Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of routing hoses to avoid chassis chaffing and ensuring proper twist clearance during full-lock steering cycles. Always verify mounting bracket locations on heavy commercial frames to prevent line stress and potential failure. Proper line routing and secure mounting are vital for maintaining hydraulic integrity and safety under demanding fleet conditions.
Before ordering, physically inspect your existing brake line length, banjos, or flare fitting threads. Fleet and utility applications often have mid-year production changes and wheelbase variations that alter line routing. Confirm these details to ensure compatibility and proper fitment of the replacement caliper assembly.
