Disk brake maintenance

Videos

Poor brake maintenance not only reduces the longevity and performance of your vehicle but also contributes to accidents and injuries, as well as road deaths due to collision. The braking system of your vehicle is complex but surprisingly simple to maintain yourself. It is important you inspect and make necessary repairs to every component to ensure all parts are in working order. These parts include the master cylinder and brake line, brake pads, callipers, and rotors. Your car should come with a recommended brake maintenance schedule in the manual; however, a good rule of thumb is to check your brake pads every 15 000 km and replace your fluid every 30 000 km. These estimates depend on your vehicle and driving style. A good auto parts store will be able to bet determine the right brakes for your vehicle and perform any other more complex maintenance and repairs needed.

Know the Warning Signs

Know the Warning Signs.  Even if you’re not a mechanic, you can still learn to recognize the signs your brakes might have an issue. Knowing what to look, listen, and feel for could make the difference between catching a problem before it gets worse and having a potentially serious collision.

You might hear squeaks or grinding when you brake or feel vibrations through your suspension or steering wheel when you push the brake pedal. Your pedal might feel mushy all of a sudden or fall closer to the floor when you push it. You might smell an unfamiliar burning or noxious odour as you’re driving or after you park. A brake system warning light could appear on your dash.

The following should be done when servicing disk brakes:

Check Brake Pads and Rotors

The brake pads and rotors are the point of contact between your braking system and your tires. These elements deteriorate more easily than other components and require more frequent maintenance. Friction between the tires and the brake pads cause heat, and this heat wears down the brake pad. It is important to inspect the quality and depth of the pads to make sure there is sufficient resistance. If you notice you need to depress your brake pedal further or smell a burning odour, or the distance it takes to stop increases drastically, it may be time to check and replace your brake pads and rotors. To check your brake pads and rotors at home, you need only remove the tire to assess the wear. If you notice wear or damage, replace them immediately, or take them to an auto shop for a disc brake repair service.

Flush Your Brake Fluid

When you depress your brake pedal, pressure builds and is transferred through the brake fluid from the master cylinder, through the brake lines, and into the callipers, which transfer this pressure to the brake pads and rotors. Brake fluid is, therefore, extremely important because it is the messenger between you and your car’s braking system. Unfortunately, brake fluid attracts moisture, which can be highly damaging to your braking system. Moisture in the brake fluid causes corrosion of the metal components of the brakes and reduces the boiling point of the fluid and affects the effectiveness of the brakes. Brake fluid should be checked and changed every 30 000 km. A cloudy or milky quality indicates the fluid must be changed.

Bleed the Brake Lines

In addition to flushing the brake lines to change the brake fluid, it is also a good idea to bleed the brake line to remove excess air. When small amounts of air become trapped inside the brake line, it can reduce the efficacy of the braking system. Bleeding the system removes the air from the brake line by depressing the brake pedal while adjusting the bleeder valve, and this should be done every 2– 3 years. This can be completed during a scheduled brake inspection service.

Replace or Upgrade Brake Parts

Sometimes it may be necessary to replace some elements in your braking system, and this can be a good opportunity to upgrade to higher performance or specialized components. Parts such as slotted disc brakes which are more heat resistant or switching to ceramic pads, which are quieter and produce less brake dust, are popular upgrades. Upgrading and replacing brake parts when necessary will improve the longevity and performance of your vehicle’s braking system

Braking System Care

One of the most effective ways to ensure the performance of your brakes is to look after them. There are many external factors that contribute to brake deterioration, such as:

Carrying too much weight Unnecessary, late, or heavy braking Wet weather

Avoiding these, and other situations that can affect your braking performance where possible, will keep your brakes performing better for longer and reduce the likelihood of brake failure related incidents.
