Brake disc

Brake disc

A crucial element of the braking system of your two-wheeled vehicle or quad, the brake disc must be in perfect working order to ensure your safety in all circumstances. Understanding its role, knowing how to identify signs of wear and choosing the right model for your vehicle are all essential aspects to master. As a leader in the sale of spare parts for motorcycles, scooters, mopeds, quads and bicycles, we will guide you in the world of brake discs.

Understanding the role of the disk

To choose the right brake disc, you must understand its role and importance in your vehicle's braking system.

It is a metal component of your vehicle's braking system. Mounted on the wheel hub, it is on it that the brake pads rub when you apply the brake. It is this friction that helps slow and stop your vehicle. Due to the heat generated par this friction, brake discs must be made from materials capable of withstanding high temperatures.

Its importance in the braking system

The brake disc is one of the essential elements of the braking system. A worn, warped or poor quality disc can significantly reduce the effectiveness of your braking, with potentially serious consequences for your safety. It is therefore essential to regularly check the condition of your brake discs and replace them at the first signs of wear.

The different types of this braking element

There are several types of discs on the market. Each has its own characteristics and advantages. Here is an overview of the most common models.

The perforated or grooved model

As their name suggests, they have perforations or grooves on the friction surface. These particularities make it possible to improve the evacuation of water, dust and gases generated par friction of the brake pads, ensuring better braking performance in wet or dusty conditions. It is therefore an excellent choice for off-road or sporty driving.

The floating model

Designed for high-performance vehicles, the floating disc is made up of two parts: the hub, attached to the wheel, and the braking track, on which the pads rub. This allows the disc to expand freely with changes in temperature, improving its longevity and resistance to warping.

The ventilated petal model

With their particular petal-shaped design, these discs offer optimized cooling thanks to better air circulation. This extends the life of the disc by reducing its heating during intensive braking.

Common problems related to this item

Like any component of your vehicle, the brake disc is not immune to problems. Consider the following points to see if they are affected.

Striped model

Over time and wear of the brake pads, your disc can become scratched. In such a case, the friction surface will be less effective, thus increasing the braking distance.

Worn model

Prolonged and intensive use can wear out the disc. If its thickness becomes less than the specified wear limits par the manufacturer, it is recommended to replace it.

Veiled model

A shock, heating up too quickly or too tight a fixation can warp your disc. This can cause vibration and reduced braking effectiveness. If there is any veiling, it must be replaced.

Signs of wear and replacement

Knowing how to detect disc wear and knowing when and how to replace it are essential elements for your driving safety.

Raydamaged, warped, cracked or blued, it must be replaced.

It is generally accepted that the limit of use of a disc is 60 km. Remember to monitor their condition each time you replace the brake pads.

How to detect wear?

The first sign of disc wear is often a drop in braking system performance. In addition, abnormal noises (whistling, squealing) when braking may indicate wear or warping of the disc. Finally, vibrations at the brake pedal can be a sign of a warped brake disc.

When to replace this element?

There is no specific lifespan for a brake disc, itar it depends on many factors such as your driving style, road conditions, the type of disc you have, etc. However, it must be replaced when it is worn beyond the specified limit par the manufacturer, when it is scratched or warped.

In principle, it is recommended to change your discs every 4 or 5 sets of pads.

Choosing the right model for your vehicle

Choosing a brake disc should not be made lightly. Several criteria must be taken into account to make the right choice.

Selection criteria

The first selection criterion is of course the compatibility of the disc with your vehicle. You will also need to take into account your driving style and the type of roads you ride on. Finally, price is of course an important criterion not to be neglected.

The diameter of the disc must be taken into consideration. It is important to choose the same diameter as the original disc; in fact, the manufacturer will have selected it according to the power and weight of the vehicle.

The thickness of the disc will be the same as the original or previous disc.

The number of fixing holes remains a point to consider so that your disc is well fixed.

Choice based on vehicle type

Some brake discs will be more suitable for certain categories of vehicles. Par For example, if you own a sport bike, a floating brake rotor will probably be the best option for you. If you have a quad for off-road use, a perforated or grooved disc will suit you best.

The cost of a brake disc

The cost of this brake component depends on many factors, such as its type, brand, and quality.

Average cost and factors influencing price

On average, the cost of a disc for a two-wheeler or quad is between 30 and 150 euros. Higher-end drives, such as floating models, may cost more. Likewise, brake rotors from some well-known brands may be more expensive.

Brake pad cost

Remember that when replacing your brake disc, it is recommended to also change your brake pads. The cost of these ranges between 15 and 60 euros on average.
