Your Guide to Brake Shoes Replacement For your Vehicle

  • Date 13/04/2015

Vehicle brakes are the most important safety tools for any vehicle. Most people only look into how fast a vehicle can go, but it is even more important to consider how quickly and effectively a vehicle can be brought to a complete stop. A good set of brakes on a vehicle can draw a thin line between life and death in most cases.

This is why it is important to keep a look out for the wearing and tearing of your brakes and invest in good spares when opting for a brake shoes replacement at regularly. These below are a guide to help you understand the importance of choosing the right kinds of suit your vehicle and ensure that the vehicle has optimal stopping power at all times.

Drum vs. Disc
Disc brakes and drum brakes are the most commonly used braking systems in modern vehicles. A disc brake has two disc pads on each sides of a brake rotor. When the vehicle brakes are applied, an action caliper forces these discs to squeeze against the rotor, which in turn slows down the wheel, eventually stopping it. These are usually found in the front wheels of modern vehicles.

The drum brakes, however, have a set of brake shoes that are set up in the inside of a brake rotor. When brakes are applied, these beak shoes expand and push against the wall of the rotor in order to bring the vehicle to a complete halt. Drums breaks is an older technology and are traditionally used in the rear wheels vehicles. In both of the cases, the braking mechanisms use friction to stop the vehicle. Thus, brake shoes replacement should be done on a regular basis as it wear off, or at regular intervals as recommended by the vehicle manufacturer.

Disc brakes are considered to be safer and more efficient than their drum counter parts because discs breaks can dissipate heat much more efficiently when compared to drum brakes. Discs breaks are also generally more consistent in their breaking operation. These properties make discs one of the most desired braking systems for vehicle manufacturers

Types of brake shoes
There are four types of car brake shoes in the market today, and the classification is based on their compositional materials.
Semi Metallic Brake shoes: Like it name suggests, these types of made of a combination of metallic and organic materials. These pads are highly durable, and are among the most commonly used brake shoes. However, they do wear out the rotors faster than the other under extreme braking conditions since the material does not dissipate heat efficiently.

Non Asbestos Organic brake pads: Commonly known as NAO, these are made of organic materials like glass, rubber, fiber or Kevlar. They are quite soft and do not make much noise as the metallic brake shoes type. However, they do wear out quicker and tend to create a lot of brake dust.

Low Metallic NAO: These are Organic that are combined with trace amounts of metal such as copper or steel in order to improve braking efficiency and heat dissipation.

Ceramic Brake shoes: Ceramic are high quality products that are made of ceramic fibers infused in filler materials. They do not wear out the rotors as fast as others do. However, they are quite expensive and are used primarily on higher end vehicles.

Generally, smaller or slower road cars can use semi metallic shoes with no adverse consequences. However, if you need to replace brake shoes of bigger vehicles such as trucks and SUVs, or faster cars, you might have to invest in more expensive low metallic or ceramic.
