|Replacing a brake
light switch is a simple procedure.
1. Remove the two wire connector at the
end of the switch. There are two plastic
clips that are released by squeezing them
with your fingers. Some connectors may
have their clips broken off but this
won't keep the connector from being used.
2. Remove the retaining clip from the end
of the mounting stud on the brake pedal.
3. Pull the switch away from the pedal
just enough for the outer nylon washer
and the outer end flange of the switch to
go past the mounting stud. The other side
of the switch end is cutout so that you
don't have to remove the master cylinder
push rod from the pedal. The push rod
fits inside between the two end flanges.
The switch will just pull down and out.
4. Slide the new switch up and into place
with the push rod between the two end
5. Push the switch toward the pedal onto
the mounting stud and reinstall the outer
6. Reinstall the retaining clip to the
hole in the end of the pedal mounting
7. Reinstall the two wire connector to
the switch and you are done.
If your connector's plastic clips are
broken off, you can still use the
connector. If you feel that the terminals
in the connector don't fit tightly on the
contacts of the switch, you can use a
small thin knife blade or screw driver
end to slightly bend the terminals inside
at the closed end of the terminals to
make them fit more snugly. Now you should
have properly working brake lights when
you push on the pedal.
Also remember that the two nylon washers
that mount onto the pedal mounting stud
are very important. These washers keep
the switch tightly in place and operating
properly. Without them, the switch is too
loosely fitting on the mounting stud and
won't operate properly. Often these
washers are lost or missing. They can be
purchased from National Parts Depot and
other Mustang parts vendors.
