Will this rear brake master cylinder fit my 110cc dirt bike?

Yes, this master cylinder is designed to fit most 50cc to 125cc dirt bikes, including popular 110cc models. Just make sure your bike has a standard 45mm mounting distance and 10mm banjo bolt size to ensure compatibility.

Is it hard to install this brake master cylinder on my ATV?

Not at all! Many customers find installation straightforward thanks to the universal bolt-on design. It matches common mounting specs, and you should be able to install it using basic tools. Plus, bleeding the brake system afterward is easy with the included high-temp resistant seals.

How durable is the black anodized finish on this part?

The black anodized coating is rugged and corrosion-resistant, made to withstand rough trail conditions and exposure to dirt and moisture. It helps keep the aluminum body protected and looking good for long-term use even in off-road environments.

Will this master cylinder improve my rear brake performance?

Absolutely! It offers sensitive and linear brake feedback, meaning you get better control and more precise braking response compared to many stock units. The optimized hydraulic flow helps you modulate your brakes smoothly on varying terrains.

Do I need any special parts or tools to replace my current master cylinder with this one?

You typically won't need special tools—standard wrenches and screwdrivers will work for installation. The master cylinder is a direct bolt-on for most compatible bikes and comes with premium seals to ensure no leaks. Just follow your bike’s manual for brake bleeding after installation.
