How Car Braking System Works, And Why It Is Important To Maintain It Regularly

At Battmobile UAE, we deal with car brake system failure grievances daily. To witness your car’s brake system succumb to downtime is a nightmare that you want to never have to deal with. But cars are mechanical devices, and they are likely to run into problems from time to time. While we would recommend that you reach out to Battmobile in case of any untoward automotive events, we also believe that car drivers must be duly educated and well-informed about their cars – inside out. In this blog post, we are giving you a rundown related to car brake systems – how they work, their types, and how you can keep them in good order.

First and fore most. The braking system is the most critical safety aspect of an automobile. It can slow or stop the automobile in that critical split second, preventing a major accident. A brake system is composed of several components that work simultaneously to slow the automobile down and keep it safe. A braking system is intended to slow and stop the vehicle’s motion. To do this, multiple components of the braking system must transform the kinetic energy of the vehicle into heat.

Now, let us simplify and explain how car brakes do what they do.

Working of the Brakes

  • Most modern-day vehicles are equipped with brakes on all four wheels. These wheels perform their tasks based on a Hydraulic system. The brakes placed in the front are more important than the ones placed at the back. This is because the braking system moves the weight of the vehicle to the front of the vehicle. Ideally, Disc brakes are used in front and Drum brakes are used at the back as Disc brakes are comparatively much more efficient. Some of the low-cost, high-performance vehicles might also use Disc brakes at all four wheels.
  • When the brake pedal is pressed, the vehicle transmits force directly from the driver’s sneaker to the brakes by way of fluid. But obviously, such a small force cannot stop the vehicle entirely. Hence, the brakes need a force greater than that which could be applied with one’s foot. As a result, the vehicle must increase the severity of the foot, either by multiplying the hydraulic force or by creating traction with an angular momentum.Let us now focus on the types of car brakes that are installed in cars.

Hydraulic Brakes

  • This mechanism works by connecting cylinders via brake pipes, which receive fluids via the hydraulic brake circuit. Most contemporary automobiles have two hydraulic circuits as well as two master cylinders. The purpose of having two sets is in any case if the hydraulic system fails, the other can be used as a backup. In some cases, the circuit will handle the front brakes while the other works the back brakes.
  • The hydraulic brake system uses brake fluid to transfer pressure from the brake pedal to the pads or shoe. When you press down on the brake pedal, brake fluid distributes this force to the brake pads.This transfer of pressure is dependable, safe, and consistent as liquids used are not compressible.
  • When a driver applies pressure at the brake pedal, the mechanical force (driver stepping on the pedal) is changed to hydraulic pressure which is transmitted through the liquid to the respective wheel cylinder and changed back to mechanical force.

Disc and Drum Brakes

  • These brake systems depend upon friction to reduce the speed of the vehicle. The applied force is translated to hydraulic pressure that moves through hydraulic fluid lines directly to the wheels, causing the brake shoe to press against the drum wheel.
  • If the braking system is a disc system, the pressure travels down the fluid lines to the wheels, where it causes the disc pads to press on the brake rotors.The ensuing fiction reduces wheel rotation about the level of force applied to the pedal. As mentioned above, Disc brakes are the more efficient of the two.

Anti-Lock Braking System

  • It is an automated system that stops the wheels from completely stopping their rotation and hence prevents skidding of the vehicle. ABS is extremely useful on both dry and slick surfaces. This mechanism is meant to eliminate the need for the driver to pump the brakes. Rather, the driver merely needs to press the brakes with considerable force, leave the foot on the pedal and let the system work its magic.
  • Lastly, now we give you an overview of some of the tips and tricks you can turn to when it comes to car brakes system maintenance.
  • Car brakes have a shelf life. Your breaks will eventually suffer wear and tear and would require maintenance or sometimes even a replacement. Do not let your brakes to such a degree where the replacement of the part is inevitable. It is because the replacement charges are very expensive and also are prone to accidents. Hence regular maintenance of the brakes is very important. Following are the methods by which you can regularly maintain the brakes of your vehicle.


  • The touch points between the braking system and your wheels are your brake pads and rotors. Both of these components endure plenty of wear and tear over extended use and hence will require frequent replacement. It is, therefore, important to routinely check the quality and depth of your pads from time to time.


  • Your vehicle’s brake fluid is extremely important since it’s the contact fluid between you and your braking system. Unfortunately, brake fluid attracts moisture, which can corrode the metal components of your braking system, lowering the boiling temperatures of the fluid and diminishing its efficacy when the brakes are engaged.Brake fluid needs replacing every 20,000 miles. Milky or cloudy quality brake fluid indicates it is time to have a flush.


  • Replacing your braking parts after a certain period is highly advisable as, after such extensive use, most of the components suffer from wear and tear. Also, it often proves to be a good opportunity to upgrade your vehicle to better parts and higher performance. For example, you could replace your stock discs with slotted discs that are more heat resistant.
  • The best way to ensure that the performance of your brakes is to look after them. It’s important to avoid situations like a heavily loaded vehicle or extremely wet weather since they significantly affect your braking performance. Avoiding such circumstances and regularly maintaining your braking systems will also help keep your braking system working better for longer, reducing the likelihood of brake failure at a time of need.
