MV6840

Operation: Manual-pump pressure dispenser

Research-based review

QUICK VERDICT

A pressure brake-bleeding kit for compatible hydraulic systems and reservoir adapters. The vehicle procedure, fluid specification and correct adapter are essential parts of the buying decision.

Our take

The MV6840 is a substantive workshop purchase when compatible pressure bleeding is a recurring task. Its 5 L reservoir and seven-adapter kit support a different process from manually topping up a reservoir between pedal strokes. Check the vehicle pressure limit and adapter seal before buying; capacity and adapter count do not establish universal compatibility.

Best for

Compatible hydraulic brake or clutch systems whose manufacturer procedure permits pressure bleeding with a verified reservoir adapter.

Skip it if

The required adapter is absent, the system demands a different procedure or you expect the bleeder to replace an ABS scan-tool routine.

Pros

Manual-pump pressure dispenser
1.2 US gallon / 5 L capacity
Seven master-cylinder adapters in MVA6850 kit

Cons

Adapter coverage must be checked vehicle by vehicle
Vehicle pressure and fluid requirements still govern use
Does not perform an electronic ABS bleed command

What the reservoir and pump contribute

The MV6840 is a manual-pump pressure dispenser with a 1.2 US gallon / 5 L capacity, gauge and manual relief valve. Its purpose is maintaining a compatible pressurised fluid supply during the specified bleeding process. A large container does not mean all of its contents should be introduced into a vehicle; the service procedure determines the amount and sequence.

The adapter is a primary compatibility question

The documented package includes the seven-adapter MVA6850 kit. Check the actual reservoir neck and application information rather than assuming seven adapters cover every car. A poor seal can compromise the process and spill fluid. Before committing to the kit, identify the adapter required for the vehicles you service and whether the selected offer supplies it or needs another approved part.

Pressure and fluid are not adjustable guesses

Use the vehicle’s permitted pressure and exact fluid specification, together with the bleeder’s instructions and material compatibility limits. The gauge helps monitor pressure; it does not choose a safe value for the system. Keep clean fluid equipment separate from used-fluid containers and avoid cross-contamination. Follow the documented pressure-release procedure before disconnecting the equipment.

ABS routines and the rest of the kit

Some vehicles need a scan-tool-controlled bleed routine in addition to hydraulic bleeding equipment. The MV6840 cannot command valves or pumps, so a supported diagnostic tool may be necessary. Compare the 5610 and MK900-BT by exact function coverage if that is a regular need. The MV7201 extractor is for another fluid-handling method and should not be substituted simply because both products have reservoirs and hoses.

QUESTIONS & ANSWERS

Frequently asked questions

Does it include reservoir adapters?

The documented MV6840 package includes seven adapters in the MVA6850 kit. Check the exact package and vehicle fit.

Will it perform an ABS automated bleed?

No. Any required electronic routine needs a scan tool with confirmed vehicle-specific support.

What pressure should I use?

Use the vehicle and equipment instructions. This review does not supply a universal bleeding pressure.

Lisle 25750 — 25750 dual-piston brake caliper compressor. Compresses two push-back pistons together; Hand-operated squeeze mechanism. Not a universal rear-caliper wind-back or EPB tool. Follow the vehicle retraction and reservoir procedure.
Lisle 81850 — 81850 combination brake-lining thickness gauge set. Nine acetal gauges; Straight and offset access. Colour bands are screening aids; replacement decisions use vehicle limits and a proper inspection, not colour alone.
Lisle 28600 — Disc-brake piston wind-back tool. Rotates compatible rear-disc pistons into the caliper; Used with a 3/8-inch drive ratchet and extension. Match the engagement face and required rotation to the vehicle. An electronic parking brake may require a separate service mode; this tool does not provide that function.
