How to Replace or Repair the Brakes

Brake Systems

We understand that there are many do-it-yourselfers out there who can perform even complex auto repairs on their own. We hope that our articles will help DIYers complete their installations without a hitch. We aim to educate car owners on the functionality, repair, and maintenance of car parts. Even if you are not a regular do-it-yourselfer, understanding various car parts and their various aspects can help you explain the exact problem to the mechanic and get it fixed. Above all, as a car owner, having automotive knowledge can be useful in emergency situations.

How to Replace or Repair the Brakes

When the brake pedal is pressed in an automobile, the vehicle comes to a complete stop. It also reduces the speed of a vehicle. Hydraulic braking systems are the most common type of braking system found in automobiles. This is more of a synopsis of how the various components of a braking system work.

The reservoir, master cylinder, caliper, and pads are the basic components of a disc brake system. The reservoir is where the incompressible brake fluid is stored. When you press the brake pedal, fluid flows from the reservoir to the master cylinder and is compressed. The fluid then flows to the slave cylinder in the brake caliper via the brake lines. The caliper presses the brake pads against the brake rotor, bringing the vehicle’s wheels to a halt.


Some vehicles have two reservoirs in the master cylinder, so if one fails, the other can take over. Vehicle brake systems are classified into two types: disc brakes and drum brakes. Except for the difference in their components and the direction in which each applies force, the drum brake system, and disc brake system function similarly. In a drum brake system, the brake shoes replace the pads, and the wheel cylinders replace the calipers. Because of their simplicity, low cost, and long service intervals, most drum brakes are now only found on the rear wheels of budget-conscious small cars, with disc brakes on the front wheels.

Disc brake systems, on the other hand, are much stronger and can apply much more force to bring the vehicle to a stop much faster. Many brake rotors have internal vanes to help dissipate the tremendous heat generated during the braking process. Furthermore, variations on the standard “smooth” type of brake rotor can provide better heat dissipation and braking performance.


Slotted brake rotors have channels or “slots” machined into their friction surface that allow gas and brake dust to escape, resulting in better pad-rotor contact. These slots also help the rotor’s face cool more evenly, lowering the likelihood of brake rotor warpage due to overheating. Cross-drilled brake rotors, on the other hand, have holes in their faces that directly connect the rotor’s friction surface to the internal cooling vanes, lowering brake temperatures and providing a path for outgassing. Some rotors even combine cross-drilled and slotted brake rotor designs to provide the best of both worlds: excellent initial bite in wet and dry conditions, superior cooling capacity, reduced brake fade, and stunning looks.


Power boosters, which are located between the brake pedal and the master cylinder, are included in brake systems to improve braking power even further. These boosters work by using vacuum to multiply the force applied to the brake pedal. This significantly reduces the amount of effort required to press the brake pedal. ABS is incorporated into all modern braking technology to provide better traction and control over the vehicle while driving on slippery road conditions. There are also air brake systems, which are commonly found in buses and trains.

Automobiles have hand brakes, which are also known as parking brakes, in addition to disc and drum brakes. When the hydraulic system fails completely, these brakes are used. If you do not ignore the symptoms of defects in various parts of the brake system, a hydraulic system will rarely become completely inoperable. Brake fluid can frequently leak from brake components, resulting in decreased braking performance. Reduced braking pressure, stuck pedals, and increased stopping distance are all common symptoms of a failing braking system.
