The 2014 Mercedes E350 parking brake issue, where the brake won't release, is a common concern among owners. This guide will provide practical solutions and troubleshooting steps to help you resolve the problem effectively.

Understanding the Problem

The parking brake on the E350 may become stuck due to various reasons, including infrequent use, cold weather, or mechanical issues. When the parking brake fails to release properly, it can trigger warning lights on the dashboard and lead to frustration when trying to drive.

Common Causes

  • Infrequent Use: If the parking brake is not used regularly, it may become sticky or jammed.
  • Cold Weather: Low temperatures can cause components to contract and stick.
  • Mechanical Failure: Issues with the parking brake assembly or cables may prevent proper operation.
  • Weak Battery: A low battery can affect electronic systems, including the parking brake.

Quick Fixes

Manual Release Technique

If your parking brake does not release:

  • Pull the Release Lever: Hold the release lever out while simultaneously using your foot to pull up on the pedal. This can help disengage a stuck mechanism.

Lubrication

Applying lubricant can often resolve sticking issues:

  • Use WD-40 or Lithium Grease: Spray lubricant around the parking brake mechanism. Allow it to penetrate for several minutes before attempting to operate the brake again. Regular maintenance with lubricant can prevent future issues.

Electrical Reset

If electronic components are involved:

  • Turn Off and Restart: Sometimes, simply turning off the engine and restarting can reset electronic systems. After restarting, hold the park brake switch for about 10 seconds before releasing it.

When to Seek Professional Help

If these quick fixes do not work, it might be time to consult a professional mechanic. Here are signs that professional help is needed:

  • Persistent warning lights even after attempting manual release.
  • Unusual noises when operating the parking brake.
  • If lubrication does not resolve the issue and you suspect mechanical failure.
