Installation Guide

The following steps outline a straightforward installation process. For safety, ensure the vehicle is securely lifted and supported on jack stands before beginning.

1. Remove the Front Left Brake Caliper:
   • Detach the brake hose using a suitable wrench.
   • Unbolt the caliper mounting bolts.
   • Carefully slide the caliper away from the rotor.
2. Access the Brake Pad Wear Sensor:
   • Locate the small metal housing on the brake pad assembly.
   • Remove any retaining screws or clips securing the sensor.
3. Install the ABS 39657:
   • Align the new sensor with the mounting points.
   • Screw it into place, ensuring a snug fit.
   • Reconnect any electrical connectors if present.
4. Reassemble:
   • Position the caliper back over the rotor.
   • Secure the mounting bolts and reattach the brake hose.
   • Check for proper alignment and torque specifications.
5. Test the System:
   • Start the vehicle and observe the dashboard indicator.
   • If the warning light remains off, the sensor is functioning correctly.

Troubleshooting Common Issues

While the ABS 39657 is engineered for reliability, certain scenarios may cause false readings or failures. Below are common troubleshooting steps:

Dashboard Warning Light Ignites Immediately After Installation

Check that the sensor is correctly seated and all electrical contacts are clean. Reinstall if necessary.

No Dashboard Indicator When Pads Are Worn

Verify that the brake pads have reached the manufacturer’s wear threshold. If not, replace them before testing again.

Intermittent Warning Light

This may indicate a loose electrical connection or corrosion. Clean contacts and ensure secure mounting.

Maintenance Tips for Longevity

• Inspect the sensor housing annually for signs of wear or damage.
• Keep the brake system free from excessive moisture to prevent corrosion of electrical components.
• Replace the sensor if any part of it shows visible cracking or deformation.

Frequently Asked Questions (FAQs)

Is the ABS 39657 compatible with all Porsche Cayman/Boxster models?
