Wheel brake assembly

Types of wheel brake assembly

A brake wheel assembly is a crucial component in the safety and performance of vehicles. It comes in different types, each designed to meet specific braking needs. Here are the most common types:

• Disc brakes

  Disc brakes are the most common type of brake in modern vehicles. They consist of a brake rotor (disc) that is attached to the wheel. During braking, brake pads, which are housed in the caliper, clamp on the rotor to create friction and slow down the vehicle. Disc brakes offer excellent stopping power and are less prone to brake fade. They are ideal for cars that drive at high speeds and those that are heavy. There are different types of disc brakes, including:

  • Slotted disc brakes

    In slotted disc brakes, the rotors have slots on the surface. The slots offer a better bite and help in reducing brake fade. These rotors are mostly used in performance cars.

  • Drilled disc brakes

    Just like slotted disc brakes, drilled disc brakes have holes on the surface of the rotor. The holes help in removing brake dust and improving airflow.

  • Composite disc brakes

    These are specialized disc brakes that are made using different materials. The most common material is carbon, which offers high performance and durability.

• Drum brakes

  Drum brakes are another common type of brake wheel brake assembly. Instead of a disc, they use a brake drum that is similar to a rotor. Inside the drum, brake shoes push out and touch the drum to create friction and stop the vehicle. Drum brakes are more affordable and are mostly found in older car models. They are also used in the rear wheels of most modern vehicles. However, they are gradually being replaced by disc brakes.

• Anti-lock braking system (ABS)

  ABS is not a brake type but rather a brake wheel assembly feature. It prevents the wheels from locking up during hard braking. It does this by modulating the brake pressure. Vehicles that have high performance and are expensive come with ABS as a standard feature. Some mid-range vehicles also have ABS, especially in higher trims.

• Electric brakes

  Electric brakes use electric motors instead of conventional brake pedals to apply the brakes. They offer consistent braking force and precise control. Electric brakes are mostly used in hybrid and electric vehicles. They are also becoming popular in high-performance vehicles.

Specifications and maintenance of wheel brake assembly

Specifications of wheel brake assemblies vary for each car model and type. Generally, the specifications include the brake type, rotor size, brake caliper size, brake pad material, brake booster, ABS, ESP, and parking brake details. Below are some of the specifications of the wheel brake assembly.

• Brake type

  The brake type is a significant specification to consider when purchasing a brake wheel. It includes disc brakes and drum brakes. Some vehicles come with a combination of the two brake types.

• Rotor size

  Every vehicle has a rotor size measurement in millimeters. The rotor size contributes to the braking power of the brake system. Larger rotors offer a more powerful and efficient braking system.

• Brake caliper size

  The brake caliper works hand in hand with the brake rotor to form a brake system. The brake caliper houses the brake pads and pistons. The brake caliper size affects the braking force.

• Brake pad material

  There are different kinds of materials used to make brake pads. Each material has its advantages and disadvantages. For example, ceramic brake pads are quiet and produce little dust. While metallic brake pads have high friction and are long-lasting.

• Brake booster

  The brake booster specification is important even though it is found in the brake line assembly and not in the wheel. The brake booster uses engine vacuum pressure to amplify the force applied on the brake pedal. It makes the braking process easy and efficient.

• Anti-lock Brake System (ABS)

  The anti-lock brake system is an important feature in modern vehicles. ABS prevents the wheel from locking up during emergency braking. It increases the stability and safety of the vehicle during braking.

• Electronic Stability Program (ESP)

  Some vehicles with advanced technology have an electronic stability program. The electronic stability program helps in vehicle stabilization during braking, especially in slippery roads.

• Parking brake details

  Normally, the parking brake is a lever that is manually operated. In modern vehicles like those with a hybrid brake system, the parking brake can be electronically controlled.

Watch out for the following maintenance tips for a wheel brake assembly to last and work well.

• Vehicle owners should regularly inspect their brake systems. The inspection helps to know if there are worn-out parts in the brake system. Replace worn-out parts to avoid further damage to the wheel brake assembly.
• Brake pads and brake shoes should be changed once worn out. It is advisable to change brake pads and shoes at the same time to maintain balance in the brake system.
• Brake fluid level should be checked and topped up if necessary. Change the brake fluid after two years or when the fluid gets contaminated.
• Remove brake dust from the wheel brake assembly using a damp cloth. Users can also use a specialized brake cleaner to get rid of brake dust.
• Do not ride the brakes for long. This practice can easily damage the rotor by overheating it.

How to choose wheel brake assemblies

There are numerous options for brake wheel cylinders to choose from, and it can be challenging to find the perfect fit for any vehicle. Below are some important factors to consider when shopping for brake parts:

• Vehicle Compatibility

  It is important to consider the type and model of the vehicle before purchasing a brake wheel assembly. This is because not all vehicles are compatible with every brake part. Check the manufacturer's manual to confirm the type of brake assembly recommended for the vehicle.

• Driving Habits

  Consider the driving habits before choosing a brake wheel cylinder. For instance, if the vehicle is used for heavy hauling or frequent towing, it is advisable to go for a larger and more durable brake wheel assembly. On the other hand, a standard-size brake assembly will be appropriate for a vehicle with normal driving conditions.

• Budget

  Brake parts come in different prices depending on the size, brand, and type. It is important to set a budget before going to shop for brake assemblies. However, it is advisable not to compromise on quality. Look for a premium-quality brake wheel brake assembly at an affordable price.

• Quality and Brand

  There are numerous brands and manufacturers of brake wheel brake assemblies in the market today. It is advisable to choose a reputable brand that offers quality products. Don't go for cheap products from unknown brands. They might be affordable, but they are of low quality and might not serve the purpose.

• Installation

  Consider how the brake assembly will be installed. Some models come with easy-to-follow instructions for DIY installation, while others require a professional to install them. If planning to install the brake parts by oneself, go for models that are easy to install.
