Brake discs

Brake discs ensure that a car slows down and comes to a stop in time. Pressing the brake pedal causes a piston in the master cylinder to move. This exerts pressure on the brake fluid in the brake lines. This pressure propagates to a wheel brake cylinder, where the pistons press the brake pads against the brake discs.

WHAT ARE BRAKE DISCS?

Brake discs, also known as brake pads, are metal discs attached to the wheel hubs of the car. During braking, the brake pads are pressed against the brake discs, creating friction and slowing down the vehicle. Brake discs are designed to withstand high temperatures and provide durability for effective braking performance. 

THE FUNCTION OF BRAKE DISCS

Brake discs' main function is to convert the kinetic energy of the rotating wheel into heat energy through friction. This friction is created when the brake pads are pressed against the brake discs. Properly functioning brake discs are vital for safe braking and optimum vehicle control.

WEAR OF BRAKE DISCS

Like brake pads, brake discs undergo wear due to the friction and heat generated during braking. The degree of wear can vary depending on various factors, such as driving style, road conditions and the quality of the brake discs themselves. It is important to regularly check the wear of your brake discs.

WHEN SHOULD BRAKE DISCS BE REPLACED?

Although the exact lifespan of brake discs can vary, here are some signs that it is time to replace your brake discs:

• Brake disc thickness: Regularly check the thickness of your brake discs. The car manufacturer usually specifies a minimum thickness that should not be exceeded. If your brake discs are thinner than the recommended minimum thickness, it is time to replace them.
• Wear indicators: Some brake discs have wear indicators, such as grooves or recesses. If these indicators are clearly visible, it is a sign that the brake discs need replacement.
• Vibrations or vibration: If you feel vibrations or vibration in the steering wheel or brake pedal while braking, this could indicate worn or warped brake discs. It is important to address this problem immediately and have the brake discs checked and replaced.
• Irregular wear: If you brand that the brake discs wear unevenly, for example if certain parts of the brake discs are more worn than others, this may indicate a problem with the brake system or the quality of the brake discs. Have this checked thoroughly and, if necessary, replace the brake discs.

TIPS FOR BRAKE DISC MAINTENANCE

Here are some tips to optimise the life and performance of your brake discs:

• Regular cleaning: Keep brake discs clean and free of dirt, rust and brake dust. Dirt build-up can hinder friction and reduce brake performance.
• Avoid overheating: Prevent excessive heat build-up by avoiding prolonged hard braking. Overheating can damage brake discs and adversely affect braking performance.
• Replace brake pads in time: Worn brake pads can damage brake discs. Make sure you replace brake pads on time to avoid unnecessary wear on the brake discs.
• Quality check: When replacing brake discs, choose high-quality parts from a reliable manufacturer. Quality brake discs offer better performance, durability and safety.
