Product Overview
This right upper disc brake pump is designed as a replacement hydraulic brake master cylinder and lever assembly for selected 50cc, 70cc, 90cc, 110cc, 125cc, 150cc, 200cc, and 250cc ATVs, go karts, 4-wheelers, quads, motorcycles, scooters, mopeds, and buggies.
It is made for 7/8" / 22mm handlebar installation and uses an M10 x 1.25mm banjo bolt connection. The brake pump helps transfer hydraulic pressure from the hand brake lever to the brake caliper, supporting disc brake operation when the brake hose, caliper, and mounting layout match.
A worn, leaking, loose, or damaged brake pump may cause soft lever feel, poor braking response, brake fluid leakage, or unsafe braking performance. This black aluminum alloy replacement is suitable for repairing compatible hydraulic disc brake systems.
Please compare the handlebar diameter, banjo bolt size, brake hose fitting, lever position, reservoir shape, and product photos with your original brake pump before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This right upper disc brake pump may fit selected 50cc, 70cc, 90cc, 110cc, 125cc, 150cc, 200cc, and 250cc ATVs, go karts, scooters, mopeds, motorcycles, quads, and buggies. Fitment depends on the handlebar diameter, banjo bolt size, brake hose fitting, lever position, and hydraulic brake layout rather than model year alone.
Do I need to match the OEM part number?
Matching the OEM part number is helpful, but for this brake pump, the most important details are the 22mm / 7/8" handlebar fitment, M10 x 1.25mm banjo bolt size, brake hose fitting, and right-side mounting layout.
What models or situations does this part not fit?
This brake pump may not fit vehicles with a different handlebar diameter, different banjo bolt thread, different brake hose connection, left-side brake pump layout, cable-operated brake system, drum brake system, or model-specific hydraulic master cylinder assembly.
What should I check before ordering?
Before ordering, check your original brake pump position, handlebar diameter, banjo bolt size, brake hose fitting, reservoir shape, lever style, brake line routing, and product photos. Make sure your original setup matches the listed right upper position, 22mm handlebar mount, and M10 x 1.25mm banjo connection.
