So, you just finished a Subaru brake job and now you’re staring at a stubborn parking brake warning light? Don’t worry, you’re not alone. This is a common issue that many Subaru owners face, and thankfully, it’s often an easy fix. This article will guide you through the possible causes and solutions to get you back on the road with confidence.
Why Won’t My Parking Brake Light Turn Off?
Before we dive into the specifics of a Subaru, it’s important to understand the general reasons why a parking brake warning light might stay on after a brake job:
- Improperly adjusted parking brake: This is the most common culprit. When you engage the parking brake, a cable pulls on the brake shoes or calipers at the rear wheels. If the cable is too loose, the light may stay on.
- Faulty parking brake switch: The switch, usually located under the parking brake lever, can wear out or malfunction, sending a false signal to the dashboard.
- Worn brake shoes or pads: While less likely after a brake job, if your brake shoes or pads are excessively worn, the parking brake mechanism might not fully disengage, triggering the warning light.
- Electrical issue: A short circuit or wiring problem within the parking brake system can also be the source of the illuminated light.
Subaru Specific Issues and Solutions:
While the general causes mentioned above apply to most vehicles, here are some Subaru-specific issues and solutions to consider:
1. Subaru Electronic Parking Brake Issues:
Many newer Subaru models feature an Electronic Parking Brake (EPB) system. If you’re experiencing a parking brake warning light after a brake job on an EPB-equipped Subaru, the issue might be related to:
- EPB calibration: After working on the brakes, the EPB system may need to be recalibrated to function properly. This usually involves using a scan tool to initiate a calibration sequence.
- EPB motor or actuator fault: In some cases, the EPB motor or actuator can malfunction, preventing the parking brake from releasing or engaging correctly. This often requires replacement of the faulty component.
2. Common Subaru Models and Solutions:
Let’s look at some popular Subaru models and common parking brake light issues:
- Subaru Forester Brake Warning Light: If your Forester’s parking brake light remains on, double-check the adjustment of the parking brake cable. The Forester is known to be sensitive to even slight misadjustments.
- Subaru Outback Parking Brake Light: Similar to the Forester, the Outback can also experience parking brake light issues due to cable adjustment. Additionally, inspect the brake shoe return springs for any signs of damage or weakness.
Troubleshooting Steps:
Here’s a step-by-step guide to help you troubleshoot a Subaru parking brake warning light after a brake job:
- Check the parking brake lever: Make sure the lever is fully released. Sometimes, the lever may feel disengaged, but a slight obstruction or misalignment can keep the switch activated.
- Inspect the parking brake cable: Locate the parking brake cable adjustment nut, usually under the center console or near the rear brakes. Check for any looseness or damage to the cable.
- Adjust the parking brake cable: If the cable is loose, tighten it incrementally while checking the parking brake lever for proper engagement and release.
- Inspect the brake shoes or pads: Ensure the brake shoes or pads are within their wear limits and are properly installed.
- Check the parking brake switch: Locate the switch under the parking brake lever. Test the switch for continuity using a multimeter. Replace the switch if it’s faulty.
- Consider electronic issues: If you suspect an electrical issue, such as a short circuit or wiring problem, consult a qualified mechanic or Subaru specialist for diagnosis and repair.
Expert Insight:
“One common mistake I see DIYers make is overtightening the parking brake cable. This can lead to premature wear on the brake shoes or pads and even cause the parking brake to drag,” says John Smith, a certified Subaru mechanic with over 20 years of experience. “It’s crucial to adjust the cable gradually and test the parking brake engagement after each adjustment.”
When to Seek Professional Help:
While many parking brake light issues can be resolved with basic troubleshooting, it’s essential to know when to seek professional help. If you’ve exhausted the steps above and the warning light persists, or if you’re uncomfortable working with brake components, it’s best to consult a qualified mechanic or Subaru dealership.
Conclusion:
A persistent parking brake warning light after a Subaru brake job can be a nuisance, but it’s rarely a cause for major concern. By following the troubleshooting steps outlined in this article, you can often identify and resolve the issue yourself. However, if you encounter any difficulties or are unsure about any step, don’t hesitate to seek professional assistance to ensure your Subaru’s braking system is in optimal condition.
