Good To Know

Q: How do I know this rear foot brake master cylinder pump fits my machine? A: Check the mounting bolt spacing, pedal connection, and brake line fitting on your existing unit against this pump before ordering. Displacement alone does not guarantee fitment, since layouts vary between models.

Q: Does this pump come with brake fluid or a bleeder kit? A: No, brake fluid and bleeding tools are not included. The rear brake system will need to be filled and bled after installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
