When you stop and feel a pulsation in the front wheels which you will feel in the steering wheel, this is a sign you have a wrapped rotor. But you mention it is worse when you turn on the A/C which would indicate your idle control motor may be bad. This increases the idle when the engine is loaded, as in the A/C on.
If you mean when you are coming to a stop, and press on the brakes, you feel a vibration- this most likely means that your brake rotors are warped and need to be turned. If you mean you are already at a full stop, in idle, and you press the brake and feel a vibration- it may mean a vacuum problem in the engine or something like that. So it depends- is it your brakes vibrating, you feel it in the pedal? Or is it your engine suddenly running rough and the whole front end of the car shakes?
Halogen fluid. When it gets low this can happen.
The Vehicle shakes because of the virbration produced by the engine at the stop sing
THe brakes rarely need to stop. But the brakes can be used to make the bike stop.
The water gets into the brakes and when you stop there is less friction.
If it shakes only when the brakes are applied, its the brakes. Just because they are "good" and stop the truck well doesn't mean they are balanced and wont cause a vibration.
Turn off the engine and let the vehicle 'coast' to a stop - assisting with brakes if necessary.
Brakes use friction to stop a car.

you change the brakes,check brakes fluid,bleed the brakes why is hard to stop in a 1988 sliverado?
squeaking from your brakes could mean they are needing replacement, manufacturers build in metal tabs to the brake pads so when they get low they squeak, have them checked before too long, it gets costly if you wait.
Yes, that is the purpose of brakes.
