Adjusting brakes on the Xiaomi electric scooter: a complete guide with photos and tips

Xiaomi scooters are some of the most popular vehicles in the city, but even they require regular maintenance. One of the key procedures is adjusting the brake system, which directly affects safety. If you notice that the braking distance has increased, there is a creak or the brake pedal has become too soft, it's time to adjust.

In this article, we will analyze all types of brakes installed on the Xiaomi model. M365, Pro 2, 1S, Essential and others, from classic mechanical disks to electronic (regenerative) ones, you'll learn how to diagnose a problem, what tools you'll need, and how to avoid adjustment errors. And if you've never repaired a machine, don't worry: Our step-by-step instructions with photos will help even a beginner to cope.

Important: improper adjustment can lead to complete failure of the brakes during the movement, so strictly follow the recommendations and do not neglect safety.

Types of braking systems on Xiaomi electric scooters: how they differ

Before you start adjusting, you need to understand what kind of braking system you have on your model, and that's what the tools, the algorithm, and even the frequency of service depend on.

Most Xiaomi scooters use three types of brakes:

• 🔧 Disk mechanical - the most common (installed on the M365, Pro, 1S). The brakes are done by pressing the pads against the metal disc on the wheel, requiring regular adjustment of the gap and replacement of the pads.
• 🛠️ Drums are less common (such as some Xiaomi Essential versions), pads are located inside the drum, which rotates with the wheel. Less efficient, but easier to maintain.
• ⚡ Electronic (regenerative) - uses the engine to brake and return energy to the battery. They do not have mechanical wear, but their effectiveness depends on the battery charge and speed.

Many models (e.g. Xiaomi Pro 2) are equipped with a combined system: disc brake on the rear wheel. + It's electronic on the front. It increases reliability, but it makes it harder to set up.

If you are not sure what type of brakes are installed on your scooter, look at the wheel:

• 🔍 Disc brake - a metal disc attached to the hub is visible.
• 🔍 Drum – the wheel is closed with a metal casing without visible mechanisms.
• 🔍 Electronic – no visible mechanical parts, braking occurs when releasing gas or pressing a lever.

Indications that brakes need adjustment

Don't wait for the brakes to fail completely. There are a few clear signs that it's time to adjust:

• 🚨 Increased braking distance - the scooter stops longer than usual.
• 🔊 Screaming or screeching when braking - indicates wear of the pads or getting dirt.
• 🛑 The brake lever has become too soft or, conversely, requires a lot of effort.
• 🌀 The wheel is blocked unevenly - the scooter takes away when braking.
• 🔥 Overheating of a disc or drum after heavy use.

If you notice any of these symptoms, don't delay adjustment, and it's especially dangerous to ignore the increased braking distance, which can lead to an accident.

⚠️ Attention: If the problem persists after adjustment, the brake pads or disc may be worn out, and if this is the case, replacement is required!

It is also worth checking the brakes after:

• 🌧️ Long driving in the rain (moisture can cause corrosion).
• 🚵 Falls or impacts of the scooter (possible displacement of mechanisms).
• 🔧 Wheel or bearing replacements.

💡

Before adjusting the brakes, always clean the machinery of dirt and dust. Use a soft brush and degreaser (for example, use a soft brush and a degreaser, WD-40), But avoid getting liquid on the pads!

Brake adjustment tools and materials

For self-adjustment of the brakes on the Xiaomi electric scooter, you will need:

• 🔧 Hexagonal keys (usually 4 mm and 5 mm) - for adjusting disc brakes.
• 🔨 Screwdriver cross - for drum brakes.
• 📏 A bar or ruler - to measure the gap between the pad and the disc.
• 🧴 Degreasing agent (e.g, WD-40 or isopropyl alcohol - for cleaning mechanisms.
• 🧽 Soft brush or cloth - to remove dirt.
• 🛡️ Protective gloves – to avoid getting your hands dirty and avoid cuts.

Some models (such as the Xiaomi Pro 2) may require a special key to center the brake disc, if not, you can use a flat screwdriver, but you need to act carefully so as not to damage the disc.

If you plan not only adjustment, but also replacement of pads, buy a set of brake pads for your model in advance. M365 And Pro fits pads with an articular MD-J063-001 (Original) or analogues from Yoosee, Ninebot.

⚠️ Warning: Never use oil or lubricant on brake pads and discs! this will lead to a loss of braking efficiency and can cause an accident.

4. Step-by-step: adjusting disc brakes on Xiaomi M365/Pro/1S

Disc brakes are the most common on Xiaomi electric scooters, and they include adjusting the gap between the pads and the disc, as well as centering the disc itself.

Turn the scooter upwards (fix on a table or chair)|Clean the brake mechanism of dirt with a brush and degreasing|Check the integrity of the pads (thickness must be at least 2 mm)|Prepare hexagonal keys (4 mm and 5 mm)-->

Step 1: Check and clean the mechanism

Turn the scooter over so that the rear wheel (where the disc brake is usually located) is at the top.

• 🔍 Brake disc – there should be no deep scratches or deformations.
• 🔍 Litches are a minimum thickness of 2 mm, otherwise replacement is required.
• 🔍 Brake cable - should not be rubbed or rusted.

Clean the disc and pads with a soft brush. If you have a lot of pollution, use a degreaser, but don't let it get to the rubber parts.

Step 2: Adjust the gap between the pads and the disc

The optimum clearance is 0.2-0.4 mm. For adjustment:

1. Find the adjustment bolt on the brake caliper (usually on top or side).
2. Use a hexagon by 4 mm to loosen the counternut.
3. Rotate the adjustment bolt clockwise to reduce the gap, or against to increase.
4. After setting up, fix the counternut.

Check the gap with a ruler or a rod. It should be the same on both sides of the disk.

Step 3: Centering the brake disc

If the disc is curved, the pads will wear out unevenly.

1. Relax the caliper mount bolts (usually two bolts by 5 mm).
2. Press the brake lever so that the pads press against the disc.
3. Holding the lever, tighten the calipers.
4. Release the lever and make sure that the disc does not touch the pads when the wheel is rotating.

If the disk is rubbing anyway, repeat the procedure or check it for curvature (in which case, replacement may be required).

💡

After adjustment, be sure to test the brakes at a safe speed (5-10 km / h) before a full ride!

5. Adjustment of drum brakes on Xiaomi Essential and other models

Drum brakes are less common, but their tuning is just as important, and the main goal is to ensure that the pads fit evenly to the inner surface of the drum.

Step 1: Dismantling the wheel and drum

To access the mechanism:

1. Remove the wheel by unscrewing the nuts or mount bolts.
2. Remove the drum by pulling it on yourself (you may need a light tapping with a rubber hammer).
3. Clean the inner surface of the drum and pads of dirt.

Step 2: Adjusting the tension of the pads

Inside the drum, you'll see two pads that are spread out by a spring.

1. Find the adjusting eccentric (usually at the top of the mechanism).
2. Turn it clockwise with a screwdriver so that the pads approach the drum.
3. Make sure the wheel rotates freely, but when pressed on the brake lever, it is blocked.

Step 3: Verification and Assembly

After adjustment:

• Put the drum back in place.
• Fix the wheel and check the brakes.
• If the brake is too tight or weak, repeat the eccentric setting.

⚠️ Warning: Drum brakes are more sensitive to overheating. After intense braking, allow the mechanism to cool down for 5-10 minutes to avoid deformation.

Adjustment of electronic (regenerative) brakes

Electronic brakes don't have mechanical parts, but their effectiveness depends on the settings in the firmware of the scooter. If braking is weak, try the following steps:

Step 1: Checking the battery level

Regenerative brakes work by converting kinetic energy into electrical energy, and if the battery is close to 100%, the system can automatically reduce the braking force so as not to damage the battery.

Step 2: Calibration of the brake in the mobile application

For models with Mi Home or Xiaomi Scooter support:

1. Connect the scooter to the application via Bluetooth.
2. Go to the Settings section → Brake system.
3. Select the Calibration of the electronic brake and follow the instructions on the screen.

Step 3: Reset the controller settings

If the brake is unstable (it is strong, then weak), a reset can help:

1. Turn off the scooter.
2. Press the power button for 10 seconds.
3. Turn on the scooter and check the brakes.

If the problem persists, the controller or speed sensor may be faulty, in which case contact the service.

7. Frequent errors in brake adjustment and how to avoid them

Even experienced scooters sometimes make mistakes that lead to breakdowns or inefficient braking.

• ❌ Too much tightening of the pads → It causes overheating and rapid wear.
• ❌ Using lubricant on pads or disk → The brakes become "slimy" and do not work.
• ❌ Ignoring the curved disk → uneven wear of pads and vibrations during braking.
• ❌ Adjustment by eye without measurement → The gap may be too large or small.
• ❌ Replacement of pads without cleaning the caliper → dirt accelerates the wear of new parts.

To avoid problems:

• ✅ Always use a barbell to measure the gap.
• ✅ After adjustment, check the brakes at the minimum speed (5 km / h).
• ✅ If the pads are worn by more than 50%, replace them instead of adjusting them.

If you're squeaking after you adjust the brakes, maybe the pads are of poor quality or the disc is deformed, and then replacing the components with the original ones will help.

8. when is the best time to contact the service

Not all brake problems can be solved by yourself.

• 🔧 Brake disc is deformed or has deep grooves.
• 🔥 After adjustment, the pad or disc is heated (the risk of fire!).
• ⚡ The electronic brake does not respond to settings in the application.
• 🛑 The braking distance exceeds 3-4 meters at a speed of 15 km / h (normal - 1.5-2 m).
• 🔊 There is a metal grinding - this may indicate complete wear of the shoe.

The cost of adjusting the brakes in the service is usually 500-1500 rubles, depending on the model and the complexity of the work. Replacing the shoes will cost 1000-2500 rubles (taking into account the cost of parts).

If you are not confident in your abilities, it is better to entrust the work to professionals - it is cheaper than repairing after an accident due to faulty brakes.

💡

Regular check of brakes (every 300-500 km) extends the service life of the pads and disc by 30-50%!
