Why is the parking brake light on in my Ford Explorer?
The parking brake light in a Ford Explorer usually means either the parking brake is engaged or there’s a fault in the braking system or its electronic control. If it stays lit after you’ve released the brake, you should investigate promptly to avoid brake damage or reduced stopping power.
Possible reasons the light is on
Below are common reasons you might see the parking brake light on a Ford Explorer. The exact cause depends on whether the light comes on while you’re parked, or while you’re driving.
- Parking brake is still engaged or not fully released
- Electronic parking brake (EPB) system fault
- Low brake fluid or a hydraulic pressure issue in the braking system
- Worn brake pads or a faulty brake pad wear sensor
- ABS or stability control (ESC) fault affecting the braking warning circuit
- Faulty brake light switch or wiring harness
If any of these apply, or the light remains on after attempting to release the brake, a professional inspection is recommended to prevent brake damage or unsafe driving conditions.
What to do next
If you notice the light is on, follow these steps to diagnose and address the issue. The goal is to determine whether it’s something you can safely handle or if it requires a shop visit.
- Make sure the parking brake is fully released and not dragging. If the light goes off with a complete release, the issue may be resolved.
- Check the brake pedal feel. A spongy or sinking pedal can indicate a hydraulic problem or air in the lines.
- Inspect the brake fluid level in the reservoir. Low fluid can trigger warning lights and may indicate a leak or worn components.
- Look for visible signs of leaks around brake lines, calipers, and the master cylinder, and check for excessively worn pads or rotors.
- Use an OBD-II scanner or have a shop perform a brake-system diagnostic to pull codes related to EPB, ABS, or brake-fluid warnings.
- If the light remains on after releasing the brake or you see other warning lights, schedule a diagnostic with a Ford dealer or qualified mechanic promptly.
Addressing the issue sooner can prevent further damage and help ensure reliable braking.
Safety considerations and driving tips
Follow these safety guidelines to minimize risk if you’re dealing with a parking brake warning while on the road.
- If the light comes on while driving, pull over safely and inspect for signs of dragging brakes, unusual heat, or smells from the wheels.
- Avoid driving long distances with a suspected brake issue; have the vehicle towed if necessary.
- Do not drive with the electronic parking brake engaged or attempting to drive through the brake-warning condition, as this can overheat pads and rotors.
- Seek roadside assistance or a tow to a service center if you’re not able to diagnose and resolve the issue safely.
Prompt attention helps protect you and others on the road and can prevent costly brake repairs down the line.

What the Electronic Parking Brake (EPB) does
Many newer Ford Explorers use an electronic parking brake that activates with a switch or push button. The EPB automatically applies the rear brakes and can interact with ABS/ESC systems. A fault in the EPB system or its wiring can trigger a warning light even when the brakes appear released.
Diagnostics and when to seek professional help
Because EPB and brake systems share sensors and controllers, a codes-based diagnostic is often needed to identify the root cause. A dealership or qualified technician can read the ABS/EPB fault codes and inspect the hydraulic and electrical components to determine whether the issue is mechanical, hydraulic, or electronic in nature.
Summary
In a Ford Explorer, a parked or visible parking brake light usually signals either that the brake is engaged or there is a fault in the braking system, EPB, or related sensors. Start by ensuring the brake is fully released, check fluid and pedal feel, inspect for leaks and wear, and read any diagnostic codes. If the light remains on or you notice unusual braking behavior, arrange a professional inspection promptly to maintain safe operation.
