Replacing a disc brake grinding machine is not really a DIY-friendly task. However, it can be done provided the right tools are available. Below are the steps to take:
First, it is very important to read the manufacturer's service manual. This will give users all the detailed instructions needed for the specific vehicle service manual.
The first step is to remove the wheels to access the brakes easily. Next, the brake caliper is removed. To do this, the brake caliper mounting bolts should be loosened and the caliper should be lifted off the brake pads and onto the suspension component using a bungee cord or rope. If a vehicle comes with a brake caliper that is in one piece, it is advisable to loosen the bolts before jacking up the vehicle.
The next step is to remove the worn-out brake pads. This is done by removing the brake pads retaining clips and sliding the pads out of the rotor. Thereafter, the brake caliper should be pushed or pulled to make space for the new pads. This can be done using a brake caliper tool or brake pad insertion tool. The new brake pads should be fitted into the rotors and the brake caliper should be fitted back over the new pads.
The final step is to put back the wheels and lower the vehicle. Before doing this, make sure to pump the brake pedal several times to make sure the brake caliper piston makes contact with the pads. This also helps to push back the brake caliper. To ensure safety, it is advisable to always check that the brake fluid level is at the recommended height.
Q1: What causes a disc brake grinding sound?
A1: A disc brake grinding sound occurs when the brake pads wear down, and the metal backing plates make contact with the rotor. Another possible cause is debris trapped between the pad and rotor or within the caliper. The last potential cause is worn-out brake components, such as the pads, rotors, or caliper, which can lead to metal-on-metal contact.
Q2: Can people drive with brakes that grind?
A2: No, it is unsafe to drive a vehicle with grinding brakes. Brake grinding can compromise braking performance and pose a safety risk. Drivers should address brake grinding immediately to prevent further damage and ensure safety.
Q3: How long does it take to fix grinding brakes?
A3: The time required to fix grinding brakes depends on the issue's severity. Minor problems, like adjusting loose components or replacing worn brake pads, can be fixed in an hour or two. More complex issues, such as brake rotor replacement, may take four hours or more. Consult a mechanic for an accurate estimate.
Q4: Is it necessary to replace all brake pads at once?
A4: It is advisable to replace all brake pads on an axle simultaneously. This maintains even braking performance and prevents imbalance, which can cause handling issues and premature wear on new components.
Q5: What is the disc brake grinding machine?
A5: The disc brake grinding machine is a tool used to rectify or resurface brake discs or rotors. Over time and with regular use, these components can develop uneven wear, minor surface imperfections, or a condition known as "brake disc thickness variation" (BDTV). This last condition is characterized by variations in the thickness of the brake discs, which can lead to vibrations and reduced braking efficiency. When users grind the discs, they eliminate any irregularities, ensuring a perfectly smooth and even surface. By restoring the rotors' even surfaces, the grinding machine enhances brake performance and extends the lifespan of brake pads and other associated components.
