Get Info Get Info. The foot brake holds the rotor between brake pads, and friction is used as a braking force. Increasing the proportion of using engine brakes allows you to reduce the frequency of foot brake use, and you can make the pads and rotors last longer.

When stepping on the foot brake, the brake lamp lights up, and you can notify the following vehicle that you are decelerating. However, the brake light does not illuminate when engine braking.

If you use the engine brakes to decelerate suddenly, be aware that there is a possibility that you will be bumped into by the following car, so be careful. If you drop from top gear to low gear suddenly, just because you want a large braking force, the difference between the tyre and the engine speed will increase too much, the drive wheels will lock and slip, which is very dangerous.

In addition, it puts a strain on the engine and gears and can lead to failure of these components. When changing down gears, be sure to make it one gear at a time.

This all depends on how close to the red line the RPM is, and how long it stays there. Drive for too long with a high RPM, and the engine could overheat, placing strain on the radiator and cooling system. Another thing to remember when engine braking is the risk to the transmission system. Jump from a high to low gear quickly, and you can place unnecessary strain on the gears and clutch plate, potentially leaving you with a repair bill much higher than the cost of a new pair of brake pads.

To reduce the strain on the transmission, rev-match when downshifting by using the throttle to increase the engine speed, then slowly and smoothly let your foot off the clutch. This means you can enter a lower gear without an uncomfortable jolt, and with minimal wear to the transmission system. In normal driving conditions, using the footbrake is almost always the safest and fastest way to slow the car down.

You can engine brake in normal driving conditions, but this is purely used as a way to prevent brake wear — not as a safety measure. There are some instances, however, when engine braking is a safer and more efficient option than using the footbrake, and will help to slow the car down without the risk of skidding or overheating the brake pads to the point where they stop working.

The thing is, using the footbrake will actually make matters worse when roads are slippery, as the car will enter a slide more easily if the wheels lock-up or are slowed suddenly. Maintenance February 9, Tweets by VATireandAuto. What can we help you with? Shop Tires Top brands.
