If the vehicle is equipped with a separate hydro boost pump, it could be going bad. If the pump isn't supplying the proper pressure to the hydro booster then the electric motor will continue to run. there is also a relay beneath the hydro boost/master cylinder assembly that could be sticking. The motor is there to supply braking assist pressure when the engine powered pump is not running.

Where is the brake shift interlock solenoid?


Brake/Shift Interlock System The shift interlock system prevents the shifting from PARK (P) (when the ignition switch is in the RUN position) unless the brake pedal (2455) is depressed. The interlock system consists of an electrical solenoid mounted at the base of the steering column (3C529). If the ignition switch is in the RUN position, the solenoid has continuous power supplied unless the brake pedal is depressed.

Removal
  1. Remove steering column as outlined in Section 11-04A or Section 11-04B .
  1. Unclip wire terminal from solenoid.
  1. Remove insert plate and solenoid by removing three retaining screws.
  1. Pry off clip.

Installation
  1. NOTE: The clip which retains the solenoid to the insert plate should not be replaced for service. The clip's sole purpose is an assembly aid for the assembly plant. Position insert plate/solenoid assembly to the steering column and tighten the retaining screws.
  1. Install the steering column in the vehicle as described in Section 11-04A or Section 11-04B .

Can't shift out of park, no brake lights


This is a problem with the brake sensor lockout. Most likely it is out of place or broken and shorting. It is on the brake pedal lever.

How to change clutch slave cylinder 2004 ford transit


Locate the cylinder on the gearbox bell housing. Clamp the flexible fluid feed hose to the slave cylinder, reasonably close to the cylinder. Disconnect the feed pipe to the cylinder, remove the cylinder's location bolts, and remove cylinder. Reverse process for reinstallation.
Once installed, open up the cylinder's bleed nipple, attach rubber hose (preferably clear type) and feed into a clear bottle. Open the master cylinder's reservoir cap and brim with clean fluid (usually brake fluid DOT 4 will be fine, unless stated otherwise on the cap)
Now it's easier if you have help pumping the clutch pedal as you will have to depress the pedal and clamp the bleed nipple, raise the pedal. Depress the pedal and open the nipple. Close the nipple and release the pedal. Keep repeating this procedure whilst continually topping up the reservoir and until the fluid coming out of the bleed nipple is clean and free from any air bubbles.
On the final depression of the pedal, lock the bleed nipple, release the pedal and then pump it a few times and judge the feel and travel of the pedal.
If the pedal is still only close to the floor when operating the clutch, then you likely still have some air in the system and should repeat the above steps.
If adequate pressure is available and the clutch operates well, then your job is done.


Be aware that brake fluid eats into paint and many types of plastics over time, so once you are done, then rinse any areas with water only, which came into contact with any spilled fluid.


Tada! You've finished! Road test the vehicle to be sure of a good successful job. Recheck the fluid level after a few hours driving to make sure you haven't any leaks and aren't loosing fluid.

I have a 2001 ford taurus and every time i push the brake pedal my brakes dont brake right and sounds like air is leaking


Is the brake pedal getting harder to depress? Also have you had any work done on the vehicle immediately prior to this problem? If the pedal is getting harder to depress it could be a failing power brake booster if your car has one. Some ABS systems are different than others

96 F250 can't shift out of park


NOTE: Your vehicle is equipped with a

brake-shift interlock feature. This

feature prevents you from shifting

from P (Park) unless you have the

brake pedal depressed. (The ignition

must be in the ON position.) If you

cannot shift from P (Park) with the

brake pedal depressed:


1. Apply the parking brake.

2. Remove the key.

3. Insert the key and rotate one position
clockwise (ignition in the OFF position).

4. Apply the brake pedal and shift to N

(Neutral). (If the vehicle is shifted to P

(Park), you must repeat the previous steps.)

5. Start the vehicle.


If you need to shift out of P (Park) by using the

alternate procedure described above, it is

possible that a fuse has blown and that your

brakelamps may also not be functional.


WARNING

DO NOT DRIVE YOUR VEHICLE UNTIL

YOU VERIFY THAT THE BRAKELAMPS
ARE WORKING.

check fuse 13 based on the attached diagram.

If this fuse is bad replace it. If it is not bad, blows again, or continues to be stuck in park then you need a new brake interlock switch that can be found on the brake pedal up underneath the dash.mustang_guru_2.jpg

Abs brakes chirping noise, when pedal depressed,


worn out brake pads and slightly warped rotors. Most brake pads have small steel tabs that touch the rotor at a 90 degree angle when it is time for replacement. if you keep driving on the worn pads, it will stop chirping but that just means the tabs (also called wear indicators) have broken off and repair is about to get very pricey.

Sounds like the front calipers are not fully retracting properly. Check the front caliper operation while a friend pumps the brake pedal, the rubber lines could also be cracked and allowing air into the lines. Check brake fluid level.
