🛠️ Expert Installation & Field Note

From our shop experience specializing in heavy-duty commercial brakes since 1985:

Pushrod Alignment: Ensure your firewall pedal pushrod is perfectly centered during installation. On 1-ton Express and Savana van firewalls, tight doghouse clearances can cause subtle pushrod misalignment, leading to fast internal seal scoring and pressure loss.
Hydraulic System Flush: Hydroboost units are highly sensitive to microscopic metal particles and degraded fluid. We mandate a complete power steering system flush with fresh fluid before connecting this unit to protect the new internal spool valves.
Corrosion Barrier: Our exclusive rust-prohibitive finishing process seals the raw iron casing against road salt, condensation, and chemical spill exposure for maximum service life.
