Topic 8 of 14 · Braking
Smooth control, braking and what to do in a skid
Why braking and steering compete for the same grip, how to use a lower gear on a descent, and how to respond when a skid starts.
By the end of this lesson
- Brake and steer in the correct sequence rather than at the same time
- Use engine braking on a descent to keep the brakes cool
- Respond to a skid without making it worse
Grip is a budget
Each tyre has a finite amount of grip, and everything you ask of the car spends some of it: accelerating, braking, cornering.
Ask for all of it in one direction and it usually works. Ask for it in two directions at once — braking hard while turning — and you can run out.
That gives you the basic rule of smooth driving:
Brake in a straight line. Steer with the brakes off. Accelerate gently as the car straightens.
Slow in, gentle out. It is not a racing technique, it is what makes a car predictable in the wet.
Down a hill, down a gear
On a long descent, holding the brakes on continuously heats them until they fade — and a soft pedal at the bottom of a hill is a genuinely frightening thing.
Instead, select a lower gear before you start down. Engine braking holds the speed, and the brakes are only needed occasionally, in short applications, which keeps them cool.
The same applies uphill in reverse: change down before the engine starts labouring, so you keep some acceleration in reserve.
Coasting
Coasting means travelling with the clutch down or in neutral. It removes engine braking, reduces your control, and on a descent lets the car build speed with only the brakes to stop it.
Keep the car in gear until just before you stop.
Skids
A skid means the tyres have lost grip, and the cause is nearly always the driver: braking, steering or accelerating too harshly for the conditions.
If the wheels lock under braking, release the brake so they can turn and grip again, then reapply more gently and steer where you want to go.
If the rear slides out on a bend, ease off the accelerator smoothly and steer gently in the direction the rear is sliding — rear going right, steer right. Sudden movements caused it and will not fix it.
With ABS, brake firmly and keep the pressure on. The pedal will judder; that is the system working. ABS helps you keep steering while braking hard, but it does not create grip that is not there, and on loose or icy surfaces it may not shorten the stopping distance at all.
Aquaplaning — light, vague steering in standing water — needs the opposite of instinct: ease off, keep the wheel still, and do not brake until the tyres bite again.
Why it matters
Almost all of this comes down to being smoother and earlier than feels necessary. A car being driven gently has grip in reserve. A car being driven at the limit of its grip has nothing left for the thing you have not seen yet.
The three things to remember
- Tyres have a finite amount of grip. Braking and steering at once splits it between two jobs.
- Down a hill, down a gear. Continuous braking overheats the brakes until they fade.
- In a skid, ease off and steer gently in the direction the rear is sliding. Sudden inputs caused it and will not cure it.
⚠ The common mistake
Coasting with the clutch down or in neutral, which removes engine braking and leaves the brakes doing all the work at the moment you most need options.
On the road
A downhill left-hander in the wet. Brake in a straight line before the bend and the car is settled through it. Brake mid-corner and you are asking four small contact patches to do two things at once.

Answer these without scrolling back up. Retrieving something from memory is what makes it stick — rereading feels productive but does far less.
