Form the majority of brake make up situations.
Bearings are part of axle not brakes.
Other parts will be hydraulics, fluids, cables. Pins. Bolts etc
Disc(rotor) brakes are easiest normally to maintain. With pads easily changed by most people able to do competent DIY work.
Drum brakes use. Shoes not pads...these tend to last longer.
Technically arguments for both types hold merit. Rotor type now becoming the main type almost everywhere though.
Disc brake components:
Calipers, rotors, master cylinder, servo/booster, lines, hoses, reservoir, sometimes bearings (some systems are called hub type rotors, they incorporate the brakes and bearings. Some have axle bearings, which are not technically part of the brake system)
Drum Brakes (dumb brakes):
Drum brakes are mostly the same parts, except drums instead of rotors, shoes instead of pads, wheels cylinders instead of calipers, all held together with springs. There are 2 main types of drum brake systems, single servo and duo servo.
Disc brakes are safer, quieter, longer lasting, and easier to maintain. They also self adjust, which single servo drum brakes do not. It is much easier to change out disc brakes than drum brakes as well.
Disc brakes also work better in ABS and Traction control systems.
Think of a disc brake where the caliper and pads are basically a vice. They grab the disc. Drums you push the shoes outward, into the drum, centrifugal force is your brake action.
2 Part Question
1: Type of Brakes.
*Disc Brakes
*Drum Brakes
*Air Brakes - for large trucks
1-1 Brakes can also be classified as Hydraulic (uses fluid) and as Air brakes (uses air pressure)
2: Parts of each type
You can literally break down each brake system and have a list of hundred of parts down to nuts, bolts, springs, shims, etc. Most were already answered by others.
Look up each type and you'll find more details about them.
Either use the force of pressure to force a piece of soft metal into harder metal. The resulting friction is what slows you down.
But contrary to what has been said above, Drum brakes last about 3 times longer than disk. That said, they tend to rust and seize onto hubs, provide less braking power given their weight, and add rotating mass to your wheels. This rotating mass lowers both your acceleration and powertrain efficiency. It also increases your unsprung weight of your hub, which aids in dampening but overall harms suspension performance.
Two more types of braking can be added to your list.
With hybrid and full electric vehicles entering the market, electromagnetic / regenerative braking (Depending on how you think of it). This is when the drive motors that provide the power to get the vehicle moving are cut off from their power. Rather than being disconnected from the wheels, the copper coils inside the motor spin within a magnetic field. This creates an opposing magnetic field and current, both providing a force opposing the movement of the vehicle and recharging the batteries in the vehicle.
Second is hydraulic/hydrostatic vehicles. Not as common in the US market, but in china are becoming larger and are used among heavy equipment and busses. It functions similar to the electromagnetic braking above, except with a hydraulic motor in place of an electric one.
Also: hydraulic fluid and tubing.
No there are different parts to both drum and disk because the braking action is different for both.
Drum brakes are called that because everything happens inside a large round bowl, or drum. Inside the drum is a pair of shoes, which when the brakes are applied, are squeezed against the inside of the drum, and that's how the brakes slow the car down. The drum must be extremely smooth inside, so the shoes can be applied safely on the surface of the inside of the drum.
But the safest kind of brake is the disk, which is called that because the brake surface is a giant disk which rotates in the same direction as the wheel it is on. The disk is also called a rotor. The caliper is a metal piece that fits over the disk.
Take an open hand, and close it with thumb and rest of fingers making a groove, and that's kinda how a caliper fits over a disk or rotor.
When you apply disk brakes, there is a little piston on the caliper, which is then applied to the rotor or disk, and that is what slows the car down.
Disc brakes work much better than drum brakes because they apply much better pressure than drum brakes. But even tho' they are much better, they cost much more, and so that's why some cars have only disc on front wheels and drums on rear wheels, because most of the braking actiion is on front wheels, so you have the better or disc brakes on the front.
Bearings are not part of the brakes, they are little tiny steel balls inside the axle that lets the wheel turn easily.
hello,
what are the different parts of a car brake system -
as far as i know - they are
rotor
brake pads
bearings
caliper -
and what also.
does the above parts appy for both disc and drum type brakes..which type of brake is easy to maintain and what is the difference between two type of brake and which one gives longer life and safety
