MOOSE UTILITY DIVISION 1731-0724 Front Master Cylinder Cap Kit - Honda

OVERVIEW

Restoring precise hydraulic pressure and consistent lever action begins at the front brake reservoir. This Moose Utility Division 1731-0724 front master cylinder cap kit replaces hardened plastic covers with fresh OEM-grade sealing components. Manufactured by Nissin in Japan, it delivers exact material standards and direct fitment for vintage and modern Honda four-wheelers.

ENGINEERING & PERFORMANCE

The cap assembly controls air ingress and fluid level exposure, making its structural integrity critical for reliable front end engagement. Built with resilient rubber diaphragms and impact-resistant polymer housings, the kit resists UV degradation and track debris without shrinking or warping. Factory-spec thickness and reinforced mounting bosses maintain proper bore alignment while preventing vacuum lock. The design follows direct replacement procedures so riders restore crisp pedal feel without modifying underlying brake lines or calipers.

WHY RIDERS CHOOSE THIS

Riders choose this cap kit to eliminate reservoir failures that cause spongy levers and unpredictable stopping distance. The Nissin-built housing and compliant diaphragm protect the master cylinder bore from trail debris and moisture, maintaining consistent hydraulic engagement over time. Factory-dimensioned mounting plates and included fasteners restore proper pedal height and bite point without aftermarket modifications. This exact configuration remains the preferred maintenance route for Honda ATVs where front-end consistency dictates trail confidence.
