⚠ Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985:
- Pushrod Alignment: Confirm the booster’s pedal rod length and end-style matches your old unit exactly before mounting. Improper rod geometry is a leading cause of pedal travel issues.
- Seal Integrity: New Oval O-rings are provided. Always replace these when mounting your backup pump motor to ensure a high-pressure, leak-free seal.
- Bench Bleeding: For optimal performance, follow the official Hydromax bleeding procedures to ensure no air is trapped in the hydraulic galleries.
