That's the lock-out that keeps you from moving the transmission out of Park without the brake being down. It should have done that its entire life (my '95 Mystique did), and isn't anything to worry about. The codes being read wouldn't have had anything to do with it.
It sounds like you need to bleed the system of air.
Pads on front, drums or pads at rear. Ask at a good auto part store with year of car
To change the rear brakes on a 2000 Mercury Mystique, start by safely lifting the vehicle and removing the rear wheels. Next, remove the brake caliper bolts and slide the caliper off the rotor, then take out the old brake pads. Replace them with new pads, ensuring proper orientation, and reattach the caliper. Finally, reassemble the wheel and lower the vehicle before testing the brakes to ensure they function correctly.
I just paid $500.00 to replace all brake pads and the front rotors
Any Auto Parts store can provide you with this information.
The Mercury Mountaineer has hydraulic brakes, not air brakes.
This is the locking mechanism that prevents you from shifting from park without depressing the brake pedal or pressing the release button to the right of the gear shifter. This is the locking mechanism that prevents you from shifting from park without depressing the brake pedal or pressing the release button to the right of the gear shifter.
The 2001 Escape, with the gear shifter on the steering column, has an interlock solenoid located by the shifter assembly. The purpose is to lock the shifter in PARK until you depress the brake pedal. This is to prevent "sudden acceleration" where you engage the transmission with the brake off and the car shoots forward or backward. When you press the brake pedal a switch is closed that turns on the break lights and activates the solenoid, generating a magnetic field that withdraws the interlock pin, allowing you to move the shifter out of Park and into Drive or Reverse. The solenoid can make a clicking noise. We never noticed the clicking sound in our 2001 Escape until this mechanism had begun to fail, locking the shifter in Park regardless of the position of the brake pedal.
The brakes may make a clicking noise if the caliper is going bad. I just changed the brakes and the rotors and discovered my car was making a clicking noise. The garage I took it to replaced the caliper, so now it doesn't make the noise anymore.
A 1991 mercury topaz has drum brakes on the rear wheels.

Conventional drum brakes.
