Brake Booster Electric Pump with Accumulator – Confident Stopping Power ️

Why you need it

This unit keeps constant hydraulic pressure for the brake booster and ABS. It gives strong pedal assist at low RPM, fast ABS response on gravel or wet roads, and stable braking when towing or off‑road.

How it works

An electric motor drives a precision pump that charges a pressure accumulator. A sensor and control circuit maintain target pressure, feeding the hydraulic booster and ABS modulator. Check and relief valves keep flow smooth and quiet. The accumulator stores energy so assist is instant, even with the engine idling.

What if it fails ⚠️

Long or hard pedal, pump running nonstop or not at all, ABS/VSC lights, warning buzzer, and longer stopping distance. In severe cases the pedal sinks and assist disappears. You may also hear harsh buzzing or see fluid leaks. Driving like this is unsafe.

Tech tips

Use correct brake fluid, prime the pump, and bleed with a scan tool to remove air. Inspect grommets and lines, clear fault codes, and verify pressure holds after key‑off.
