  Q: How to replace the Brake Light Switch on Chevrolet Classic?

  A: Before changing the stop lamp switch you need to detach the left instrument panel panel and disconnect connections 3 and 4 to the switch. Adjust the stop lamp switch counter-clockwise to its travel stop then pull it out of the retainer to unhook it. Fit the stop lamp switch into the retainer while keeping the Brake Pedal connected to the power booster rod and maintaining its original position throughout the process without pressing the brake. Press the stop lamp switch into the retainer until its plunger fully enters the switch barrel by about 2-3 pounds of pressure to stop the Brake Pedal bracket from misaligning the switch. Move the stop lamp switch until it reaches the travel stop then push a thickness gauge between the switch barrel and Brake Pedal bracket for 0.0 and 2.0 mm (0.0 - 0.78 inches). Attach electrical cables to the stop lamp switch before repositioning the insulator panel for the left side.
