- Replacement is a simple, beginner-friendly DIY task that takes less than 30 minutes.

Is Your Ford Expedition's 'BRAKE' Light Lying to You?
If you're driving your 2005-2014 Ford Expedition and the red 'BRAKE' warning light on your dashboard is on, but you know for a fact the parking brake is released, you likely have a faulty parking brake switch. This is a common issue for these trucks as they age. The switch can wear out, get stuck, or the internal contacts can fail, causing it to send a constant 'on' signal to your dash.
Check This First!
That same 'BRAKE' light is also designed to warn you about low brake fluid. Before you buy any parts, pop the hood and check the brake fluid reservoir. If it's low, top it off with the correct fluid type and check for leaks. If the fluid level is fine, the parking brake switch is the next logical culprit.

- 'BRAKE' light stays on: The most common symptom is the dash light remaining illuminated even after the parking brake pedal is fully released.
- Intermittent 'BRAKE' light: The light may flicker or turn on and off as you drive, especially when going over bumps. This happens as the faulty switch makes and breaks contact randomly.
- 'BRAKE' light won't turn on: Less commonly, the switch can fail in the 'off' position, meaning the warning light will never come on, even when the parking brake is engaged.
Choosing the Right Aftermarket Switch
For a simple part like a parking brake switch, you don't necessarily need to pay dealership prices for an OEM Motorcraft part. A quality aftermarket switch will perform just as well. The key is choosing a brand known for its electrical components.
- Rostra Powertrain: Rostra is a well-established manufacturer of automotive electronics. Their parts are designed as direct-fit OE replacements, offering a reliable and affordable solution without the OEM price tag.
- Other Aftermarket Options: Brands like Standard Motor Products (SMP) or Dorman also produce reliable replacement switches for this application.
Given the low cost and simple function, a reputable aftermarket part like the one from Rostra Powertrain is a smart choice for this repair. There is no significant performance or longevity difference that justifies the higher cost of an OEM part for this specific component.

Frequently Asked Questions
Can I still drive my Expedition with a bad parking brake switch?
Yes, you can. A bad parking brake switch does not affect the actual braking performance of your vehicle. However, the constant warning light can be distracting and, more importantly, it could prevent you from being alerted to a real brake fluid issue. It's best to fix it sooner rather than later.
Is this the same as the brake light switch?
No. The parking brake switch operates the dash warning light. The main brake light switch is located on the service brake pedal (the one you press with your foot to stop) and it controls your rear brake lights and the shift interlock. If your rear brake lights don't work or you can't shift out of Park, you should inspect the main brake light switch, 🎬 See this walkthrough for replacing the main brake light switch. not the parking brake switch.
Are there any recalls for this part?
No, there are no recalls or Technical Service Bulletins (TSBs) from Ford specifically for the parking brake switch on the 2005-2014 Expedition. Recalls for parking brakes on Ford trucks typically involve electronic systems on much newer models.
How do I replace the switch?
The switch is located on the parking brake pedal assembly under the driver's side dashboard. You will need to remove the lower dash panel for access. The switch is typically held in by a single screw or it twists into a bracket. Simply disconnect the electrical connector, remove the old switch, install the new one, and reconnect the wiring.
