Are you a truck driver or a repair store for commercial vihecle truck trailers? Do you need to change your brake shoes? Do you know which is the best quality brake shoe? How to choose a high quality brake shoes?
Goto ALLMAX to know more.
We POWERTECH are a professional brake shoes manufacturer and supplier in China for commercial vehicles and auto cars with more than 20 years experience. Today, let me tell you how to identify which is a high quality brake shoe.
A brake shoe is the part of a braking system which carries the brake lining in the drum brakes used on automobiles, commercial vehicles or the brake block in train brakes and bicycle brakes. A device that is put on a track to slow down railroad cars is also called brake shoes.
The quality of brake shoes is defined by material, manufacturing process, process quality control and quality standard which brake shoes manufacturers are according to.
If you are a consumer or a driver, it&#;s really difficult to know the manufacturing process.However we can judge the quality through the following aspects
The below post is for consumers only, if you are a professional brake shoes buyer, importer or distributor, please refer to the below post.
Steel Material is most important for brake shoes. Some brake shoes factories use low grade steel to get low prices. Frankly it&#;s not possible for consumers to test the material. However, we can consider the following aspects.
Generally, thestell thickness tolerance is +/-0.2mm, if the thickness tolerance exceeds +/-0.2mm, then we can suspect that the steel is not purchased from a famous steel manufacturer.
Brake shoes welding is very important for quality. Welding depth and welding strength is very important. However, as a consumer or driver, we only can identify the welding quality from the appearance.
point welding, segment welding, full welding.
We recommend segment welding or full welding brake shoes.
In welding, appearance is a key indicator of quality (via workmanship), with the width, shape and uniformity of the weld crown bead, presence and uniformity of the root bead, and weld profile width-to-depth ratio and shape being especially telling indicators.
weld width. weld defects, such as crack, porosity, undercut&#;.
brake shoe welding defectsIf the dimension is correct, it will cause brake lining uneven wear and brake jump. Damage the brake hub and brake pads, causing driving safety. How to check the dimension of the brake shoe?
First, we need to get a standard brake lining to check if the brake shoes and brake lining fit well. The gap between the brake shoe and brake lining should be less than 0.8mm before riveting, and It&#;s better to be less than 0.5mm after riveting.
It&#;s really difficult for a consumer to measure the position dimension. However we can judge it in another way.
There are several surface treatments, such as painting, powder coated, electrophoretic coating. powder coated and electrophoretic coating are our first choice.
Moreover, you need to check if it is rust at the edge of the brake shoe and weld edge. If the surface treatment is not good, then it&#;s easy to rust from the edge of the weld joint and brake shoes.

Brakes play an important role in stopping a vehicle, even if it is at maximum speed. When brakes are pressed, many brake parts work together in a blink of an eye. The brake shoes or brake pads hold the brake drum or rotor which in turn decelerates the wheels and stops the vehicle. Brake shoes are similar to brake pads but are used in drum brake systems. These are commonly used as the parking brake even in many modern vehicles. This brake shoe guide will help you understand and buy the correct brake shoes for your vehicle.

What Are Brake Shoes and What Do They Do?A brake shoe is a curved piece of metal component that has a friction material known as a brake shoe liner fitted on it. At the time of braking, these brake shoe liners get pressed against the rotating drum to stop the vehicle. Because of rubbing against the wheel drum these liners wear out, which has to be replaced after a certain period.

Brake shoes are found in old and even in modern cars. Brake shoes are the first braking parts introduced in vehicles. In old vehicles, all wheels have brake shoes, but in many modern cars they are fitted only on the rear side and brake pads are fitted on the front side. The brake shoe not only works as the main brake but also serves the purpose of the vehicle&#;s emergency brakes (handbrake).
Brake shoes are part of a drum brake system, which is an older type of braking system and has become less common on modern vehicles. They are not the same thing as brake pads, which are part of a disc brake system. While brake pads and brake shoes perform similar functions, they are not the same thing. Brake pads are squeezed together by a caliper against a rotor disc, generating the friction needed to stop the car.

What Are The Type Of Brake Shoes?The brake system and its components keep us safe on the road. So, it is important to know more about them. The brake shoes vary, depending on vehicle type and size of the brake drum, but the function is the same to stop the car
1. Leading / Trailing Shoe Type Drum Brake
This type has a single wheel cylinder and a pair of brake shoes known as the leading shoe and the trailing shoe. Leading brake shoe is a term referring to the shoe that moves in the direction of rotation when it is being pressed against the brake drum. The other shoe is called the trailing shoe. The brake shoe is pressed in the same direction as the rotation of the brake drums, and this rotation helps to press the brake shoes against the brake drum with higher pressure for better braking force. This is called the servo effect or the self-boosting effect which provides the powerful braking forces of the drum brakes. These brake shoes work in a way that they both become either the trailing shoe or leading shoe, depending on whether the vehicle is moving backward or forward.
2. Twin Leading Shoe Type Drum Brake
This type of drum brake has a pair of wheel cylinders fitted in opposite directions, and a pair of brake shoes are fitted on them. Each wheel cylinder presses one shoe towards the rotating brake drum so that both shoes act as leading ones when the vehicle moves forward, giving the best braking force.
The duo servo type has a structure where a pair of brake shoes is fitted. It is called the primary shoe and secondary shoe. These brake shoes are connected via an adjuster. Powerful pressure from the servo effect or self-boosting effect from the primary shoe is sent to the connected secondary shoe, thus creating a very large braking force.
Every brake shoe which is made has a curved metal plate, mostly made of steel. These plates have different sizes of holes for the fitment of anchor pins and return springs. But the friction material that is fitted on the plate, is fitted on the brake shoe in two types.
1. Riveting Type Brake Shoes
This is the oldest method of fitting a brake liner on the brake shoe. For this, depending on the size of the brake shoe, six to eight holes are drilled on the area where the liner is to be fitted. The same is done with the brake liner which is then placed on the brake shoe. After matching both of them, metal rivets are fitted, securing the liner with the brake shoe. You can even change your riveted brake shoes with bonded brake shoes.
2. Bonded Type Brake Shoes
The bonded type brake shoes are mostly used in two-wheelers but are also found in cars and trucks. In this type, the glue is applied on the brake liner&#;s inner side and on the outer side of the brake shoe. Both parts are then placed on each other and are then pressed with the help of a pressing machine. You have an option to buy riveted brake shoes or bonded brake shoes.
Every vehicle has a different size of brake shoes depending on its make and model. Brake shoes can be found in the front and the rear or can be fitted only in the vehicle&#;s rear. The front and the rear brake shoes slightly differ from one another. The main difference is, the rear brake also contains hardware for the parking brake due to which the rear brake shoe design can vary, making it slightly different from the front brake shoe assembly. For this reason, always be sure which side of the brake shoe is required.
When this type of brake shoe wears, there is an excessive gap between the brake drum and the brake shoe, due to which the brake pedal travels slightly more than usual for better braking. To remove this excess gap, the brake backplate has a snail-type cam or an adjuster gear that is connected to the brake shoe. When the cam or the adjuster gear is rotated, the brake shoe is pushed towards the brake drum, hence removing the excess gap from the brake pedal. This is an important maintenance requirement in manually adjusted brake drum designs.
Today this type of brake shoe is found in almost all cars. Automatically adjusted brake shoes have small threaded self-adjusting components. When there is an excessive gap between the brake drum and the brake shoe, the adjusting component pushes the threaded screw, which then pushes the brake shoe towards the brake drum, thus maintaining the gap.

What Are The Factors I Should Consider Before Buying A New Brake Shoe Set?Depending on the brake drum size, there are different sizes of brake shoes, because of which they differ from one another, this difference may even exist between different models of a car. For this, it is necessary to choose proper brake shoes specific to your vehicle&#;s make and model. Some brake shoes are vehicle-specific, so finding one that is meant for your vehicle is necessary for a precise fit and function.
There are constant advancements in brake shoe materials development. These advancements result in less operating cost and maintenance, which gives better functionality and overall consumer satisfaction. When it comes to brakes, choosing the right materials is essential. Brake shoes are made from copper, steel, iron, and several other alloys with durable and heat-resistant materials. Brake shoes made from ceramic components are popular because of their durability, energy absorption, and decreased noise while braking. The brake shoes can even include materials like semi-metallic compounds, ceramics, mineral fibers, plastics, aramid fibers, cellulose, and even chopped fiberglass.
There are many companies in the market, and each company has unique design and manufacturing processes that determine their reliability and performance. For this reason, it&#;s tough to select brake shoes that are best for your vehicles. OEM brake shoes are engineered for maximum strength in your specific vehicle. This guide also has some aftermarket brands like Raybestos, Wagner, Agna, and many more, which are mentioned, that match the fit and performance of the OEM parts, and some even exceed that providing more features and benefits.
Once brake shoes are replaced, it becomes necessary to check their function for any abnormal sound while braking. It is also necessary to check the wheel cylinder for any brake oil leakages. The brakes should be tested at different speeds to ensure proper stopping. The emergency brake or also known as the hand brake should be checked and set accordingly.
Due to the brake shoe location, they are always exposed to water and weather conditions which can make them rusty. To avoid the rust problem, many manufacturers apply safety coatings on brake shoes to prevent rust and extend the component&#;s life. While buying brake shoes you should look for such rust preventive coatings that ensure the brake shoes will last a long time and provide a good service life.

How Much Should I Pay For New Brake Shoes?Depending on the vehicle you drive, the new brake shoes will cost you around $20 to $30 for a single wheel. While the labor cost for the same is only about $8 to $12. Depending on the make and model of the car, the brake shoes can be found on all four wheels or on the rear wheels only. All brake shoes are individual components but work together to stop the car. If you change all the brake shoes, it will multiply the amount depending on the number of brake shoes. Prices ranges are different and also vary from one brand to the other. If you have the proper tools and knowledge, you can change the brake shoes yourself and save a lot of the labor.

When Should I Change My Brake Shoes?While brake shoes may not require service frequently, they will not last forever. A person will apply brake multiple times during driving. If you hear any noise coming from the wheels while braking, it can be worn brake shoes. But if you ignore it and continue on your driving, the expense could be more. Because when the brake liners are totally worn out, the rivets on the brake shoe can cause damage to the brake drum and in some conditions, there is no option but to replace the brake drum with a new one. Brake shoes must be checked and should be replaced in order to avoid issues with the braking system. The brake shoes are designed to last around 40,000 to 45,000 kilometers, but there are chances that replacement may come early. Few of the many reasons that can lead to increased wear of brake shoes like bad road conditions, poor driving habits, and weather.
