The Pontiac Fiero, a beloved mid-engined sports car, occasionally throws up a few head-scratchers for its owners. One such puzzle is the dreaded “e-brake warning” light. While this might seem straightforward at first, several factors beyond just an engaged parking brake can trigger this warning. This article dives into the common causes of the Fiero e-brake warning light and provides a step-by-step guide to help you diagnose and resolve the issue.

Understanding the E-Brake Warning System
Before we jump into troubleshooting, it’s crucial to understand how the Fiero’s e-brake warning system works. Essentially, it’s a simple circuit: when the parking brake is engaged, a switch closes, completing the circuit, and illuminating the warning light on your dashboard. Similarly, when the parking brake is released, the switch opens, breaking the circuit, and turning off the light.
However, complications arise because this circuit is also linked to your brake fluid level sensor. If the system detects low brake fluid, it triggers the same warning light, often accompanied by a chime. This dual-purpose functionality means a glowing e-brake warning light might not always indicate a problem with the parking brake itself.
Common Causes of a Fiero E-Brake Warning
Here are the most common culprits behind that persistent e-brake warning light:
- Engaged Parking Brake: This might seem obvious, but sometimes the simplest solution is the right one. Double-check that your parking brake is fully released.
- Low Brake Fluid: As mentioned earlier, low brake fluid is a common trigger. Check your brake fluid reservoir; if it’s low, there might be a leak in your braking system, which needs immediate attention.
- Faulty E-Brake Switch: The switch located on the parking brake mechanism can wear out or malfunction, sending a false signal to the warning light.
- Wworn Brake Pads: While not directly related to the e-brake system, severely worn brake pads can cause the brake fluid level to drop, indirectly triggering the warning light.
- Loose or Damaged Wiring: Over time, the wiring connecting the e-brake switch, brake fluid level sensor, and the dashboard light can become loose, corroded, or damaged, leading to faulty signals.
Troubleshooting the Fiero E-Brake Warning Light
Now that you’re familiar with the potential causes, let’s outline a systematic approach to diagnose the problem:
Step 1: Check the Parking Brake
Begin with the basics: ensure your parking brake is fully disengaged. Sometimes the lever might feel disengaged, but the brake might still be slightly applied.
Step 2: Inspect the Brake Fluid Level
Locate the brake fluid reservoir – it’s typically a translucent plastic container near the firewall. Check the fluid level against the “Min” and “Max” markings. If it’s low, add the correct type of brake fluid recommended for your Fiero. However, simply topping off the fluid isn’t a solution if you have a leak, which will need to be addressed by a mechanic.
Step 3: Inspect the E-Brake Switch
Locate the e-brake switch – it’s usually mounted near the base of the parking brake lever under the dashboard. With the parking brake disengaged, try pressing and releasing the switch manually. If the warning light flickers or changes state, the switch itself might be faulty and need replacement.

Step 4: Inspect Brake Pads
While visually inspecting brake pads requires removing the wheels, it’s a crucial step if you suspect worn pads. If your brake pads are worn down to the metal indicators, it’s time for a replacement.
Step 5: Examine the Wiring
Carefully inspect the wiring harness connecting the e-brake switch and brake fluid level sensor for any signs of damage, loose connections, or corrosion. Repair or replace any damaged wiring.
Seeking Professional Help
If your DIY troubleshooting doesn’t resolve the issue, it’s best to consult a qualified mechanic specializing in Pontiac Fieros. They have the expertise and tools to diagnose and repair complex electrical or brake system issues.
Expert Insight
“Many Fiero owners often overlook the interconnected nature of the e-brake warning system,” says John Peterson, a seasoned automotive electrician with over 20 years of experience. “While the warning light itself is simple, the underlying causes can range from a loose wire to a serious brake fluid leak. That’s why a methodical approach to troubleshooting is crucial.”
Conclusion
The e-brake warning light in your Pontiac Fiero is a crucial safety feature, and ignoring it can lead to potentially dangerous situations. By understanding the common causes and following the troubleshooting steps outlined in this guide, you can confidently address this issue and keep your Fiero running smoothly and safely on the road.
