🛠️ Expert Installation & Field Note

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

Pushrod Alignment: Ensure your firewall pedal pushrod runs completely centered during installation. On Express and Savana van firewalls, tight engine cowl clearance can force pushrod binding, which quickly causes internal seal scoring and fluid leaks.
Hydraulic System Flush: Hydraulic boosters are highly sensitive to microscopic contamination. We mandate a complete power steering fluid flush before connecting this unit to protect the new internal spool valves and check valves.
Corrosion Barrier: Our exclusive rust-prohibitive finishing process seals the raw iron casing against moisture and road chemicals, preventing external degradation over extended service cycles.
