The brake pad and brake rotor are the two main components in a BMW’s braking system. They are the components which directly come into contact with the wheels to stop or slow down the vehicle. However, due to the buildup of friction between them and the wheels, they tend to wear out over the course of using the vehicle. Here, we will discuss signs which indicate a need for the replacement of the brake pads and rotors in a BMW vehicle.
Signs and Indicators for Brake and Rotor Replacement Signs
Brake pads and rotors have a specific width required for them to function in the braking system; once they wear out beyond this limit, certain problems and issues begin to arise. These problems are used as indicators to know when the pads and rotors need replacement. Listed below are some of the most common signs you may experience if your brake components are worn out.
Reduced Overall Braking Performance
Worn-out brake pads or rotors will make your BMW’s braking system feel less responsive than it usually is. The vehicle will take more time and cover longer distances when the brakes are applied to stop or slow it down. This is a major compromise to your road safety and should be addressed immediately to prevent accidents.
Vibrations and pulses in the brake pedal
A vehicle with a worn brake disk or rotor might experience pulsations or vibrations in the brake pedal whenever the brakes are applied. The vibrations arise from uneven wear in the brake disk, making some sides thicker than others. While this does not seriously affect your driving experience, it is important to promptly address it to prevent the damage from escalating.
Weird Sounds and Noises When Braking
A high-pitched screeching sound when applying the brakes indicates significantly worn-out brake pads. The noise comes from the direct contact of the metals in the wheels and brakes when the padding on them has been completely worn out. Some brake pads have wear indicators which are designed to produce these noises as an indication for a replacement.
Steps to Take When Noticing Brake Pad and Rotor Replacement Signs
When you notice any of these brake pad and rotor replacement signs, it is important to take action and carry out the following steps to ensure your safety.
- Confirm the signs: Drive your BMW and apply the brakes while trying to notice signs like a reduction in the braking performance, vibrations in the brake pedal, or screeching sounds.
- Inspect the brake pads: Measure the width of the brake pads using a brake pad thickness gauge or ruler to determine if they have the recommended minimum thickness of about a quarter of an inch, or 6 millimeters.
Contact a professional: Employ the help of an expert technician or visit a reliable auto repair shop. Here, further inspections are carried out to assess the problem and make plans for a proper replacement.
