1115 Large Rectangular Universal Brake Bleeder Adapter

The Motive Products 1115 Large Rectangular Universal Adapter is an all-metal adapter built for oversized rectangular master-cylinder caps found on classic American trucks, large-body SUVs, and full-size cars where the standard 1105 adapter is too small. Pair it with any Motive Power Bleeder tank for one-person brake bleeding on the largest domestic reservoirs.

Vehicle Fitment

Designed for vehicles with larger rectangular master-cylinder reservoir caps, including:

• Classic and vintage American trucks – full-size Ford, Chevy, Dodge pickups with oversized rectangular reservoirs
• Large-body American SUVs and wagons – Suburban, Bronco, Blazer, and similar with matching cap geometry
• Classic American cars where the standard rectangular adapter does not provide a proper seal
• Other domestic vehicles with a large rectangular single-chamber reservoir

If the 1105 adapter seals on your vehicle, this larger 1115 is not needed. Verify dimensions before ordering.

Key Features

• Larger Rectangular Profile – metal construction seals on oversized domestic reservoir caps where smaller adapters won't reach.
• All-Metal Build – corrosion-resistant; handles DOT 3 and DOT 4 brake fluid plus extended shop use.
• Quick-Disconnect Compatible – snaps onto any Motive Power Bleeder tank via stainless quick-disconnect.
• One-Person Brake Bleeding – pressurize to 15–20 psi and bleed all corners without a helper.

How to Use

Seat the 1115 adapter on the large rectangular reservoir cap, connect your Motive Power Bleeder, pump to pressure, and open each bleeder in sequence. Ideal for big-block restoration projects, work trucks, and fleet brake service. Pair with any Motive Power Bleeder tank for a complete one-person system.
