Frequently Asked Questions

Q: What brake disc sizes is the BF02 Small Crab caliper compatible with?

A: The BF02 dual piston disc brake caliper is designed for use with 200–220 mm brake discs. It is compatible with most 10–12 inch wheels commonly found on electric motorcycles, electric scooters, and electric bicycles.

Q: Do I need special tools or machining to install this brake caliper?

A: No special tools or grinding are required. The caliper uses standard mounting holes and a universal oil pipe interface, allowing straightforward installation even for beginners. Installation instructions are included in the package.

Q: Is the caliper suitable for both front and rear wheel installation?

A: Yes. The BF02 caliper features standard installation holes that support both front and rear wheel fitment, making it a versatile upgrade for your full braking system on electric motorcycles and e-scooters.

Q: How does the dual piston design improve braking performance?

A: The dual piston structure distributes clamping force evenly across the brake pad surface, producing linear and progressive force output. This means you get clear tactile feedback at light squeeze, firm and stable stopping under hard braking, and consistent performance even in wet or slippery conditions — a notable improvement over single-piston or stock factory setups.

Q: Is the caliper waterproof and resistant to dirt?

A: Yes. The BF02 caliper incorporates high-spec sealing components and a dust-proof structure that make it resistant to water and mud. It can withstand high-pressure washing during rainy rides and routine car washes without compromising the seal or braking function.
