🛠️ Expert Installation & Field Note

From our shop experience specializing in heavy-duty commercial hydraulic braking systems since 1985:

Power Steering System Fluid Flush: GMT900 hydroboost circuits operate under high power steering pump pressures. Always flush old power steering fluid completely before installation to prevent debris from binding internal spool valves or causing shaft seal leaks.
Pedal Position Switch Care: When connecting the brake pedal pushrod under the dash on Silverado/Sierra models, exercise caution with the brake pedal position sensor and retaining clip to prevent electrical miscalibration.
Anti-Corrosion Finish: Our proprietary black protective coating shields raw cast iron against road salt, moisture, and extreme under-hood operating temperatures.
