Steps
Check your brake caliper and old pads to identify the correct replacement shape and size. Match the pad number to your scooter or bike model before ordering.
Choose the pad compound. Resin pads are quiet and gentle, sintered pads last longer in wet or heavy use, and ceramic pads balance both.
Remove the wheel or caliper as needed and take out the old pads. Push the pistons back into the caliper with a clean flat tool.
Clean the caliper and rotor with isopropyl alcohol. Fit the new pads and spring, then refit the caliper and wheel.
Center the caliper so the rotor sits evenly between the pads. Spin the wheel and check for rubbing before you tighten the bolts.
Attach the bleed syringe to the caliper nipple and the other to the lever reservoir. Open the nipple and push fresh fluid through until no bubbles come out.
Close the caliper nipple, then work the lever a few times to build pressure. Top up the reservoir and refit the cap.
Squeeze the lever hard and check every fitting for leaks. Wipe off any spilled fluid right away.
Bed in the new pads with a few gentle stops at low speed. Then test the brake firmly before riding normally.
Tips and common mistakes
Never let the lever reservoir run dry during bleeding or air will get back into the line.
Use only the fluid your brake maker specifies, since mixing mineral oil and DOT fluid damages seals.
Keep brake fluid off paint and plastic, and wear gloves because DOT fluid irritates skin.
If the lever still feels spongy after bleeding, repeat the process until no bubbles appear.
Questions
How do I know which brake pads fit my scooter?
Compare the old pad shape and number with the listing for your exact model. Take a photo of the old pad and match the outline and thickness.
Do I always need to bleed the brakes after changing pads?
No. If the lever still feels firm after you push the pistons back, a bleed is not needed. Bleed when the lever feels soft or you opened the system.
Can I mix pad types on one brake?
No. Fit the same compound on both sides of the caliper so the rotor wears evenly and braking stays balanced.
