Replace Contaminated or Worn Brake Pads

Follow these steps to restore braking power by replacing contaminated or excessively worn pads:

1. Remove the wheel from the bicycle to access the brake caliper.
2. Remove the brake pads from the caliper according to your specific brake model's manual (typically by removing a retaining bolt or clip).
3. Inspect the caliper housing for any residual oil or debris and clean the area with isopropyl alcohol and a lint-free rag.
4. Ensure the new brake pads are the correct type for your caliper.
5. Install the new pads into the caliper, ensuring the spring clip is properly seated and the retaining bolt or pin is secure.
6. Reinstall the wheel, ensuring the rotor is centered between the new pads.
7. Perform the bed-in process: Find a safe, flat area, accelerate to a moderate speed, and firmly apply the brakes (without locking the wheels) to slow to a walking pace. Repeat this 10–20 times to transfer a fresh layer of pad material onto the rotor.

Safety Precaution: Avoid touching the rotor braking surface with your bare hands during this process, as skin oils will re-contaminate the new pads. Verify the fix by performing a test ride in a controlled environment to ensure consistent stopping force.
