  Q: How to service and repair the brake pedal assembly on Mercury Grand Marquis?

  A: The service and repair of brake pedal assembly needs a battery ground cable disconnect as the first step. First remove the instrument panel close-out panel through the process of removing pushpins followed by turning the lamp counterclockwise. The service begins with removing the speed control deactivator switch and continues with removal of booster push rod retaining pin cover along with the retaining pin. First disconnect the brake pedal pin by removing the stoplight switch and washer followed by bushing and booster push rod. The brake pedal bracket bolt needs removal but must reach 30 Nm (22 ft. lbs.) when reinstalling it. Disengage the adjustable brake pedal drive cable attachment from the brake pedal and stoplight switch harness from the pedal bracket. The pinch bolt that connects the steering column lower yoke to the lower steering column shaft should be removed before discarding it but installing the new bolt with a torque of 28 Nm (21 ft. lbs.). Follow the removal of four brake pedal bracket nuts and detach the brake pedal and bracket before reinstalling them with 28 Nm (21 ft. lbs.) torque. An indexing step should always be performed on the adjustable pedal system whenever repair work takes place on the brake pedal assembly or the accelerator pedal assembly. Position the brake switch so that the closed opening faces the other direction from the brake pedal arm and the open side remains directed toward it. Reverse the removal steps while testing that the stoplights function correctly.

  Q: How to Ensure Proper Functioning of the Brake Pedal in a Mercury Monterey?

  A: Before servicing or repairing the brake pedal assembly start by moving adjustable pedals to the maximum forward extent. The steering column opening cover requires tightening to 8 Nm (71 inch lbs.) on its three bolts before removing the cover itself. The following installation step requires removal of two steering column opening reinforcement bolts followed by its removal while tightening to 8 Nm (71 inch lbs.). The first step is to disconnect the left-hand side demister duct after which technicians need to remove and securely set aside the steering intermediate shaft by tightening its upper bolt to 30 Nm (22 ft. lbs.). Separate the extra self-locking clips from both the cover and the clip itself. Remove the brake pedal position (BPP) switch together with booster rod along with bushing from the brake pedal. Lessen pressure on the accelerator cable from the accelerator pedal arm and the plastic plunger when steering vehicles with adjustable pedals. The adjustable pedal motor electrical connector must be disconnected at the top of the bracket when the vehicle has this feature enabled. First remove four brake booster nuts and tighten them to 25 Nm (18 ft. lbs.) reinstall them before unfastening the two upper brake pedal bracket bolts that need tightening to 25 Nm (18 ft. lbs.) as well. The brake pedal assembly along with bracket must be removed before you can finish the installation by doing the opposite of removal steps.
