Electric Brake Booster (Electromechanical Booster)
An electric brake booster uses an electric motor instead of engine vacuum to assist the driver's braking effort.
What is Electric Brake Booster (Electromechanical Booster)?
It suits hybrids and electric cars, which have no reliable engine vacuum. It can build brake pressure very quickly for automatic emergency braking. It supports smooth blending of regenerative and friction braking. Because it does not depend on vacuum, it works the same whether the engine is running or not.
How it works
Sensors measure pedal movement and an electric motor drives the master cylinder through a gear.
Why it matters for your car
Faults usually trigger warning messages and need diagnosis with a scan tool. Follow the manufacturer's procedure for bleeding and replacement.
