The brake booster is a device found in vehicles with hydraulic brakes. It amplifies the force applied to the brake pedal, making it easier to stop the vehicle.
The booster is located between the master cylinder and the brake pedal, and it uses the engine vacuum to create extra pressure.
So how to know if your brake booster has gone bad? Let’s find out…

What Does A Brake Booster Do?
When you depress the brake pedal, a plunger pushes against a diaphragm inside the booster. This action creates a vacuum, which sucks fluid from the master cylinder into the booster. The fluid then flows through a check valve into a chamber below the diaphragm.
As the chamber fills, it pushes against a piston connected to the brake pedal. This intensifies the pressure on the brakes, making it easier to stop the vehicle.
Without a brake booster, drivers would have to apply much more force to the pedal to stop the car.
