 20 km/h
- Repeat the process for five to six times
Why Is Brake Burnishing Important?
After the replacement of brake pads and rotors when they wear out, you must complete the brake burnishing process to ensure their optimum performance. It has the following importance:
- It improves braking performance, shortens stopping distances and provides better overall safety.
- Burnishing can reduce the likelihood of uneven contact between the pads and rotors, reducing noise.
- It helps prevent brake pad glazing, a condition where the surface of the brake pad becomes hardened and smooth due to excessive heat.
- Properly burnished brakes tend to last longer because they wear more evenly, reducing brake maintenance costs.
Brake Cleaning
Over time, car brakes accumulate dust. Brake cleaning is a maintenance task that involves removing brake dust, dirt, grime and other contaminants from the brake components to ensure optimal braking performance and longevity.
While the dust is caused by friction and driving habits, you must follow the brake dust prevention tips to avoid it. Here’s the process to clean and maintain the brakes after burnishing.
Brake Cleaning Process
The brake cleaning process is essential for maintaining performance and overall safety. Here’s how to clean brake dust:
- Get a brake cleaner solution, a jack stand, a lug wrench, a wire brush or steel wool and a clean cloth.
- Park your car on a flat surface and engage the parking brake.
- Ensure good ventilation in your work area as brake cleaner fumes can be toxic. Lay down a cloth or cardboard to catch any drips or overspray.
- Loosen the lug nuts on the wheels before jacking up the vehicle. Once raised, remove the wheels to access the brakes.
- Before cleaning, visually inspect the brake components for any signs of wear, damage or leaks. Address any issues as necessary.
- Spray brake cleaner onto the brake calliper, rotor and pads. Use a wire brush or steel wool to scrub away brake dust, dirt and grime.
- Pay special attention to areas where brake components meet, as buildup in these areas can cause noise and reduced performance.
- After scrubbing, use clean cloths to wipe away excess cleaner and dirt. Ensure all surfaces are clean and dry before reassembly.
- Put the wheels back on and tighten the lug nuts securely. Lower the vehicle and test the brakes by gently pressing the pedal while stationary to ensure proper function.
Why Is Brake Cleaning Important?
Brake dust can cause jamming between the components. It can become one of the main reasons for brake overheating and may cause brake failure. That’s why brake burnishing and cleaning become essential. Here is the importance of brake cleaning:
- Brake dust and debris can accumulate on brake components, affecting their performance and reducing stopping power.
- Dirty brakes can lead to brake noise, vibration, and poor pedal feel. Cleaning removes brake dust, dirt, and grime, allowing the brakes to operate smoothly and quietly.
- The importance of cleaning brake components is that it can help identify early signs of car brake problems, wear or damage, such as worn brake pads or leaking brake fluid.
- It gives you an idea of early car brake repair signs and saves you from a major setback.
- Dirty brakes can increase rolling resistance, reducing fuel efficiency. By keeping brake components clean and well-maintained, you can help maximise fuel economy.
FAQs
Is it necessary to Burnish your brakes?
Yes, brake burnishing can shape the rotors and pads to work properly and reduce friction.
Is brake cleaning service necessary?
Yes, brake cleaning can help identify problems, such as wear and tear, corrosion, damage or thin pads at an early stage.
How long does it take to burnish brakes?
It takes around six times or 200 stops to burnish brake rotors and pads.
These were all the details about brake burnishing and cleaning, which are essential processes. When you buy a used car in the UAE, make sure you clean the brakes and use the burnishing process when changing rotors and pads. Since brakes are subject to failure, learn these tips to deal with car brake failure. Always ensure maintenance to avoid car brake failure.
