there is a bad earth on your car somewhere
it may need some brake fluid
The driver would need to step on the brake pedal when braking a vehicle equipped with anti-lock brakes. FYI, the driver would also need to step on the brake pedal when braking a vehicle that is NOT equipped with anti-lock brakes. Hope this helps.
you either don't have the brake fully dis-engaged or you need to have your brakes checked for wear.
If the vehicle has brakes on the steer axle (which any truck from 1975 and newer will have), they're using both the primary and secondary system - primary for the drive axle and trailer brakes, secondary for the steer axle brakes, and often for any additional lift axle brakes, as well.
motor brakes? parking brake is engaged? transmission malfunction?
If the light stays on when the emergency brake is not engaged, this indicates the brakes are getting low and need to be replaced.
a brake booster supplies power to the brake system. this takes the hard out of the brake pedal allowing brakes to work harder with less effort or pressure on pedal from the driver
You complete the written air brakes test, and perform your road test in a vehicle equipped with air brakes.
Your brakes are sticking could be either the brake caliper or the hose going to the caliper
Did you check the vacuum hose or did you refill the brake fluid?
Generally speaking for cars that have "disk brakes", friction slows the car. When the driver presses down on the brake pedal the brake calipers squeeze the brake pads against the brake rotor inside each car wheel causing the car to slow down by friction.
It's pretty much the same on any FMVSS 121-compliant vehicle. There's an anti-compounding valve in the brake system... if you press the brake pedal while the spring brakes are engaged, it dumps air, rather than allowing the combined application pressures of the spring brakes and the service brakes to act on the brakes. This protects the brake chambers, slack adjusters, and especially the S-cam housings.
