Prevents brakes from locking by pulsating the pressure when you apply firmly so they don't grab.
The friction caused by the brakes causes the car to decelerate. This negative acceleration, in turn, causes a force to be applied to all those in the car. This is the lurch you feel.
They are equipped with a "telltale" warning that shrieks when the brakes are applied, with the brake pads are too low and need replacing.
They are warm because the friction makes the molecules in the brakes move faster, which causes it to warm up.
because the alignment is off Warped or out of round brake rotors/drums.
apply your brakes gently while accelerating at the same time
Check the brake fluid reservoir, it may be low on brake fluid indicating it is time to have the brakes inspected.
One possiblity could be the power brake booster is shot. When you apply the brakes it creates a large vacuum leak, enough to stall engine.
Worn bushes or warped brake rotor. Replace faulty item.
Either warped rotors or drums can cause pulsating. Apply the parking brake slowly while going about 15mph and see if t pulsates. If it does, it is the drums that need turning. If not, it is the rotors that need turning.
Time for new brakes or adjustment.
