When you press on the brake pedal it touches the floor?
One of the more common causes for the brake pedal going to the floor is a loss of brake fluid. When you’re out of brake fluid, your brakes simply won’t work. This is pretty easy to diagnose: You should be able to see brake fluid underneath the car if there’s a leak in the system.
What does the brake pedal position sensor do?
The brake pedal sensor is a major contributor to optimize regenerative braking for HEV, PHEV and EV passenger cars. It provides precisely to the inverter, the range of brake pedal stroke where the regeneration could be maximized.
Does brake switch affect transmission?
The brake light switch on modern vehicles is no longer a simple switch used to turn on the brake lights. A bad brake light switch, for example, can trigger the ABS and traction control lights, but it can also prevent engine start or even transmission shifting.
