130 Drum Brake Backing Plate with Hook

The DRUM PLATE [BSP130 WITH HOOK] is a high-strength brake backplate assembly engineered for electric scooters, commercial e-rickshaws, and light electric vehicles (LEVs) using 130mm drum brake systems. Designed to house the internal brake shoes, actuation cam, and return springs, this plate forms the structural foundation of the mechanical drum brake assembly on front or rear axles.

Constructed from heavy-duty die-cast metal alloy with an integrated torque retention hook, this backplate mounts directly to the wheel axle and chassis fork. The integrated anchoring hook engages the vehicle frame to absorb rotational braking torque, preventing plate spinning during hard deceleration. Compatible with standard 12V to 60V DC electric vehicle platforms, it provides low flex, precise brake shoe alignment, and smooth lever response.

Key Features

• Integrated Frame Torque Hook: Heavy-duty cast hook locks firmly into the vehicle swingarm or front fork tab to absorb rotational torque during heavy braking.
• 130mm Brake System Profile: Precision-machined to accommodate standard 130mm brake shoes, actuation cams, and return springs.
• High-Strength Alloy Construction: Reinforced die-cast metal body resists flex, cracking, and mechanical distortion under high clamping force.
• Corrosion-Resistant Finish: Protective surface coating prevents rust and oxidation caused by rain, mud, and road wash.
• Pre-Bored Axle & Cable Ports: Standardized axle hole and cable guide mountings allow straightforward alignment during wheel hub reassembly.

Suitable Vehicle Types & Applications

• Electric Scooters & E-Bikes: Primary front or rear brake backplate replacement for Hero Optima, Okinawa, Pure EV, and similar 130mm drum e-scooters.
• Commercial E-Rickshaws & Fleets: Heavy-duty wheel brake plate for commercial delivery vehicles requiring high structural torque resistance.
• Custom Light EVs & Utility Vehicles: Standardized 130mm drum brake mounting hub for custom chassis builds.

System & Electrical Compatibility

• Universal 130mm Drum Hubs: Fully compatible with standard 130mm drum brake shoes and hub assemblies.
• Wide EV Sub-Circuits: Operates independently of electrical system voltage across 12V to 60V DC vehicle platforms.

1. Isolate Power & Remove Wheel Assembly:

Turn off the key ignition, trip the main DC circuit breaker, and elevate the vehicle. Disconnect the brake cable from the lever arm, unscrew the axle nut, and pull the axle bolt out to free the wheel assembly.

Verification: Wheel rotates completely free and zero live power is present before proceeding.

2. Remove Worn Backplate & Transfer Components:

Slide the old drum plate off the wheel hub. Unhook the brake shoes, return springs, and actuation arm, and transfer them onto the new DRUM PLATE [BSP130 WITH HOOK] (or install new 130mm brake shoes).

Verification: The actuation cam and brake shoes sit flat against the new plate and pivot freely.

3. Align Torque Hook & Mount Backplate to Axle:

Position the new drum plate over the wheel hub, ensuring the integrated torque hook engages firmly into the designated slot on the vehicle frame fork or swingarm. Reinsert the axle bolt.

Verification: The torque hook is fully slotted into the chassis frame tab with zero rotational movement.

4. Secure Axle & Adjust Cable Tension:

Tighten the main axle nut to manufacturer torque specifications, reconnect the brake cable to the actuation arm, and adjust tension barrel nuts.

Verification: Squeezing the brake lever engages the 130mm shoes firmly against the hub with zero backplate flex or twisting.

Power Isolation: Always turn off the ignition, trip the main DC circuit breaker, and secure the vehicle before servicing wheel hubs or brake plates.

Torque Hook Inspection: Regularly check the retention hook and frame mounting slot for physical wear, cracks, or play caused by sudden braking forces.

Pivot Lubrication: Apply a light dab of high-temperature grease to the internal actuation cam pivot pin, ensuring grease does not touch the friction lining.
