Braking a car......?

Question

Whenever I brake I always brake smoothly until the car finally comes to a stop it always jolts forward suddenly, why is this?

I brake slowly and steadily and then when I am coming to a stop I press the clutch down and then slightly pull back on the brake (to ease it).

What am I doing wrong?

Answer 1

You need to depress the clutch before the engine speed drops to it's idling speed (check the rev counter with the engine running & the car stopped). You need to press the clutch in as the engine drops below about 1,000 rpm - perhaps higher; If when you do thus, the revs jump, then the engine management is applying the accelerator to prevent the engine from stalling, and you need to disengage the clutch sooner.

Practice braking by slowing down & pressing the clutch & keeping it down, but as the car comes to a standstill, release pressure on the brake to come to a smoother halt. Doing it this way isolates whether it's your braking or clutch control that makes the car stop abruptly.

Answer 2

U have manual or automatic, if manual then first press coupling pedal and then dont bother about gear and break slowly.

If you think its car fault not yours try breaking with gear off.

Answer 3

here's my advice for making the clutch and throwout bearing last longer.

When slowing down to a stop, leave it in gear, when you slow down to about 15mph, tap the gas and pull it into neutral, no clutch.

Now just use the brake to stop.

Answer 4

If you know that you are coming to a complete stop as soon as you start to apply the brakes, push in the clutch, this will teach you better braking technique and also save you a bit of gas.  Try this and you should not have the problem of the final jolt forward.

Answer 5

What kind of car is it? A lot of German cars, BMW, Mercedes, Volkswagen, use what's called Brake Assist. There is actually a computer using the ABS mechanicals to help you brake harder in an emergency. There is a slightly disconnected feeling from the brakes that performance drivers tend to notice and complain about. I have currently have 3 cars that exhibit exactly the symptoms you mention. Even if you lift ever so slightly just as the car comes to a stop, you may notice the brakes don't lighten up in the least. It's not broken, it's just something the manufacturers have to refine in the future. It must be harder than it sounds because they've been this way for a while. If you have a Japanese or American car doing this, I can't explain it unless they use a form of brake assist as well.
