Braking Distance 101

blog-braking101

The braking distance is a concept we drivers know in a practical sense or at least we think we do. But there is science that we can use to really measure how long our cars take to stop after we slam the brakes. In theory, the braking distance or stopping distance (d) in metres equals to initial velocity square (v0^2) divided by coefficient of friction (μ) and gravitational pull of the earth (g). In a mathematical equation it would look like this:

We know nobody likes maths, so we took a shot at making it more relatable and you are welcome to confirm our findings:
⦁ A car travelling at 50km/h (a speed that nobody in Dubai ever drives at) will take a distance of 12.27 metres to come to a complete halt. If you are working out the numbers yourself, remember to convert the speed into metres per second(m/s) simply by dividing it by 3.6. The friction between rubber and cement is 0.8 and gravitational pull as we all know is 9.81 m/s^2.
⦁ Now let us imagine driving on Sheikh Zayed Road, travelling at 110km/h. How long does it take for our car to stop then? Well the answer is 49.15 metres! Which is close to half the length of a football field!
Now, just so you know, we haven’t taken in to account a number of factors that play a part such as, reaction time of the driver, condition of the road, the tyres and the brakes. The latter two cannot be included in the equation but the first two complicate the equation anyway. Want to take a look at the mathematical representation? Here it is:

To conclude, here is the lowdown:
⦁ It will take way longer for you to stop than you think.
⦁ Even if it is somebody else’s fault, you risk your safety and the safety of the passengers and the car when you do not maintain a safe distance from the car in front.
⦁ Tyre and brake maintenance of your car is absolutely critical.
So we invite you to drop in at Splendour Auto Care Center and let us take a look your tyres and brakes. We have a fully equipped facility with specialist technicians and helpful service advisors, eager to ensure your safety.

The Hummer Project

1We at Splendour Auto Care Center are pleased to report that we have successfully brought Hummer H1 back into its best shape. It arrived at our facility in an immobile state with numerous mechanical issues, which were rectified by our mechanical specialist Noor Yousouf, over the course of six days. From brake oil leak to the four-wheel transmission malfunction, he was able to fix all faults without any major replacements, retaining the original capability, as intended by Hummer.

2Splendour Auto Care Center is a fully equipped facility with specialist technicians that delivers premium quality service at a reasonable price. Built on a unique concept to bridge the gap between expensive agencies and local garages, we strive to deliver what the market has been missing. Watch this space to find out more about our projects.

Why is tire care important?

tires-blog-post

Well that’s very basic and logical but let’s list out the key factors here for clarity before we begin:

  • They are the only four contact points between your car and surface. That means your acceleration, turning capability and braking depends on them.
  • Carry the entire weight of the car.
  • Have to overcome all obstacles on road and for some of you, even off-road.

Okay now that we are on the same page as to why tires deserve our attention, let’s look at basic signs that you can check yourself to see if your tires need replacement:

  1. Tread grooves disperse water from beneath your tires. Shallow tread will lead to a lack of water displacement (known as aquaplaning) and thereby resulting in reduced traction. Pay attention to this one as this is possibly the most important.
  2. Check your tire pressure at least once a month to see if there is any major change in it. If your tires regularly lose pressure, something is wrong.
  3. Uneven tire surface is another crucial indicator. For obvious reasons, tire manufacturers make tire surface even, so if you feel there is unusual wobbling in the steering wheel or a decrease in ride quality, examine the tires.

So what are few simple steps you may take to extend the life of your tires?

  • Firstly, stop hitting anything with the side of your tire, be cautious of it when you drive.
  • If you own soft tires like Michelin, avoid driving on rough patches like gravel.
  • Pay attention to your wheel alignment and tire rotation.
  • Don’t overinflate or underinflate your tires, stick to the guidelines on tire pressure.
