1130 Boat Trailer Brake Bleeder Adapter – 3/4" Press-Fit Style

The Motive Products 1130 Boat Trailer Adapter uses a 3/4" press-fit design that seats directly into the boat-trailer master-cylinder reservoir — no clamps, no tools, no fuss. Snap it into the reservoir, connect your Motive Power Bleeder tank, pressurize, and bleed the trailer brake system solo at the marina or in the shop.

Vehicle Fitment

Designed for hydraulic boat trailers with a 3/4" press-fit master-cylinder reservoir opening:

• Hydraulic surge-brake boat trailers – EzLoader, Venture, Load Rite, Shoreland'r, Continental Trailers, and other brands using the 3/4" press-fit reservoir style
• Marine disc and drum brake trailer systems with matching reservoir geometry

If your trailer reservoir uses a threaded or cap-style opening, see the 1122 or 1135 adapters instead.

Key Features

• 3/4" Press-Fit Design – inserts directly into the reservoir without clamps or threads; clean, fast connection every time.
• Marine-Grade Construction – corrosion-resistant materials built for salt-air environments and DOT 3/4 fluid exposure.
• Quick-Disconnect Compatible – connects to any Motive Power Bleeder tank via stainless quick-disconnect.
• One-Person Trailer Brake Bleeding – pressurize to 15–20 psi and bleed each corner without a second person.

How to Use

Press the 1130 adapter into the 3/4" reservoir opening until seated, connect your Motive Power Bleeder hose, pump to 15–20 psi, and crack each caliper or wheel-cylinder bleeder in sequence. Ideal for pre-season trailer commissioning and post-storage brake system refreshes. Pair with any Motive Power Bleeder tank for a complete one-person marine system.
