When Driving A Car On A Downhill

when driving a car on a downhill.

  1. Drive with the brakes on all the way down the hill to keep me at a safe speed.
  2. Throw the truck into a lower gear.

Which is better for the vehicle?

The primary reason to use a lower gear is safety. When you’re riding your brakes for a long period of time, all that friction turns into heat, which can overheat your brakes and cause them to fail. And travelling down the mountain without brakes won’t be good for the vehicle.

What actually happens is that the brakes get red-hot, and that heats up the brake fluid. Once the brake fluid boils, it’s no longer able to transmit hydraulic pressure, and you can’t stop the car.

That kind of constant heat also increases the likelihood that your brake discs will warp and need to be replaced. And the truth is, putting the truck in a lower gear when travellDriving down from mountaining down a steep grade does no harm to anything else.

You’re just taking advantage of the natural compression in the engine (the pistons compressing air) and using the transmission to apply that natural engine braking to the wheels. The car will make more noise because the engine is revving faster. But it’s not hurting anything.

Occasional braking is fine. So ideally, you’ll find a gear where you’re moving fast enough to get home before the ballgame is over, but not gaining so much speed that you have to sit on the brakes constantly.

So try shifting one gear lower and see how much natural braking you get. If it’s not enough, drop down another gear. And if you get down to first gear and you’re still not going slowly enough, look for another job.
