What should you do if you lose hydraulic brake pressure?
Loss of Hydraulic Pressure:
- Downshift – Putting the vehicle into a lower gear will help to slow the vehicle.
- Pump the brakes – Sometimes pumping the brake pedal will generate enough hydraulic pressure to stop the vehicle.
- Use the parking brake – The parking or emergency brake is separate from the hydraulic brake system.
What are the symptoms of a bad brake light switch?
The most common symptom of a faulty brake light switch is when brake lights don’t come on or stay on all the time. A faulty brake light switch can cause many problems. If a switch is bad, the brake lights won’t operate and the transmission shifter will not come out of “Park” position.
What does the auto park brake unit do?
This essentially locks the transmission in place and keeps the vehicle parked in place. The auto park brake unit contains an hydraulic pump and double-acting hydraulic cylinder.
How does the hydraulic brake system work in a car?
The mechanical brake system in your car is hydraulic, which means fluid in the brake system controls how the brakes are applied. When the brake pedal is pressed, the brake fluid is pressurized in the brake lines and hoses. The pressure in the brake hoses forces a piston in the brake calipers to extend.
What is the function of the brake light switch?
The brake light switch serves two major functions. First, it turns on the brake lights when a driver presses the brake pedal. Second, it sends the signal to the vehicle computer that brakes are applied. A car with a faulty brake light switch is UNSAFE to drive.

What happens when you close the parking brake warning switch?
If there is a problem with the parking brake, the switch will close. This circuit normally has a lower resistance, which causes the Brake Warning Light to shine brighter while the parking brake is applied.

What to do if you have a bad parking brake?
Even if you suspect the Brake Warning Light is brighter, it is still a safety concern driving with a bad parking brake. If your warning light is illuminated on your dashboard, contact the professionals at YourMechanic for further advice.
