Preliminary Inspections

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  1. Visually inspect easily accessible brake system components for obvious damage and/or leaks which may indicate that the vehicle should not be driven until further inspections have been completed.
  2. Inspect the brake master cylinder reservoir fluid level and adjust only if necessary for brake system road testing. Refer to Master Cylinder Reservoir Filling .
  3. Inspect the tire inflation pressures and adjust as necessary.
  4. Inspect the tire tread patterns to ensure that they are the same or very similar, especially per axle.
  5. Ensure that the vehicle is not loaded unevenly prior to brake system road testing.
