In general they SHORTEN your stopping distance as they can apply more force to the breaks.
No you lose air pressure .
Soft brakes are caused by moisture or air in the brake lines. This reduces the pressure in side the system and greatly reduces its stopping power.
One - which needs to be on the brake pedal! Apart from the car's speed, the stopping distance will depend on the mass of the car, the condition of the brakes, the condition of the tyres - the air pressure and tread, the road condition, the driver's response.
Air stuck in the brake lines cause the peddle to feel "spongy". Your braking distance will dramatically increase with air in the system. When you apply the brakes in a vehicle that has no air in the system, that pressure added with the pressure from the master cylinder presses the brake pads against the rotor or drum causing you to stop. When there is air in the brake system and you apply the brakes some of that pressure is used up by compressing the air in the system and the rest is trying to stop the vehicle.
No, they use air pressure or actually the lack of air pressure to stop the vehicle. The brakes are fully on until pressure builds up in the tank releasing the brakes. When you push the brake pedal this removes air from the system and applies the brakes.
We would need to know what type of brakes you have... S-cam air brakes, air disc brakes, air piston brakes, air wedge brakes, hydraulic drum brakes, hydraulic disc brakes... they're all different.
Air brakes are just as effective as a standard set of brakes. The advantages to air brakes are that you do not have to worry about leaking brake fluid.
Compressed air.
The Mercury Mountaineer has hydraulic brakes, not air brakes.
The two major factors are; friction between tires and road; friction between brake pads and rotors. Wind speed plays a small role that is usually much less of an effect than the aforementioned.
George Westinghouse invented the air brakes
No. Hydraulic brakes can be either drum or disc brakes, and these two brake types are available as air brakes and air-over-hydraulic systems, as well.
