Delving into M Carbon Ceramic Brakes: Advantages and Considerations

For those seeking the pinnacle of braking performance, particularly for track use, M Carbon Ceramic Brakes are now available for the first time on models like the new BMW M3 and BMW M4. These represent a significant step up from standard M compound brakes, offering distinct advantages alongside some crucial considerations.

M Performance Sport Brake Pads

Developed directly alongside the new carbon ceramic brakes, the ‘M Performance Sport Brake Pad’ is specifically designed for high-temperature applications, such as those encountered on a racetrack. The life expectancy of these pads is considerably longer when subjected to the extreme heat that typically occurs during track driving. While standard pads might exhibit a drop in friction coefficient at high temperatures – a phenomenon known as fading – the friction coefficient value of sport pads remains far more stable, providing consistent braking power when it's needed most.

It's important to understand that with sport pads, comfort factors are often secondary to raw performance. This means that considerable braking noise can be a fact of life for drivers who choose them, especially under certain driving conditions. Furthermore, sport pads are more expensive and exert considerably more force on the brake discs. Disc wear is several times higher than with standard brake pads. For this reason, BMW recommends that every time a set of sport pads is fitted, new discs also have to be installed. Consequently, sport pad kits are typically offered, comprising both the pads and the required brake discs.

The Importance of a Cooling-Down Lap

After a session of spirited driving or track activity, performing a cooling-down lap is absolutely critical for the longevity and integrity of your braking system. If you park your car while brake discs are still at temperatures of 500 degrees Celsius or more, the considerable heat will transfer throughout the entire brake system. This heat can be absorbed by the brake pads, and the transfer can progress through the back plate and damping plates of standard pads into the brake calipers. This intense heat can damage piston seals, dust shields, and even the surface coating of the brake calipers. Leaving brakes to cool in a stationary position under such extreme temperatures is extremely unfavourable.

By performing a cooling-down lap, the brake temperature generally falls to below 200 degrees Celsius. This controlled cooling allows the materials in the brake components to dissipate heat in an airflow, significantly reducing the risk of thermal damage. Such high temperatures typically do not occur during normal road use; they would require several successive braking manoeuvres from full speed to stationary to be reached.

Advantages of M Carbon Ceramic Brakes

M Carbon Ceramic Brakes offer a multitude of benefits, particularly for performance-oriented driving:

• Weight Reduction: The rotating masses in M carbon ceramic brakes are approximately 12.5 kg lighter compared with standard M compound brakes. This reduction in unsprung mass significantly improves handling, steering response, and overall vehicle agility.
• Enhanced Performance: These brakes are dimensioned to offer significantly more in terms of performance. Instead of 18-inch M compound brakes, M carbon ceramic systems typically feature larger 19-inch carbon ceramic brake discs. They deploy a six-piston caliper on the front axle and a four-piston fixed-caliper brake on the rear axle. The operational surfaces of the brake pads are appreciably higher, meaning the M carbon ceramic brake offers a considerable advantage in terms of sheer stopping power and stability, especially on the racetrack.
• Corrosion Resistance: A significant advantage is that the carbon ceramic disc is not susceptible to corrosion. Unlike conventional grey-cast iron constructions where rust films can form on the friction ring, especially with low mileage, long idle periods, or low usage, this does not occur with M carbon ceramic brakes. This eliminates the rubbing effect and compromised performance that can result from corroded brake discs.
• Reduced Wear: M carbon ceramic brakes are less subject to wear. The brake pads themselves wear more slowly, and under normal use, the carbon ceramic brake disc is designed to last as long as the car itself, with its silicon carbide friction coating being virtually non-wearing. However, it's important to note that on the racetrack, the brake discs may be subject to oxidative wear.

Detecting Oxidative Wear in Carbon Ceramic Discs

When carbon ceramic discs are repeatedly heated to temperatures of 600 degrees Celsius and over, the fibres within the brake disc can burn up. This means the disc does not become progressively thinner but rather lighter. To detect the level to which this may have occurred, three wear indicators per friction coating are applied to the disc, set apart at angles of 120 degrees. This allows a BMW dealer to recognise when discs have been subjected to high levels of oxidative wear. The service team can then weigh the brake disc; if it weighs less than the minimum permitted weight, the disc must be replaced.

Disadvantages of M Carbon Ceramic Brakes

Despite their superior performance, M Carbon Ceramic Brakes do come with certain drawbacks:

• Production Complexity: The manufacturing process is far more complex and time-consuming. One step involves siliconising the friction ring for a period of 24 hours at 1,300 degrees Celsius. The carbon fibre-reinforced silicon-carbide brake disc has a total throughput time of several weeks with the manufacturer before it is ready.
• Higher Purchase Price: This complex production process explains why the purchase price of the M carbon ceramic brake is significantly higher than conventional systems. However, this higher initial cost is partly balanced out by their lower wear rate under normal use.
• Special Characteristics: This system does have a number of special operational characteristics you should be aware of. Brake discs and brake pads in M carbon ceramic brakes only achieve a favourable wear and contact pattern after around 1,000 km of use. Furthermore, due to their material-specific properties, increased operational noise may be experienced when braking, particularly in wet conditions or just before the vehicle comes to a halt. It is crucial to understand that this noise does not affect the brakes’ performance, operational safety, or stability.

Choosing Your Brake System: A Comparative Overview

When it comes to high-performance BMWs, the choice of brake system significantly impacts driving dynamics, cost, and maintenance. Here's a comparison to help you understand the differences between standard genuine pads, M Performance Sport pads, and the advanced M Carbon Ceramic system.

Frequently Asked Questions (FAQs)

Are genuine BMW brake pads worth the investment?

Absolutely. While they may carry a higher initial cost than some aftermarket options, genuine BMW brake pads provide guaranteed fitment, optimal performance, and superior longevity. They are developed alongside the vehicle, ensuring all braking system components work in harmony, which is paramount for both safety and maintaining the vehicle's intended driving dynamics.

Can I use aftermarket brake pads on my BMW M?

While aftermarket options exist, genuine BMW brake pads offer specific advantages that aftermarket brands may not replicate. These include precise engineering for your specific model, access to the latest material revisions, and a guaranteed level of performance and durability that aligns with BMW's rigorous standards. For high-performance M models, sticking with genuine parts is generally recommended to ensure the best possible braking capability and safety.

How often should I replace my BMW M brake pads?

The lifespan of brake pads varies significantly based on driving style, the type of brake system (standard, sport, or carbon ceramic), and whether the vehicle is primarily used on the street or for track driving. Generally, standard pads on a road car might last tens of thousands of miles. Sport pads used on a track will wear much faster, as will the discs they act upon. Carbon ceramic pads tend to last longer, and the discs can last the lifetime of the car under normal road use, though they are subject to oxidative wear during intense track sessions.

What is brake fading?

Brake fading refers to the reduction in stopping power that occurs when brake components, particularly the pads and discs, become excessively hot. This heat can reduce the friction coefficient of the pad material, leading to a noticeable decrease in braking effectiveness. M Performance Sport pads and M Carbon Ceramic brakes are designed to mitigate fading during high-temperature, high-performance driving.

Why is a cooling-down lap important after track driving?

A cooling-down lap allows the extremely hot brake components to cool gradually in an airflow. This prevents thermal shock and excessive heat transfer to other parts of the braking system, such as caliper seals and dust shields, which can be damaged by prolonged exposure to very high temperatures while stationary. It helps preserve the integrity and longevity of your braking system.

Do carbon ceramic brakes make noise?

Yes, M Carbon Ceramic Brakes can produce increased operational noise, particularly when cold, wet, or when braking at very low speeds just before coming to a halt. This is a characteristic of the material composition and does not indicate a fault or affect the brakes' performance, operational safety, or stability.

How do I know if my carbon ceramic brake discs need replacing?

Unlike conventional discs that wear thin, carbon ceramic discs can experience oxidative wear on the track, leading to a reduction in weight. BMW service centres use three wear indicators on the disc and a weight test to determine if a carbon ceramic disc has reached its minimum permitted weight due to oxidative wear, indicating it needs replacement.
