Good To Know

Q: Do I need to bleed the brakes after installing this rear master cylinder? A: Yes, air must be purged from the rear brake circuit after installation to get a firm pedal and reliable stopping force.

Q: Can I reuse my existing brake line and reservoir? A: In most cases the original rear brake line and reservoir fittings work with this pump, but always inspect them for cracks or leaks before reuse.

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