1127 Wilwood 43mm Brake Bleeder Adapter

The Motive Products 1127 Wilwood 43mm Adapter threads directly into the 43mm Wilwood reservoir cap, giving you a leak-free, pressurized connection to any Motive Power Bleeder tank. Whether you're on a dedicated race car, a track-prepped street machine, or a custom performance build, the 1127 delivers one-person brake bleeding on the most popular Wilwood master-cylinder configurations.

Vehicle Fitment

Designed for performance vehicles and race cars equipped with Wilwood master cylinders and remote reservoirs using the 43mm ID cap, including:

• Wilwood Combination Master Cylinder and Remote Reservoir kits on performance street cars
• Dedicated road-race, oval, and drag cars with Wilwood pedal-box or remote-reservoir setups
• Custom brake system builds using Wilwood 43mm reservoirs in tube-frame and kit-car applications

For the larger 45mm Wilwood reservoir, use the 0127 adapter kit. Confirm your reservoir ID before ordering.

Key Features

• 43mm Thread Engagement – machined to mate precisely with Wilwood 43mm reservoir caps; holds 15–20 psi without leaking.
• Quick-Disconnect Compatible – snaps onto any Motive Power Bleeder tank via stainless quick-disconnect.
• All-Metal Construction – resists DOT 4 and DOT 5.1 racing brake fluid plus shop chemicals.
• One-Person Race-Day Bleeding – essential when servicing a car alone between sessions.

How to Use

Thread the 1127 adapter into the Wilwood 43mm reservoir cap, snap on your Motive Power Bleeder tank's quick-disconnect, and pump to 15–20 psi. Open each caliper bleeder until clean, bubble-free fluid flows. Swap fluid before every track day for consistent, fade-resistant brake performance.
