Joyor S10-S-Z · Brakes
Brakes squeal or squeak
A loud squeal usually means something dirty or glazed on the pads or disc. Clean first.
Is this your problem?
- High squeal when braking, worse in the wet
- Brakes noisy after cleaning or oiling the scooter
Likely causes
Look at the disc: shiny rainbow or oily marks are contamination. Wiggle the caliper.

Step by step
Tap a step when it’s done to keep your place.
- Tighten caliper and disc bolts
Snug, not huge force. A torque wrench is best if you have one.
- Clean the disc
Isopropyl alcohol on a clean cloth, both sides, until the cloth stays clean.
- Check the pads
Take the pads out. If they are oily, replace them: oil soaks in and cannot be cleaned out. If only glazed, you can lightly sand the surface flat on fine sandpaper on a table.
- Bed the pads in again
10–20 firm stops from gentle speed.
Stay safe
- Never spray lube anywhere near the brakes. Cover them when cleaning.
When to take it to a shop
If the noise stays after new pads and a clean disc.
