Good To Know

Q: Does the rear brake system need bleeding after this pump is installed? A: Yes, air trapped in the line or caliper must be bled out after installation. Work the pedal and bleed at the caliper until it feels firm and consistent.

Q: Will this pump fit every LTZ400 model year? A: It is listed for the 2003 to 2008 range, but mounting and line details can vary. Check your machine's rear brake layout and serial number before ordering.

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