Everything You Need To Know About Brake Pads
What is Brake Pad?
Brake pads are crucial parts of the car braking system. Each and every time you will press the brake pedal; this force would translate by way of a hydraulic system to the caliper. The brake pad would be pushed by this caliper onto the car’s brake rotors which are flat discs on the car wheels. Both the pressure as well as friction would work together as a team to slow down your vehicle or can also bring it to a complete pause.
Materials Of Brake Pad
Have a look at the materials of the brake pads:
- Non-metallic materials - These are composed from a combination of a lot of synthetic substances bonded into a composite, principally in the form of cellulose, aramid, PAN, as well as sintered glass.
- Semi-metallic materials - There are some synthetics which are mixed in different proportions of flaked metals. They are solid than other non-metallic pads, are more fade-resistant and at the same time last longer, but it would lead to the rise in wear to the rotor/drum which should be restored sooner.
- Fully metallic materials - These pads are generally utilized in the racing automobiles and are made up of sintered steel and there are no synthetic additives in it.
- Ceramic materials - These are made up of clay and porcelain bonded to copper flakes and filaments, and works as a great compromise between the durability of the metal pads, grip and fade resistance of the synthetic variety.
Types Of Brake Pads
There are four common types of brake pads in regular automobiles, so let’s have a look at them below:
- Semi-Metallic - Semi-metallic is the regular type of brake pad which is widely utilized in a lot of automobiles as it has long term durability and at the same time provides great heat transfer capability. It is composed of steel wire or wool, graphite or copper, and friction modifiers.
- Non-Asbestos Organic - This type of brake pad is generally composed of fibers, high-temperature resins, and filler materials. Now if we compare this type to the semi-metallic type, then they are much softer and create little noise, but at the same time degrade at a faster rate and produce more dust.
- Low-Metallic NAO - The low-metallic NAO are composed of organic materials with 10%-30% metal like steel or copper in the mix. They create more noise and brake dust, but at the same time their braking as well as heat transfer capabilities are superb.
- Ceramic - A little amount of metal can be found in this brake pad type. They are generally made up of ceramic fibers, bonding agents, and nonferrous filler materials.
Features Of Brake Pad
- Make sure that you choose materials from semi-metallic, rigid molded, or sintered friction pads for resistance to heat
- The pads should be chosen with thorough testing and quality assurance
- Go with performance look for the most reliable and well-tested pads for your application
- There should be friction for high heat dissipation select cutting-edge technology sintered pads
- There should be long Life OEM or reverse engineered replacement, you can always look at the replacement and ongoing maintenance costs
How Does A Brake Pad Works?
Brake pads are a major part of the car brake because it would contact and then apply pressure as well as friction to a vehicle's brake rotors which are flat, shiny discs which you can see behind the car wheels of some vehicles. The car would be stopped by the pressure and friction which is applied to the brake rotor. Now once the car wheels would stop turning, then the automobile would also stop moving. The major role of brake pads as braking components is very simple, the brake pads themselves are anything but because of how fast the car’s wheels would rotate and how much a typical automobile or truck weighs, the brake pads would undergo extreme stress every time you would slow down or even come to a pause.
Symptoms Of Bad Brake Pad
Here are a few symptoms which would be produced by the brake pads to alert the driver that there is a requirement of service. Let’s have a look at them below:
- Noisy brakes - Noisy brakes are the first and the foremost symptom of a defective brake pad. A lot of dust can be accumulated in the brake pads as they wear, and if it would be allowed to build excessively, then it might cause a lot of vibration as well as squealing when there would be an application of the pedal or let off.
- Pulsating pedal - One another common symptom of some failure in the brake pads is a pulsating brake pedal. The brake pads were worn out severely can cause the pedal to pulsate when there would be an application of the brakes.
- Poor brake response - Faulty brake pads can give rise to poor brake response. Now if the brake pads have an overheated a lot or might have been worn, then the brake pads won’t be able to slow down the vehicle properly as they used to do before.
Tools Needed For Brake Pad
There are a number of skilled auto mechanics who have a goal of opening their own car repair shop at some point in their career. But let’s face it; if you want to put up an efficient as well as profit making shop, then you might need much more than mechanical skills. There are a number of tools which you might need to perform the car repairs quickly as well as reliably. Auto repair equipment that you will need to repair your Brake Pad may include:
Top Brands For Brake Pad
When it comes to vehicle owner’s choice, the brands really matter a lot. You might pay a premium for a specific car part brand, over time, as it has created a perception of quality, stability as well as trust. There are some leading car parts brands which are more than just products or services as they give rise to memories and emotions related with the quality. So have a look at some of the top brands for Brake Pad.

Brake Pad Repair Cost
There are a lot of factors which should be considered when you are thinking of replacing Brake Pad. First you have to decide that if you require some related parts of Brake Pad or a whole Brake Pad. Then after that the next step is to decide what type of make as well as type of Brake Pad you are actually dealing with and then from where will you get a brand new one. Just keep in mind that a brand-new Brake Pad which would come from a warehouse would cost much more than the one you will get in a junkyard. After that the next point which should be considered is that from where you are going to get it replaced and how quickly it needs to be done. If you want to substitute the cushions, then it might cost $49 to $100 and a drum, rotor, and additionally caliper substitution might can get up into the few hundred depending upon the degree of the problem.
How To Change Brake Pad
First of all, the lug nuts should be loosened up. The automobile should be raised by utilizing a jack and it should be secured properly on the jack stands.
After that the lug nuts and wheels should be removed.
Then the caliper fasteners should be removed and then they should be set aside. The caliper should be pulled away from the pads and rotors.
The brake fluid reservoir cap should be removed and then its level should be checked. Now when you will compress the caliper pistons, then there would be a rise in the fluid level in the reservoir.
A caliper hanger or bungee cord should be utilized to secure the caliper so that it would be out of the way.
Use a caliper hanger or bungee cord to secure the caliper so that it's out of your way but not left hanging by the brake line.
The caliper bracket fasteners should be removed and then carefully set them aside. The bracket should be pulled off of the rotor with the pads attached. It is essential to note the orientation of the pads inside the bracket and then the pads should be removed.
If there is hardware and caliper grease in your new pads, then you must restore the hardware and then grease should be applied as per the instructions.
Then it is important to check the rotor as there is a need to replace the rotors periodically.
Then it should be reassembled in the reverse order by utilizing your new pads. Carefully torque all fasteners to spec, and then all the steps should be repeated on the other wheel.
The vehicle should be lowered down and then brakes should be pumped a few times. The recommended driving procedure should be followed to break in the new pads.
