🛠️ Expert Installation & Field Note
From our shop experience specializing in heavy-duty commercial brakes since 1985:
- Power Steering Fluid Hygiene: Heavy-duty commercial trucks run higher hydraulic line pressure. Old fluid contaminants or metal shavings will immediately ruin internal spool valves. Thoroughly flush your power steering pump and lines before installation.
- Centering Output Rods: Ensure proper alignment of the pedal pushrod on commercial C3500HD firewalls to prevent side-loading, which can destroy the front seal over heavy city route cycles.
- Corrosion Protection: Our specialized rust-inhibiting finish guards the cast-iron body against salt, moisture, and road chemical exposure for long service life.
