Engine stalling when applying brakes is usually indicative of a leaky brake booster. The brake booster uses and stores engine vacuum while driving to assist your braking effort (power brakes). When the booster's air diaphragm is leaking air, applying brakes causes a substantial vacuum leak in the intake manifold, causing the engine to stall.
Hope that doesn't happen on a busy road.
Kinetic friction is the force that stops a train when the brakes are applied
The driver suddenly applied the brakes.
no
The answer depends on the mass of the train and the force applied by the brakes.
only thing i know that will make brkes grind, is worn out brakesmaybe have em checked at a different mechanic
Friction
They get hot.
Hey Brad No, They should be ok. GoodluckJOe
Assuming we are talking about "S" cam air brakes on a truck, check the angle at the end of the slack adjuster to the actuator rod coming out of the air brake can when brakes are applied, it should be 90 degrees, if the slack adjuster is manual adjust it with the brakes not applied and then test again. If they are automatic slack adjusters and you do not have 90 degrees with brakes applied it is worn out or not installed correctly.
they're so heavy that it takes the brakes some time to dissipate all that moving energy.
This is probably due to worn brake rotors on the brakes, if there is no vibration when driving then this will be the cause.
