Student Reading Guide

How to Perform a Brake Line Inspection

  • Examine all brake lines and hoses. This should be part of every vehicle inspection.
  • Begin at the master cylinder and proceed through the entire system following each line and hose.
  • Look especially at the lines most exposed to road conditions. Lower lines and lines that are run under the vehicle can be hit by obstacles and debris on the road.
  • Look for leaks.
  • Look for corroded or rusted lines.
  • Look for dented or kinked lines.
  • Look for cracked or bulging hoses.
  • Look for abrasions where the line or hose is worn or scraped.
  • Inspect brackets, fittings, and hold downs.
