4L Manual Brake Bleeder Kit with 45mm Adapter
This manual pressure brake bleeder kit is designed for brake-fluid bleeding when used with a compatible master-cylinder reservoir. It combines a 4L fluid reservoir, a manual hand pump, a 45mm adapter, and a 1L reservoir bottle to support controlled brake-fluid service.
Key Features
- 4L fluid reservoir for fresh brake fluid
- Manual hand-pump pressure operation
- 45mm reservoir adapter
- 1L reservoir bottle for fluid collection
- Designed for one-person brake-fluid bleeding when correctly connected

How It Works
Fill the 4L reservoir with the brake fluid specified for the vehicle, attach the 45mm adapter only to a compatible reservoir opening, and build pressure with the hand pump. Follow the vehicle manufacturer's brake-bleeding procedure and bleed sequence at the wheels.

Compatibility: Check the Reservoir Before Ordering
The included adapter is 45mm. It may fit a compatible 45mm threaded brake-fluid reservoir opening, but vehicle make alone is not a fit guarantee. Reservoir designs can vary by model year, trim, market, and master-cylinder design. Measure the opening and confirm the thread style before ordering; do not force the adapter onto the reservoir.

Use Notes
Before adding pressure, make sure the adapter sits squarely and seals securely. Keep the brake-fluid reservoir from running dry during service, use only the brake fluid specified by the vehicle manufacturer, and release pressure before removing the adapter. Brake systems are safety-critical; follow the vehicle service manual or consult a qualified technician if you are unsure of the procedure.

FAQ
Will the included 45mm adapter fit my vehicle's brake-fluid reservoir?
It may fit a compatible 45mm threaded reservoir opening. Measure the opening and confirm the thread style before ordering, because vehicle make alone is not a fit guarantee.
Can one person use this 4L manual brake bleeder?
Yes. The kit is designed for one-person manual pressure bleeding when the adapter seals correctly and the vehicle manufacturer's procedure is followed. Keep the brake-fluid reservoir from running dry and use the vehicle-specified brake fluid.
What should I check if the system will not hold pressure?
Stop and check that the 45mm adapter is seated squarely on a compatible threaded reservoir opening. Inspect the adapter, hose connections, and seals for damage or contamination; do not force an adapter that does not thread on smoothly.
