Hot Brakes | Tips & Resources

Prepare for the Trip

  • Check brake function and adjustment before descending.
  • Maintain a low speed in low gear, and use flashers to warn other vehicles of your reduced speed.
  • Do not ride the truck’s brakes; this will cause overheating and possible loss of brake system.
  • Consider Jake Brakes (engine compression brakes) to control the speed of a heavy truck, but the best practice is to use low gears to avoid overheating brakes.
  • Keep brakes cool by pulling into brake check stations, or onto the shoulder of the road, if you can locate a safe spot.

  • There is not a fee, penalty or fine for using runaway truck ramps.
