- For the 1981-85 Country Squire, a new aftermarket switch is a reliable and budget-friendly repair.
- Replacement is a simple DIY job that most owners can complete in under 30 minutes.
- Always check and replace the small plastic bushings on the pedal pin for a lasting repair.
Signs of a Failing Brake Light Switch
A brake light switch failure is usually straightforward to diagnose. The most common symptoms point directly to the brake light system. If you experience any of these issues, you should inspect the switch immediately.
- Brake Lights Don't Turn On: This is the most dangerous symptom. If the switch fails in the open position, it will never complete the circuit, and your brake lights won't illuminate at all when you press the pedal.
- Brake Lights Stay On: The switch can also fail in the closed position, causing the brake lights to remain on even when your foot is off the pedal. This can confuse other drivers and will drain your battery when the car is parked.
- Intermittent Brake Lights: Your brake lights might flicker or only work when you press the pedal hard or wiggle it. This indicates an internal problem with the switch or a poor connection.
Choosing the Right Aftermarket Switch
For a vehicle like the 1981-1985 Country Squire, finding a New Old Stock (NOS) OEM Ford part can be difficult and expensive. Fortunately, the brake light switch is a simple, non-electronic component, and high-quality aftermarket replacements are widely available and perfectly suitable. Brands like Duralast and Standard Motor Products (SMP) offer reliable replacements that meet or exceed original specifications. Given the low cost and high reliability of these parts, a new aftermarket switch is the most practical and cost-effective solution for nearly all owners.
Pro Tip: Check the Bushings
The switch on these Fords often uses small nylon bushings to attach to the brake pedal pin. These bushings can become brittle and disintegrate over time, causing the switch to move improperly and fail to activate correctly. It's a good idea to replace these inexpensive bushings when you replace the switch.
DIY Replacement Guide
Replacing the brake light switch is a job most owners can do at home in under 30 minutes with basic tools.
- Locate the Switch: The switch is mounted on the brake pedal support bracket, just above the pedal itself. You will need to look up under the dashboard from the driver's side footwell.
- Disconnect Power: It's a good practice to disconnect the negative battery terminal before working on any electrical components.
- Unplug the Connector: Carefully unplug the electrical connector from the back of the switch.
- Remove the Old Switch: The switch is held onto a pin on the brake pedal arm by a hairpin-style retainer clip. Remove the clip with pliers, then slide the switch, along with any washers or bushings, off the pin.
- Install the New Switch: Slide the new switch onto the pin, making sure any bushings and washers are in the correct order. Secure it with the new retainer clip.
- Reconnect and Test: Plug the electrical connector back in and reconnect the battery. Have a helper stand behind the vehicle to confirm that the brake lights turn on when you press the pedal and turn off when you release it.

Frequently Asked Questions
Can a bad brake light switch cause my car not to start?
No, on this specific vehicle, the brake light switch is not tied into the starting circuit. Its primary functions are to operate the brake lights and disengage cruise control.
Are any special tools required for the replacement?
No special tools are needed. A pair of needle-nose pliers to remove the retainer clip is typically all that's required, and sometimes you can do it by hand.
My brake lights only work if I press the pedal very hard. Is this the switch?
This is a classic symptom of a worn or misaligned brake light switch. The internal contacts are not making a connection until maximum pressure is applied. Replacing the switch and its bushings should solve the problem.
Were there any recalls for the brake light switch on this car?
No, searches of the NHTSA database did not show any specific recalls for the brake light switch on the 1981-1985 Ford Country Squire. Recalls found were for much newer Ford models.
