Speedway Motors Rubber Front Brake Hose Set for 7/16-20 GM Calipers, 3/8-24

The Speedway Motors Rubber Front Brake Hose Set is a plumbing solution for vintage GM disc brake upgrades. Designed specifically for 1955-1974 GM platforms undergoing front disc conversions with 1969-1988 GM single-piston calipers, this set provides direct-fit plumbing to get your hydraulic lines connected without guesswork.

Built from durable rubber, these hoses maintain a traditional factory look while handling the necessary movement of your calipers during suspension travel and routine maintenance. Each hose features a 7/16-20 banjo fitting on the caliper end and a 3/8-24 inverted flare female connection tailored for standard 3/16-inch hard brake lines and tube nuts. Matching banjo bolts are included in the box to speed up your installation.

Mounting is straightforward thanks to hose ends fitted with clips designed to seat into OEM 1969-1988 GM frame tabs with a 5/8-inch hex profile. While the package includes the hoses, clips, and banjo bolts, you will need to supply your own new crush washers to complete the seal at the caliper. Builders working on custom chassis setups will also need to source frame tabs separately if their vehicle lacks original mounting points.

Verdict: This hose kit is a practical, direct-fit choice for builders completing a front disc brake swap on 1955-1974 GM cars using 1969-1988 single-piston calipers. Just make sure to have fresh crush washers ready before you begin bleeding the system.
