Definition;- A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a plate that creates friction. The disc brake is a wheel obstacle that slows the rotation of the wheel by the friction caused by pushing brake pads against a brake disc with a set of calipers. This action slows the rotation of a shaft, such mechanical disc brakes as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed.
Hydraulically actuated brakes are the most commonly used form of brake for motor vehicles, but the principles of a plate brake apply to almost any rotating shaft. The abs wheel brake is that slows the rotation of the wheel by the friction caused by pushing brake pads against a brake disc with a set of calipers.
DISC BRAKE WORKING PRINCIPLE
The plate brake system is widely used on front wheels in mid-range two-wheeler such as – commuter & sports bikes. The Disc check system is used on the front wheels of most hatchback cars, entry-level sedans & MUVs; whereas, it is also widely used on both front & rear wheels of high-end cars and SUVs in combination with hydraulic / vacuum brake actuating and abs systems.
ANTI BRAKE LOCK SYSTEM
An anti–lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface.
Disc brake got its name from the circular-shaped plate or disc or rotor; onto which the disc brake parts are mounted. A conventional abs Disc Brake system consists of a brake disc, two friction pads, and brake caliper. In the Disc restraint system; the friction pads apply grip on the external surface of the disc to perform braking.
TYPES OF DISC BRAKE SYSTEM
In the single-piston design such as in two-wheelers, the brake pads are actuated by a single-piston, which is attached to the brake caliper. When you press the brake lever, the brake oil pushes the piston causing the brake pads to contact and rub against the record. The friction between the brake pads and the disc causes the disc to stop rotating, thereby the wheel to stop. When you release the brake lever, the brake pads retract to their original position. This causes a gap between them and the disc and to again spin it freely.
The twin-piston design such as in cars is almost identical to single piston one, except for the pistons which are two in numbers. In this system, the twin pistons push the brake pads to apply the brake. The brake pads fit on the caliper which holds the brake system parts together. When the driver presses the brake pedal, the oil in the brake master cylinder multiplies the hydraulic force sent to the calipers; causing its piston to contract. The pistons, in turn, cause the brake pads to contact and rub against the disc. The friction between the brake pads and the disc causes it to stop rotating, thereby the wheel to stop.
TWIN CALIPER BRAKE;-
The third type twin caliper system; actuated by two calipers that work on the same principle of that of the single caliper brake system. In this design, there are two calipers instead of one. However, high-speed luxury cars more commonly employ this type of system. This system provides more effective braking. and, what are the advantages of dual-pivot caliper brakes?

VENTILATED DISC BRAKE;-
Modern vehicles come with ventilated discs. When you apply brakes, it converts the kinetic energy of the vehicle to heat due to the friction between the brake pads and the disc. Ventilated discs have passages or an air vent that helps pass air through the disc. Thus, it provides cooling & prevents brake fading.
ADVANTAGES OF HYDRAULIC BRAKE
- No adjustment required. So, no maintenance.
- Better stopping performance.
- Can check wear without dismantling the unit?
- Fade-free braking in all conditions. So, no fading of brakes.
- Easy & quick to replacement of pads compared to Drum brakes.
DISADVANTAGES OF DISC BRAKE
- High braking force needed compared to Drum brake.
- Low life of brake pads compared to brake shoes.
- Need separate hand-brake mechanism when fitted to rear wheels.
The performance review and the analysis of brake designs allowed us to develop the original disc brake mechanism with self-booting. The braking system is responsible for bringing a vehicle to a complete halt. the traditional disc and drum brakes have now been replaced by the anti-lock braking system. the advent of the Traction Control System and Stability Control System has provided better control over the braking of a vehicle. with the traffic norms getting strength by the day anti-lock braking system would one day become mandatory on all vehicles.
