1122 Large Classic Car & Boat Trailer Brake Bleeder Adapter – 1-5/8" ID
The Motive Products 1122 Adapter is machined from corrosion-resistant aluminum to seal on the large 1-5/8" master-cylinder reservoir caps found on pre-1965 American cars and a wide range of hydraulic boat-trailer brake systems. One adapter covers two very different but equally underserved markets — vintage American restoration shops and the marine/trailer world.
Vehicle Fitment
- Pre-1965 American Cars – 1930s through 1960s Ford, Chevrolet, Chrysler, Buick, Oldsmobile, Pontiac, Cadillac, Dodge, Plymouth with large-bore single-reservoir master cylinders
- Hydraulic Boat Trailers – surge-brake disc and drum systems with 1-5/8" master-cylinder reservoir caps (EzLoader, Load Rite, Continental, and compatible brands)
- Classic marine inboard craft with matching hydraulic reservoir caps
Key Features
- 1-5/8" ID Seal – precision-machined for the large reservoir opening on pre-65 domestics and most boat-trailer brake systems.
- Corrosion-Resistant Aluminum – handles salt-air marine environments plus decades of brake-fluid exposure.
- Quick-Disconnect Compatible – snaps onto any Motive Power Bleeder tank via stainless quick-disconnect.
- One-Person Bleeding – pressurize to 15–20 psi and bleed drums or calipers without a helper or compressor.
How to Use
Seat the 1122 adapter onto the large reservoir cap, connect your Motive Power Bleeder tank, and pump to 15–20 psi. Bleed each corner in sequence. Essential for pre-show prep on classic American iron and pre-season boat-trailer commissioning. Pair with any Motive Power Bleeder tank for a complete one-person system.
