-
Decontamination: Fine grit is effective for removing surface contaminants, such as oils or dirt, that can accumulate on the pads. A clean and smooth surface improves friction and brake responsiveness.
-
Bedding-In Process: When you’re bedding in new brake pads, using fine grit helps in achieving the desired surface texture that can better integrate with the rotor, enhancing the overall braking efficiency.
-
Adjustment of Pad Shape: If slight adjustments to the pad shape are needed, fine grit allows for precise alterations without oversanding, which could compromise the pads.
When selecting sandpaper for your bicycle brake pads, consider the type of brake system in use (disc vs. rim) and always test on a small area first to ensure the desired effect is achieved.
