Electric scooter brake pads: wear signs, pad types and when to replace them

Where the pads are on your scooter

Only some brakes use pads, so start by checking which you have. Our guide to electric scooter brakes explained covers how each type works. For pads, what matters is this:

• Disc brakes have a caliper that squeezes two pads onto a metal rotor on the wheel. The NANROBOT G3 uses dual mechanical discs, the KUKIRIN G2 has discs front and rear, and the Kaabo Mantis King GT uses full hydraulic brakes with 5.5 inch discs and EABS.
• Drum brakes hide curved shoes inside the wheel hub. The NAVEE GT3 Pro pairs a front drum with a rear EABS motor brake.
• Electronic and regenerative brakes use the motor and have no pads at all.
• Foot brakes press the fender onto the tire, so the tire takes the wear.

How to check pad wear

A monthly look takes a minute. Switch the scooter off first.

• Look into the caliper. Shine a flashlight into the slot on the caliper, from the top or the front. You will see the two pads, one on each side of the rotor, each a layer of friction material on a metal backing plate.
• Measure what is left. Replace the pads when about 1 mm of friction material remains, or at the minimum your manual gives. Some pads have a groove cut into the material. When the groove is gone, so is the pad.
• Check both pads. On many mechanical calipers only one pad moves, and it can wear faster than the other.
• Check the rotor. Deep grooves, a blue tint from heat, or a rotor that wobbles as the wheel turns all need attention. Rotors also have a minimum thickness, often stamped on the rotor itself.
• Feel the lever. If the lever pulls closer to the grip than it used to, the pads may be wearing, or a mechanical brake cable needs adjusting.

Signs your brake pads are worn

• Grinding or scraping. The backing plate may be touching the rotor. Stop riding and replace the pads before the rotor is ruined.
• Longer stopping distances, or brakes that fade on long descents.
• Lever travel that keeps growing, even after you adjust a mechanical brake.
• Squealing that cleaning does not cure. Glazed or contaminated pads squeal. Clean rotors fix some of it, worn or oily pads do not.
• Uneven braking, where the scooter pulls or one brake feels much weaker than the other.

Resin, semi-metallic and sintered pads

Disc brake pads come in a few compounds, and each trades grip, noise and life differently.

• Organic or resin pads are quiet, bite well from cold and are gentle on rotors. They wear faster and fade sooner under heavy heat, such as long descents with a heavy load.
• Semi-metallic pads mix metal fibers into the compound. They last longer and handle heat better, and they can be a little noisier.
• Sintered metallic pads are made from pressed metal particles. They last longest and cope best with heat, wet and grit, and they need a rotor rated for them.

Use the compound the maker fits or recommends for your brake. Pad shape matters even more: calipers from different brands take different pads, and a pad that almost fits will not hold.

What wears pads faster

• Speed and weight. More speed and more load mean more energy for the pads to turn into heat on every stop.
• Hills. Long descents with the brake held on wear pads fastest of all.
• Wet and gritty roads. Water carries grit into the caliper, and it grinds pads down quickly. Wipe the rotor clean after wet rides, as our guide to how to clean an electric scooter shows.
• Leaning on one brake. Use both brakes, so one set of pads is not doing all the work.
• Motor braking settings. On scooters with electronic braking, the motor takes some of the load on every stop. The AOTOS E3 lets you adjust the regenerative braking strength in its app.

Replacing disc brake pads

On many scooters, disc pads can be changed with basic tools. Follow your manual for your model, and leave it to a shop if anything looks different from what the manual shows.

• Switch the scooter off and support it so the wheel can turn freely.
• Remove the pad retaining pin, clip or bolt, and slide the old pads out of the caliper. Some calipers need the wheel removed first. If that means unplugging the motor cable, have a technician do it.
• On hydraulic brakes, gently push the pistons back into the caliper with a plastic tire lever to make room for the thicker new pads. Never squeeze the brake lever while the pads are out.
• Fit the new pads with their spring or clip, the friction side facing the rotor, and refit the retaining pin. Keep your fingers off the friction surface.
• On mechanical brakes, readjust the pad position and the cable so the pads clear the rotor and the lever feels firm.
• Spin the wheel to check for rubbing, squeeze the lever several times, and test the brake at walking pace before riding.

Replace both pads in a caliper at the same time. A hydraulic lever that stays spongy after new pads usually needs bleeding with the fluid the maker names, which is best left to a technician.

Bedding in new pads

New pads need bedding in before they reach full strength. Bedding in lays a thin, even layer of pad material on the rotor.

• Find a quiet, flat, dry place with plenty of room.
• Ride at a moderate speed and slow firmly to walking pace without locking the wheel. Repeat ten to twenty times.
• Do not come to a complete stop with the brake held hard while the rotor is hot.
• Let the brakes cool, then check the lever feel and the stopping distance.

Drum brake shoes

Drum brakes last a long time because the shoes are sealed inside the hub. When lever travel grows, adjust the cable as your manual shows. When the shoes finally wear out, the wheel has to come off and the hub opened, and on some models the drum is built into the motor wheel. That is a job for a shop.

Getting the right pads

Note the caliper brand and model, or send us your scooter model and a photo of the caliper, and we will help you find pads that match. Brake pads are wear parts, which warranties usually treat differently from the motor or battery. A pad or caliper that was faulty when it arrived is a different case, as our electric scooter warranty guide and our warranty page explain.

Check your pads as part of the monthly routine in our electric scooter maintenance checklist. If braking problems come with other faults, such as power cutting out, read our electric scooter troubleshooting guide.
