In all cars and most trucks HYDRAULIC pressure is used to apply the brakes. In an air brake system such as is found on medium and heavy duty trucks the air is actually released to apply the brakes.
modern cars have a brake pressure equalizer on them. sounds like this valve is not working correctly.could also be a bad caliper on that wheel
Stomp the brake pedal and do not release heavy pressure. Let the anti-lock brakes prevent the skid, as you steer around the obstruction if possible. The brake pedal will vibrate and you will hear some noise, but just keep pushing on the brake.
Air pressure within the air braking system of a tractor-trailer (or large truck) is what prevents the brakes from being applied. The pressure of the air pushes back a large spring at each wheel. The large spring will apply the brakes when there is no pressure in the system. When the driver steps on the brake pedal, air is released out of the system and the brakes are applied. When the driver's foot comes off the brake pedal, air is quickly pumped back into the system and the brakes are released. Disconnecting the air line has the same effect on the trailer's brakes. Air is released from the system, and the brakes are applied. It is not the brakes themselves that lock. Application of the brakes causes the wheels to lock.
The piston is forced out of the caliper by the pressure of the brake fluid. This pushes the brake pads against the rotor, in turn stopping the vehicle.
A piston on each end of the wheel cylinder pushes outward when the brakes are applied. This pushes the brake shoes against the brake drum and stops the vehicle. The pistons are forced out by the pressure of the brake fluid inside the wheel cylinder when you apply the brakes.

The pumping and releasing of brakes by the unit is brake pressure modulation
HA NO BRAKES!!!!

The hold off diaphragm on an air brake system is at the bottom of the maxi-spring within the hold off chamber of spring brakes. Air from the system pushes against the hold off diaphragm and prevents spring pressure being applied to the push rod until the air supply is released.
No. The brakes are applied manually. A brake band squeezes a brake drum.
