REMOVAL & INSTALLATION
See Figure 1
Fig. 1: Exploded view of the brake light switch
1. Lift the locking tab on the switch connector and disconnect the wiring.
2. Remove the hairpin retainer, slide the brake light switch, pushrod and nylon washer off of the pedal. Remove the washer, then the switch by sliding it up or down.
On some vehicles equipped with speed control, the spacer washer is replaced by the dump valve adapter washer.
3. To install the switch, position it so that the U-shaped side is nearest the pedal and directly over/under the pin.
4. Slide the switch up or down, trapping the master cylinder pushrod and bushing between the switch side plates.
5. Push the switch and pushrod assembly firmly towards the brake pedal arm. Assemble the outside white plastic washer to the pin and install the hairpin retainer.
Don't substitute any other type of retainer. Use only the Ford specified hairpin retainer.
6. Assemble the connector on the switch.
7. Check brake light operation.
Make sure that the brake light switch wiring has sufficient travel during a full pedal stroke.

Thanx for the replies. After trying all that I could figure to try, I took it to the local mechanic. He replaced the inner spacer with a couple of washers. Works like a champ; He said the plastic spacer was worn to the point it would let the switch move on the arm causing a change of pressure on the spring loaded switch. Makes sense to me now that it's fixed.
