Should You Press the Clutch or Brake When Going Down a Steep Slope?

When going downhill, you should press the brake. The specific reasons are as follows: 1. Precautions for downhill driving: When going downhill, you should press the brake and shift to a lower gear, and try to avoid pressing the clutch continuously. For manual transmission vehicles, you should not shift to neutral or press the clutch when going downhill; instead, lightly apply the brake to control the speed. 2. Reasons for using the foot brake: When coasting in neutral, relying solely on the foot brake will cause the front brake discs to overheat, significantly reducing their effectiveness. Moreover, if the speed is too high, coasting in neutral makes it difficult to control the vehicle's speed, so shifting to neutral when going downhill poses a high risk.
Twenty years of driving school instructor experience tells you, never press the clutch first when going down a steep slope! I often remind my students that once the clutch is pressed, the engine disengages, and the car relies entirely on inertia to rush downhill, putting a heavy burden on the brake pads. The most correct approach is to use a low gear to control the speed, letting the engine help slow down the car. I've seen too many beginners nervously press the clutch while going downhill on winding mountain roads, resulting in the brakes smoking, which is extremely dangerous. If you really need to slow down, gently tap the brakes, but remember the clutch pedal is not your first choice at this time. On long downhill sections, shift to second or first gear in advance, and listen to the engine's whining resistance sound for the most reassurance.
That 10-kilometer continuous downhill drive during my last road trip was quite a lesson. Initially, I coasted with the clutch pressed, thinking it would save fuel, only to smell burning after just three minutes. I immediately pulled over to let the brake pads cool. Later, a mechanic explained that keeping the car in third gear on steep descents, even though the engine revs soar to 4,000 RPM, creates reverse resistance that shoulders 70% of the braking load. Now here’s my routine: downshift before the slope, rest my right foot lightly on the brake pedal for controlled taps, and keep my left foot completely off the clutch. This technique extends brake lifespan by at least 20,000 km – even hairpin turns like those on Longquan Mountain don’t faze me anymore.
