What would you do if the brakes of the car completely fail while driving?
Here Are Some Important Tips To Do If Your Brakes Fails:-
Use Your Lower Gears:
Lower gears act as an engine braking. Engine braking will reduce your speed up to 5-20km/h but no more - your car will continue to creep forward.
Note: Don't put your car into reverse while you are going forwards because you risk causing a huge amount of damage to your gearbox.
Use The Handbrake:
If your car is at high speed do not pull the handbrake. Because it may overheat the engine. Wait until engine braking has dropped if your vehicle's speed is below 20km/h, then pull the handbrake gradually.
Give Clear Warning Lights To Other Drivers:
You can use a horn to warn other drivers. If other drivers know that you are facing difficulties. They will give you the way out of the traffic.
Get Out Of The Way Of Other Traffic:
As I have previously given signals or indicators to other people that you are facing difficulties. Other people will give you the way out to the traffic area. This will good for you and others as well.
Things Not To Do If Your Brakes Fail:
-Don't put your gearbox into neutral or you'll have no engine braking.
-Don't put your gearbox into reverse
-Don't stop the engine - you'll lose your power steering
So the regular auto brake maintenance is very important.
