Notice:
Proper stoplamp switch adjustment is
essential. Improper stoplamp switch adjustment may
cause brake drag, heat buildup and excessive brake
lining wear.
1. Adjust the cruise control release switch (2) and
the stoplamp and Torque Converter Clutch
(TCC) switch (3) at the same time.
2. Adjust the cruise control clutch switch (4) or the
cruise control clutch anticipate switch (6) if
equipped after the clutch pedal is installed.
3. Depress the brake or the clutch pedal.

the bracket until the retainers on the switches
are fully seated:
• Cruise control release switch (2)
• Stoplamp and TCC switch (3)
• Cruise control clutch switch (4) or cruise
control clutch anticipate switch (6) if equipped.
Important: Apply the proper amount of force to the
brake pedal during adjustment.
• Too much force may damage' the vacuum
booster.
• Too little force may cause the brakes to drag.
5. Slowly pull the brake or clutch pedal rearward
with a force of 222 N (50 lbs) until clicking
sounds are no longer heard. At this point, the
retainers on the switches will be adjusted.
6. Measure the cruise control release switch (2).
7. Measure the stoplamp and TCC switch (3).
8. The switch contacts should be open at 25.4 mm
(1.0 in) or less of pedal travel. The switch contacts
should occur at the same time or before the
onset of braking. The brake pedal travel can be
up to 25.4 mm (1.0 in) before the cruise control
system disengages .
