⚠ Expert Installation & Field Note

Based on our shop experience specializing in heavy-duty brakes since 1985:

  • Pushrod Alignment: Ensure perfect pushrod alignment to prevent side-loading internal seals. Misalignment is the leading cause of premature failure in Hydromax units.
  • Legacy Upgrades: This unit replaces older boosters (Casting #2771424 or #2771819). To adapt the modern connection to the older 1-pin style, you must use our Flow Switch Adapter.
  • Seal Maintenance: New Oval O-rings are included; ensure all surfaces are clean before securing the backup pump motor to maintain hydraulic integrity.

CRITICAL: Verify Specifications

Always verify that your current booster body is stamped with Casting # 2772114. Ensure the pedal rod length and shape match your original unit before attempting installation.

Core Return Program

Return your old core within 90 days for a $50 refund. We keep heavy-duty fleets running sustainably.
