brakes are the braking system
It could be a part of the control system
It has a hydraulic system in the braking system
ABS brakes are not spongy. If you have spongy brakes the reason is that there is air in the system. You need to have your brakes bled.
S-cam brakes.
Yes.... the brakes will make a "metallic" sound when the brakes are getting worn.
A brake system brakes.
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.
faulty master brake system
were abs anit-lock brakes system
It's a dual circuit air brake system. Most use S-cam foundation brakes, although some use disc brakes or piston brakes.
The brakes will remain on, air pressure is required to release the brakes
The service brake is the one which applies the brakes - the emergency brake system is the system which releases the spring brakes.
the most probable cause is, there is air in system, bleed brakes
Disk brakes adjust themselves as they wear. Drum brakes have an automatic adjustment built into the brake system. When you back up and stop they automatically adjust themselves. If you remove the drum you will see the adjustment mechanism.
