The dreaded red parking brake warning light on your 2008 Range Rover Sport Supercharged can be a real headache. It can indicate several issues, from a simple engaged parking brake to more complex problems requiring professional attention. This comprehensive guide dives deep into the common causes, diagnostic procedures, and solutions for this frustrating warning light.
Understanding the Red Parking Brake Warning Light
The red parking brake warning light illuminates when the parking brake is engaged. This is normal behavior. However, if the light remains on even after disengaging the brake, it signals a potential problem within the system. This could involve low brake fluid, a faulty parking brake switch, or even issues with the vehicle’s electronic control modules. Don’t panic! This guide will help you navigate the process of identifying and resolving the issue.
Common Causes of a Persistent Red Parking Brake Warning Light
Several factors can trigger a persistent red parking brake warning light in your 2008 Range Rover Sport Supercharged. Let’s explore the most frequent culprits:
- Engaged Parking Brake: It seems obvious, but sometimes the parking brake isn’t fully disengaged. Double-check to ensure the brake lever is completely down.
- Low Brake Fluid: Low brake fluid levels can activate the warning light. Check your brake fluid reservoir and top it off if necessary. If the fluid level drops quickly, you may have a leak.
- Faulty Parking Brake Switch: The switch that detects the parking brake position can malfunction, sending incorrect signals to the vehicle’s computer.
- Worn Brake Pads or Rotors: While less common as a direct cause of the parking brake light, worn brake components can contribute to overall braking system issues, which might indirectly trigger the light.
- Electrical Issues: Problems with the wiring or connectors in the parking brake system can lead to faulty signals and illuminate the warning light.
- ABS Module Issues: The Anti-lock Braking System (ABS) module can sometimes malfunction and trigger various warning lights, including the parking brake light.

Solutions and Repairs
Depending on the diagnosed cause, the solution may range from a simple fix to a more complex repair:
- Top off Brake Fluid: If the brake fluid is low, topping it off might resolve the issue. However, persistent low fluid indicates a leak that needs professional attention.
- Replace Parking Brake Switch: A faulty parking brake switch often requires replacement.
- Repair Wiring or Connectors: Damaged wiring or connectors need repair or replacement by a qualified technician.
- Address ABS Module Issues: ABS module problems might require specialized diagnostics and repair or replacement.
