0120 GM Bi-Level Brake Bleeder Kit – Rectangular Front & Rear Reservoir Adapters

The Motive Products 0120 GM Bi-Level Bleeder Kit is the complete solution for GM vehicles equipped with a rectangular bi-level master cylinder — the dual-reservoir design used on a wide span of classic and modern GM cars and trucks. The kit includes the Motive pressure tank, supply hose, and both the front and rear rectangular adapters, so you can service each chamber independently for a full, clean brake fluid change.

Vehicle Fitment

Designed for General Motors vehicles with a rectangular bi-level (dual-chamber) master cylinder, including:

• Classic GM – 1960s–1980s Chevrolet, Buick, Oldsmobile, Pontiac, Cadillac with split rectangular reservoirs
• Modern GM trucks and SUVs – Silverado, Sierra, Suburban, Tahoe, Yukon with bi-level master cylinders
• Camaro, Firebird, Corvette and other performance GM platforms with dual rectangular reservoirs

Confirm your master cylinder uses the rectangular bi-level (two-chamber) design before ordering — single-reservoir GM vehicles use a different adapter.

Kit Contents & Key Features

• Motive Pressure Tank – corrosion-proof reservoir with hand pump and gauge.
• Front and Rear Rectangular Adapters – each seals independently on the corresponding bi-level reservoir chamber.
• Chemical-Resistant Supply Hose – connects tank to each adapter in sequence.
• Complete One-Person System – pressurize each chamber in turn; no helper or air compressor required.
• Durable Construction – all components resist DOT 3/4 brake fluid and daily shop use.

How to Use

Start with the front reservoir: seat the front adapter, connect the Motive tank, pump to 15–20 psi, and bleed front calipers until clean fluid flows. Swap to the rear adapter and repeat for rear circuits. The bi-level design keeps front and rear hydraulics isolated, so service each chamber separately for complete fluid renewal.
