SOURCE: EMERGENCY BRAKE PEDAL GOES DOWN TO THE FLOOR WHEN ENGAGED

sounds like you have a worn set of park break shoes. they are located inside /behind the read rotors. if you remove the rotor and the shoes look fine then you can adjust them with the little star gear located on the bottom of the brake shoes.

SOURCE: Power brakes not working

No such thing as vacuum lines to the master cylinder. You do have a vacuum line on the brake booster (power assist). When you step on the pedal do you hear a whoosing sound down by your pedal. This is a leaking Booster. Needs replacement.

When you step on the brake does the engine rpm change. This is a leaking check valve (one way air valve).

SOURCE: brake pedal goes to floor by itself when truck is started

the vacuum booster for the master cylinder should be looked at. ive done this for over 20 years and i cant say ive ever heard of this. does this occur ONLY when the truck is started? do you have a pedal when the truck is off? please respond.

SOURCE: brake pedal goes to floor even when truck isnt on.

Did you bench bleed your master cylinder before you installed it? If not you may not be able to purge the air from it.

Car will not shift into drive when pressing brake pedal

Your BTSI (brake interlock shift system) is in faulty. When you pressed on the brake pedal, there is a voltage send to the BTSI solenoid which is supposed to unlock so you can shift. If you can verify that the brake switch send a voltage to the solenoid , the solenoid is the faulty part.

BRAKE LIGHTS STAYS ON. the swith isnt the problem.

If the car thinks the brakes are on, then the switch on the brake pedal lever under the dash is bad. But this switch is not the only switch you have. IF your system works like the Ford products I am use to, then another interlock is present to prevent you shifting out of Park without pressing the brakes.

If you are able to shift without your foot on the brake, you are still getting a signal to the second interlock with the trans. This means the brake pedal switch is saying your foot is pressing the pedal. Some cars are in the data base for Autozone.com. If you can register your car for free, most will have free wiring diagrams and fusebox layouts.

You may have a relay for brake lights on a Mercedes. Other cars usually do not because it affects reliability. But a stuck brake relay could keep the light circuit on, if equipped.

A better scanner can do brake functions and all you need to do is plug in the tester to the ABS port and see if the abs is identifying a problem. The cheaper scanners do not have this feature.

A remote possibility is that you have a bad Master cylinder and the pedal is not returning to the full upright position.

I hope my solution is helpful.

The car wont come out of park

The problem is with the shift interlock switch...the device which prevents the transmission from being shifted out of park without the brake pedal pressed. The switch is usually located somewhere under dash near steering column on column shift models and under the console on floor shift models. Have it replaced.

Cant change gear from park to drive

its a safety switch located either on the brake pedal support or the safety release located in the steering column.
you press the brake pedal and the switch sends power to the release, that allows you to shift the gear selector out of park.

Gear shift of f-150 is locked in park. The truck

Is the CHMSL ( Center High Mount Stop Lamp ) working ?
Is it a regular bulb, or did it get changed to a LED ?
If it is a functioning factory type bulb, the shift interlock solenoid is the cause.
Until you can fix the CHMSL or the shift interlock, you can turn the key to the run position ( do not start ), press and hold the brake pedal, shift into neutral, and then start the truck.
Your MY the shift interlock circuit and the brake lamp circuit are the same.
Usually the shift interlock stops working when the brake lamp fuse is blown, or if the bulbs are out ( truck does not see a load on the circuit ).
If LED tail lamps were installed without load resistors, the shift interlock circuit will not work ( looks like a burnt out brake lamp bulb )

Warning light on the dashboard

As far as the red light goes. You simply have a brake light bulb out.

The clicking is normal. Its the shift lock solenoid. When you press on the brake it lets you shift into gear.

Sheift lock

The term "shift lock" is the system that is in place to prevent the vehicle from being shifted out of Park into Reverse or Drive WITHOUT having the driver's foot firmly on the brake pedal. The brake light switch on the brake pedal closes a circuit that energizes a solenoid under the shifter. When the brake is applied, and the solenoid is energized, the shift lever is no longer "locked", and can be moved to the desired position.
The idea here stems from a phenonomon several years ago that dealt with the issue of "Sudden Intended Acceleration". What was happening here was, for some unknown reason, engines started developing high RPMS for no reason, and several accisents were reported due to this issue. The vehicle would accelerate "unintendedly", when putting into drive or reverse, and could hit something.
