Xiaomi 4 Lite Gen2 drum brake is the mechanical assembly with a backing plate, brake shoes, return springs and an external operating arm. It fits into the wheel drum brake arrangement when worn or damaged mechanism components need replacing. This is an original replacement part.

Xiaomi 4 Lite Gen2 drum brake with backing plate

The shoes and springs are already fitted to a common base. An operating arm for the brake cable sits outside the plate, alongside the central axle opening. The set replaces this mechanism as one assembled component.

• Compatibility: Xiaomi 4 Lite 2nd Gen electric scooter.
• Type: drum brake mechanism.
• Base material: aluminium alloy.
• Round cover diameter: approximately 94 mm.
• Central opening diameter: approximately 11.7 mm.
• Package: 1 assembly with plate, shoes, springs and operating arm.

Wheel and brake contents

The shoe side shown in the photographs fits inside the wheel brake drum. The wheel, tyre, separate brake cable and handlebar lever are not included. Account for these separate components when planning a repair, particularly if the braking surface inside the wheel is damaged too.

Fitting and adjustment

Compare the central opening, plate shape and operating arm orientation with the original mechanism. During fitting, check the position of the shoes and springs, and keep friction surfaces free from oil or grease.

After connecting the cable, adjust its tension and check that the wheel rotates freely when the lever is released. Applying the lever should operate the brake progressively and the arm should return afterwards. Replacing this assembly alone may not resolve wear or damage in the wheel drum or brake cable.
