A-Premium Rear Centre Brake Hydraulic Hose for GM classics — pre-fitted OE-style replacement, correct fittings

A-Premium Rear Center Brake Hydraulic Hose is a direct-replacement brake line built to restore reliable hydraulic flow for the rear-center circuit on a wide range of classic GM cars, wagons, and trucks.

This hydraulic hose is engineered as an OE-style replacement for older General Motors vehicles where the original rubber lines have aged, cracked, or begun to leak. It’s manufactured to the dimensions, fittings, and mounting orientation required for rear-center brake applications across many Chevrolet, GMC, Buick, Oldsmobile, Pontiac, and Cadillac models from the 1970s through the early 1990s. The hose arrives pre-fitted with the correct connectors so you can replace a failed section without modifying hard lines or adapters.

Which models and years will this rear-center hose fit?

This hose covers an extensive list of GM platforms and body styles. It includes specific fitments for sedans, wagons, pickups, SUVs, and vans across Chevrolet, GMC, Buick, Oldsmobile, Pontiac, and Cadillac from mid-1970s to early 1990s. Fitment depends on brake type (drum or disc) and the vehicle’s original routing; always compare part numbers and geometry before installation.

• Cadillac Seville: 1976–1979 rear-center routing
• Chevrolet Bel Air, Vega, Monza and Camaro/Nova model coverage for mid-1970s
• Extensive Chevy/GMC truck and suburban coverage from 1974–1991 (varies by axle/brake size)
• Buick, Oldsmobile and Pontiac mid-1970s platform compatibility

How does this hose match the original brake plumbing?

The assembly is made to replicate factory hose lengths, end fittings and bracket locations so it installs in the same orientation as the OEM part. That reduces the need for custom bending or swapping adapters while maintaining correct brake line routing under the vehicle. If your original reference number matches one of the listed IDs, the hose is intended as a direct replacement.

• Pre-crimped connectors sized to factory thread and flare standards
• Length and mounting points designed to match OEM routing
• Made for rear-center circuit where a single flexible section connects hard lines to the axle

What reference numbers and part IDs correspond to this A-Premium hose?

This hose is cross-referenced to several common aftermarket and OEM numbers, which helps you verify fitment quickly. Use these reference IDs when comparing to a parts catalog, seller listing, or an OEM invoice to ensure a match. They cover many legacy part numbers used by suppliers and salvage sources.

• Reference numbers include: 18J2119, 2201018, H80967
• Also cross-referenced to: BH36765, 1244627, 17981073
• Additional IDs listed: 22112622, 9757657, 19173040

What should I check before installing this hose?

Confirm vehicle year, axle/brake configuration, and that the failed section is the rear-center flexible hose rather than a hard line or junction. Inspect mounting brackets and nearby lines for corrosion that could interfere with the new hose’s routing. Use new washers and torque specifications for hydraulic fittings to ensure a leak-free connection after installation.

• Verify vehicle model and brake type (drum or disc) against fitment lists
• Compare the old hose’s connector types and overall length to the replacement
• Bleed the brake system according to manufacturer procedure after fitting

Who is this for: This A-Premium rear-center brake hydraulic hose is aimed at classic GM owners, restoration shops, and DIY mechanics repairing aged brake plumbing on 1970s–1990s Chevrolet, GMC, Buick, Oldsmobile, Pontiac, and Cadillac vehicles. It’s suitable when you need a like-for-like flexible section that restores hydraulic integrity and preserves original brake line routing without custom fabrication.
