CRITICAL: Verify Specifications

Please confirm your firewall mounting pattern, 2.16-inch housing diameter, and stud thread dimensions (10 x 1.25mm) prior to installation. GMT800 platform full-size SUVs and trucks rely on precise hydraulic assist pressure to maintain confident braking under heavy towing, hauling, and daily driving demands.

“Engineered to restore immediate, high-pressure hydraulic stopping performance and firm pedal feel for GMT800 full-size SUVs and trucks.”

Restore maximum stopping confidence and eliminate spongy brake pedal feel with the Bexar Pro Hydroboost. Designed specifically for GM full-size trucks and SUVs—including 2003-2006 Cadillac Escalade (ESV/EXT), Chevrolet Tahoe, Suburban (1500/2500), Avalanche 1500, and GMC Yukon / Yukon XL (1500/2500)—this heavy-duty hydraulic power brake booster leverages power steering fluid pressure to deliver consistent, high-output braking assist. Reverse-engineered to correct original factory failure points, every unit is built with 100% new O.E. quality seals, diaphragms, and precision-tested check valves.

🛠️ Expert Installation & Field Note

From our shop experience specializing in truck and SUV hydraulic braking systems since 1985:

Power Steering System Fluid Flush: GMT800 hydroboost systems share fluid with the power steering pump and gear. Always flush old steering fluid completely before installation to prevent debris from clogging internal spool valves.
Pedal Linkage Alignment: Inspect the pedal pushrod attachment at the firewall bracket during reassembly to ensure straight actuation without binding, which prevents premature seal wear.
Corrosion Barrier: Our exclusive rust-prohibitive finishing process coats raw cast iron surfaces to withstand harsh road conditions, underbody splash, and long-term exposure.
