Disc Brakes
To stop or slow the wheels, disc brake rotors rotate with the wheels, and the brake pads attached to the brake calipers grip the rotors. When the brake pads rub against the rotors, friction is created, converting kinetic energy into thermal energy.
This thermal energy produces heat, but the main components are exposed to the atmosphere. This diffuses effectively, preventing brake fade. Disc brakes are resistant to water fade, which occurs when water on the brakes significantly reduces braking force.
Disc brakes are most commonly found on passenger cars but are slowly making their way into the commercial vehicle segment, where drum brakes were previously preferred due to their longer life. Customers are increasingly demanding higher quality and longer shelf life.
Disc brakes are classified into two types.
There are pistons on both sides of the rotor in an “opposed piston type disc brake,” but only one in a “floating type disc brake.” Floating caliper disc brakes are another name for sliding pin disc brakes.
Construction of disc brakes
Reducing speed and stopping the vehicle is achieved by rotating the brake rotor (disc) with the wheel and holding it by brake pads (friction material) installed in the caliper from both sides with the pressure of the pistons. (pressure mechanism).
Automobile brakes
Brakes are installed on each of the four wheels of a car. Depending on the use or characteristics of the vehicle, disc brakes or drum brakes are used.
Systems of disc braking
A brake is a device that slows down or stops the movement of a body. By acting on rotating mechanical elements, most brakes absorb kinetic energy mechanically, hydrodynamically, or electrically.
The most common type of brake is a mechanical brake, which uses mechanical friction between a rotating metal drum or disc and a stationary friction element that comes into contact with it by mechanical, hydraulic, or pneumatic means to dissipate kinetic energy in the form of heat.
Bands or shoes (blocks with a concave surface) can be used as friction elements for drum brakes, while pads or rings can be used as friction elements for disc brakes. Friction materials can be organic, metallic, or ceramic, with molded asbestos being the most common.
Trains disc braking systems
Continuous train braking systems fall into two types: vacuum, which is still widely used on railways in developing countries, and compressed air, whose inherent efficiency has been improved by modern electrical or electronic control systems.
If a train becomes uncoupled while it is in motion, breaking the controls connection across the train automatically applies the brakes to both parts of the train. Modern passenger cars and some freight vehicles use disc brakes instead of track shoes.
To prevent wheels from spinning during hard braking, devices are installed on the wheelsets of cars traveling at speeds of 100 mph (160 km/h) or more. To supplement the disc braking of the wheelsets, electromagnetic track brakes are fitted to European automobile trucks designed for speeds of 200 km (125 miles) or more, as well as Japanese Shinkansen trains.
When the bar magnets are lowered into contact with the rails, frictional resistance is created, causing them to slow down when activated at the beginning of deceleration from a high speed.
Eddy current track brakes are used in place of electromagnetic track brakes on some Shinkansen trains.
The eddy current brake is more powerful because it does not make contact with the rail (and is therefore not subject to frictional wear), but it creates strong electromagnetic fields that require enhanced immunization of the signaling circuit. Also, where trains with this equipment are used frequently, eddy current braking has the potential to overheat the rails, causing them to warp.
How disc brakes work
The brake booster (servo system) amplifies the force, and the master cylinder converts it into hydraulic pressure when the driver presses the brake pedal (oil pressure). Tubes filled with brake oil transmit pressure to the wheel brakes (brake fluid).
The supplied pressure pushes the brake pistons at all four wheels. The pistons press the brake pads, which are made of friction material, against the brake rotors, which rotate with the wheels. Both sides of the rotors are held by the pads, causing the wheels to slow down and the vehicle to slow down and stop.

- Brake fluid can be drawn out with a turkey baster.
- Plastic ties, bungee cords, or a piece of string are all good options.
Comparison of brake pad replacement prices
Brake pad
Brake pads is a component of disc brakes that minimize friction between the rotor and the caliper by inserting themselves between the two metals. Brake pads wear out over time due to friction and need to be replaced.
Best brake pads prices in Pakistan
In Pakistan, the price of brake pads ranges from PKR 985 to PKR 42,500.
| Brake Pads Price (Min) | PKR 985 |
| Brake Pads Price (Max) | PKR 42,500 |
Best rotor prices in Pakistan
Each rotor costs between $30 and $75. Higher quality rotors like Duralast Gold are more expensive as they feature a coated top and rim and are designed to outperform your car’s original equipment. Changing rotors and pads at a shop can cost anywhere from $150 to $200 per axle.
Best calipers prices in Pakistan
For passenger cars, friction-ready brake caliper can be found for under $100. For larger vehicles, it can cost several hundred dollars. However, if you want a loaded brake caliper with brake pads already installed, expect to pay $100-$500 for a replacement caliper.
Is it better to replace the brake pads and brake rotors at the same time?
If the car is relatively new and the brake discs still have a lot of life, there is no need to replace the brake discs. If the discs are similarly worn or badly scratched, they should be replaced immediately.
Look at the braking surface of the discs. At the edges of the braking surfaces, there are ridges. Below is a basic instance.
Only the points circled in RED indicate that the brake pad is in contact with the braking surface of the brake disc. Braking power is obviously reduced, and may even cause brake noise if the brakes are in this condition.
The brake pad and brake disc generate braking force. True braking potential cannot be achieved if one of the two is not in good working order.
Brake discs that needs replacement.
Brake disc with surface cracks.
Driving with worn brake discs is risky!
Have you ever thought: “The brake discs do not need to be replaced because they are metal; only the brake pads need to be replaced”. “I don’t drive on the race track and I drive safely on the street, therefore I don’t need it” or “I don’t drive on the race track and I don’t need it”.
Have you checked your brake discs recently?
People think it’s time to replace the record when the surface appearance changes to that of an LP record or when a crack appears. When the outer part (rim) of the brake disc began to wear gently, it was time to replace it.
What is braking?
When you step on the brake pedal, the brake pads and discs collide, causing friction.
The car can safely slow down by converting frictional energy into thermal energy.
Braking works this way. The ‘frictional heat’ generated throughout the process is crucial.
Disc/brake pad relationship
There is a limit to the amount of heat a brake disc or pad can hold.
If the heat capacity of a new disc or pad is “100”, when the disc or pad wears out, the heat capacity will drop to “90”, “80”, “70”, and so on.
Heat not stored by the brake rotor or pad is transferred to the caliper or brake fluid, causing a variety of heat damage.
.
The following are some examples of common heat damage.
- Brake caliper rigidity decreases
- Early loss of the disc or pad
- Disk is distorted, cracked, and has a worn step.
- Vapor lock in the brake fluid and fluid leaking from the screw
- Bending the brake pad backplate separates the friction substance (backing plate)
- Constant confirmation of disc/pad wear status is most crucial to reduce heat damage to a minimum.
- In addition, we sell effective brake temperature indicator stickers that detect heat damage.
When should brake discs be replaced?
- When either side of the braking surface is damaged more than 1mm on the front disc. When either side of the braking surface is worn by more than 0.5mm or 0.75mm on the rear disc.
- The wear limit value (Minimum Thickness) is stamped on each disc as “MIN TH OO” (Note that wear limits vary by part number, so be careful).
- The front of our SD drive features a slot that has been cut by approximately 0.75mm.
- As a result, when the slot groove disappears, it’s time to replace it.

Common Questions About discs brake
Q How many km should brake discs last?
On average, brake pads need to be replaced after 75,000 kilometers of driving. Some brake pads, on the other hand, need to be replaced after 25,000 kilometers, while others can last for 40,000. Consult your car’s manual for a more precise number for your vehicle’s unique requirements.
Q What is the minimum brake disc thickness?
The minimum thickness of the brake disc is 37 mm if continuous cracks are not observed. Replacement of brake discs should be done in pairs. When new brake discs are installed, the brake pads must also be replaced. If this advice is not followed, the braking performance of the vehicle may be seriously affected.
Q How do you know your brake disc size?
This is the diameter of the brake disc. The number of studs in the wheel is related to the number of holes. If the wheel has four bolts, brake discs with four holes are required. Pitch Circle – The theoretical circle determined by the location of the bolts is known as the pitch circle or pitch circle.
