While driving a vehicle stopping distance is calculated on the basis of driver’s thinking of distance, meaning that distance travelled by vehicle before the driver reacts to a hazard on the road and the braking distance, which is how long the vehicle takes to stop once the driver applies the brakes.
The overall stopping distance depends on thinking and the braking distance, and the braking distance further depends on various circumstances. It is these circumstances which affect the overall stopping distance:
- Thinking distance: Thinking distance depends on the driver and also the speed at which the vehicle is travelling. This can be increased by the following factors:
- Drivers tiredness and alertness
- The driver taking drink or drug (legal or illegal)
- Age of the driver-underaged and overaged driver may also have an increased thinking distance
- Lack of concentration of the driver-using mobile phone while driving
- The bad vision of the driver also leads to decrease reaction distance
- Braking Distance on Web-Dry Surface: Besides the speed at which the vehicle is travelling, braking distance gets affected and can increase by the below-mentioned points:
- The Vehicle’s weight.
- Brakes condition, in case of worn out discs/or pads longer time, is taken by vehicle to stop on wet weather.
- Wet or icy roads increases the braking distance.
- The condition of the road surface- On well-maintained roads with smooth surface less braking distance is there, whereas gravel, dirt and mud on the road will increase braking distance.
Further, the braking depends on the efficiency of your vehicle’s brakes. The following vehicle-related aspects are also to be considered when calculating the braking time and distance.
Braking with locked wheels
There is very less variability in stopping distance when braking with locked wheels, but however, on the wet roads, there is a much more dramatic reduction in friction which can result in your vehicle ploughing ahead on entry to a corner. A sudden locking of wheels gives you feeling of your having a vehicle with ASB system, as this type of braking with locked wheels is not recommended with ordinary braking systems.
Tires pressures and grip
With lower pressure in tires increases the size of the contact patch. So letting out some air from tires (of course as per the manufacturer’s guidelines) will help to have more grip in wet conditions. But all this can be done up to a certain point.
The depth of tread in tire and braking distance: Research has confirmed that tires with more tread depth have a greater ability to stop the vehicle at a small distance in the wet and icy roads. Extra 8 meters is required if the tread depth is 25% or less to stop the vehicle and 13 meters if the tread depth is less than 10%. Brakes work better if they are 100% working and if their slight variation in the efficiency level sudden braking leads to the brake failure all of a sudden in the emergency. So brakes should be always kept in the perfect working condition always.

One of the most forgotten Brake components is caliper. Since every person driving the vehicle is not an expert and ignore the brake caliper service. Did you know that as per the recommendations of expert, it is necessary to service brake caliper after every two years or 40,000 Kms? Brake Caliper servicing is not a typical brake service but is somewhat different from it.
What are Brake calipers, and why they are important?
Brake calipers house the brake pads and, using brackets, pistons, and calipers side pins when help push the pads into the brake rotors when you apply the brake.
With the passage of time, the side pins that referred above use their lubrication and don’t slide the calipers well. With lack of lubrication, the following things start to happen;
- That Brake’s don’t contact the rotor correctly; brake pads wear unevenly.
- The side pin can get stuck. This causes the brake pad to continually contact the rotor and leading to heat buildup, resulting in faster wear and tear of brake pads
- Brake stopping power of your vehicle may become weak due to the brake pads not hitting the full surface of the brake rotor.
All this results that we are not fully getting used to the brake pads and it is just like burning or throwing dollars away.
How Brake Caliper service is undertaken
Before servicing the Brake caliper, the pressure in the anti-lock brake accumulator should be released by pumping the brake pedal till it gets hard or as specified in the service manual. After this bleeder screw should be loosened to allow old fluid to be flushed out of caliper bore. Any clogged bleeder screw must be removed for cleaning or replacement. It is cheaper to replacer sized caliper screw.
After reliving the caliper of the pressure, sized pistons be removed with caution by easing the piston from the bore by gently applying air pressure to the brake hose port while backing out the C-clamp screw. Since piston surface seals the brake caliper, if the piston is pitted or scored, it is better to replace it. Once the piston is installed, remove the caliper guide pins and lubricate them with caliper grease and apply thread-locking compound when the caliper bracket bolts are installed. It is better to always install new caliper hardware on the caliper bracket to prevent pad rattle and dampen pad squeal.
When the caliper is correctly serviced slide it smoothly on its guide pin or guide surfaces and should allow the rotor to turn freely when the brake pedal pressure is released. In case of caliper won’t release, the interior rubber of the brake hose might be peeling and blocking the fluid return to the master cylinder reservoir. Any misadjustment in master cylinder push rod or brake pedal height may be correctly adjusted, which is preventing master cylinder from releasing the fluid pressure from the caliper.
