1. Preparation

Tools Required: Socket set, wrench set, brake cleaner, OBD-II scanner
Ensure the vehicle is parked on a flat surface and the ignition is off. Engage the parking brake for safety.

2. Inspect and Clear Obstructions

Sub-steps:
- Remove any floor mats or obstructions that may be interfering with the brake pedal.
- Check the brake pedal pivot point for dirt or debris; clean as necessary with brake cleaner.
- Ensure that the brake light switch is not misaligned or jammed.
