Joyor S10-S-Z · Brakes
Weak brakes or worn brake pads
The scooter takes longer to stop. Pads wear out; checking and swapping them is a normal job.
Is this your problem?
- Longer stopping distance
- Grinding or metal scraping sound when braking
- Lever pulls further than it used to
Likely causes
With a torch, look into the caliper from above and see how much pad is left on each side of the disc.

Step by step
Tap a step when it’s done to keep your place.
- Get the right pads
Pads must match your caliper’s shape. Order pads listed for the S10-S-Z, or take one old pad to a shop to match it.
- Remove the old pads
Pads are held by a pin or bolt through the caliper, often with a small clip. Remove the clip and pin, and slide the pads out. Some calipers need taking off the arm first (two bolts).
- Push the pistons back
New pads are thicker. Push both pistons back into the caliper, evenly, with a pad spreader or clean plastic tyre lever. Do not use a screwdriver: it scratches the pistons.
- Clean the disc
Wipe the disc on both sides with isopropyl alcohol on a clean cloth. Do not touch the braking surface with fingers.
- Fit the new pads
With the spring between them, same way round as the old ones. Pin and clip back in. Squeeze the lever several times until it feels firm.
- Bed them in
Ride at a gentle speed and brake firmly to walking pace, about 10–20 times. This lays pad material onto the disc and gives full power.
Stay safe
- Test on a quiet road before riding normally.
- Always change pads in pairs (both sides of a caliper).
When to take it to a shop
If the disc is scored deep, bent or thinner than the size stamped on it.
