4AN Brake Hose, Reservoir to Rear Master

This is the OEM brake hose that feeds brake fluid from the reservoir to the rear master cylinder on the Rush SR. It's a pre-made 4AN hose designed to fit the dual master cylinder brake system exactly as installed from the factory.

The Rush SR uses separate front and rear brake circuits, each with its own master cylinder. This hose handles the low-pressure feed side of the rear circuit — routing fluid from the reservoir down to the rear master cylinder before it's pressurized and sent to the rear calipers. Using the correct 4AN sizing on the feed line ensures adequate fluid supply to the master cylinder without restriction.

This is a direct OEM replacement. If you're rebuilding your brake system, replacing damaged lines, or doing a full fluid system refresh, this is the correct hose for the reservoir-to-rear-master connection.
