Is Your Capri's Brake Light Switch Failing?
On a classic car like the 1971-1978 Mercury Capri, electrical components can fail simply due to age, heat, and repeated use. The brake light switch is no exception. The most common signs of a failing switch are brake lights that don't come on at all, stay on constantly and drain your battery, or work intermittently. Since this part is essential for safety, it's important to address these symptoms immediately.
Safety First: A Critical Repair
Driving without functional brake lights is illegal and extremely dangerous. Other drivers will have no warning when you are slowing or stopping, dramatically increasing the risk of a rear-end collision. If you suspect your brake light switch has failed, do not drive the vehicle until it has been repaired.
Choosing the Right Aftermarket Switch
For a vintage vehicle like the Capri, finding original Ford (OEM) parts can be difficult and expensive. New Old Stock (NOS) parts may be available from specialty sellers, but they are often costly and carry no warranty. Luckily, the aftermarket provides reliable and affordable solutions. The primary brand available for this application is Standard Ignition (Standard Motor Products). Standard is a well-known and trusted manufacturer that has been producing quality replacement parts for decades. For a simple, non-computerized component like this switch, a new aftermarket part from a reputable brand like Standard offers the best combination of quality, reliability, and value.
Estimated Replacement Cost
The cost to replace the brake light switch is very reasonable, especially if you do the work yourself. The part itself is inexpensive, and labor is minimal.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (Standard Ignition) | $26.51 |
| Shop Labor | $50 - $100 |
| Total Estimated Cost (Installed) | $76 - $127 |
DIY Installation
Replacing the brake light switch is a straightforward job that most DIY mechanics can complete in under 30 minutes with basic hand tools. The switch is located under the dashboard, attached to the brake pedal assembly. The process involves disconnecting the battery, unplugging the electrical connector, and removing the switch from its bracket. This is an excellent project for a beginner looking to save on labor costs.
Frequently Asked Questions
Where is the brake light switch located on a 1971-1978 Capri?
The brake light switch is found under the driver's side dashboard. Look for the top of the brake pedal arm, and you will see the small switch mounted on a bracket with a wiring connector attached to it.
Is it difficult to replace the brake light switch myself?
No, this is considered an easy repair. It typically requires no special tools and can be done in less than half an hour. You will be working in a tight space under the dash, which can be awkward, but the steps are simple: disconnect the electrical plug, unclip or unscrew the old switch, and install the new one.
My brake lights are stuck on. Is that the switch?
It is very likely the cause. A brake light switch can fail in the 'closed' or 'on' position, causing the lights to stay illuminated constantly. This will drain your battery if not addressed. Before replacing the switch, also check that the brake pedal is returning to its fully upright position and hasn't become misaligned.
Are there any recalls for the brake light switch on the 1971-1978 Capri?
Searches of the NHTSA database did not show any recalls specifically for the brake light switch on the 1971-1978 Mercury Capri. There was a recall for the headlight switch on some model years, but not the brake light switch. There were also large-scale Ford recalls for brake pressure switches related to cruise control in later years and different models, but these do not apply to this specific part or vehicle range.
