When it comes to brake pads, sanding them can be necessary in some cases to remove glazing or contamination from the surface. Choosing the right grit sandpaper for the job is important to avoid damaging the brake pads and ensure a smooth and clean finish. In this article, we will discuss the appropriate grit sandpaper for brake pads and some tips for sanding them properly.
What grit sandpaper for brake pads?
The recommended grit sandpaper for brake pads is between 80 to 120. This grit range is considered coarse enough to remove any glazing or debris on the surface but not so abrasive that it damages the pad material. Using sandpaper with a higher grit, such as 220 or above, is not recommended for brake pads as it can leave the surface too smooth, reducing the friction between the pad and the rotor.
Tips for sanding brake pads
1. Remove the brake pads from the vehicle: Before sanding the brake pads, it is essential to remove them from the vehicle. It is also recommended to remove the brake rotor and caliper for better access to the pads.
2. Clean the brake pads: Wipe the brake pads with a clean cloth to remove any dust or debris on the surface. This will also help you identify any signs of glazing or uneven wear.
3. Use a sanding block: To ensure even sanding, use a sanding block rather than your hands. This will help you apply the same pressure across the surface, reducing the risk of uneven sanding.
4. Sand the brake pads: Hold the sandpaper against the brake pad and move it back and forth in a straight motion. Be careful not to sand in a circular motion as this can create grooves on the surface. Use light to moderate pressure while sanding, and avoid excessive pressure that can damage the pad.
5. Check the surface: After sanding, inspect the brake pad surface for any signs of glazing or uneven wear. If you notice any deep grooves or damage, replace the brake pad instead of sanding it.
6. Reinstall the brake pads: Once you are satisfied with the sanding, reinstall the brake pads and rotor. Make sure to follow the manufacturer's instructions for proper installation and torque specifications.
Sanding brake pads can help remove glazing or contamination on the surface, improving the braking performance. Using the appropriate grit sandpaper is crucial to avoid damaging the pad material and ensure a smooth finish. Remember to remove the brake pads from the vehicle, clean the surface, use a sanding block, and inspect the surface after sanding. By following these tips, you can sand your brake pads safely and effectively.
