Difficulty: EasyBrake Failure Management

If your vehicle's brake pedal suddenly sinks to the floor while driving, rapidly pumping the brake pedal may restore enough hydraulic pressure to slow down or stop the vehicle.

Answer: Answer

Answer

True. Rapidly pumping the brake pedal can rebuild hydraulic pressure needed to slow or stop the vehicle.
When total pedal resistance is lost, rapidly pumping the pedal can compress remaining fluid or air in the brake lines, generating enough temporary hydraulic pressure to slow down the vehicle.

Step-by-Step Solution

1
Recognize brake pedal failure.
The pedal sinks completely to the floor without slowing the vehicle.
Indicates a loss of hydraulic pressure or fluid in the primary braking system.
2
Pump the brake pedal rapidly several times.
Residual fluid is compressed, potentially building up partial pressure.
Pumping creates temporary hydraulic resistance to slow the car down safely.
