Brembo Brings High Performance Brakes to Brutal Donington Park
Brembo tackles the extreme braking demands of Donington Park with specialized steel discs while preparing for a carboceramic future.

The Five Star Severity Challenge
Brembo engineers graded Donington Park a perfect five for braking severity. Riders hit the brakes seven times during every single lap. They spent 24 seconds of each lap hard on the lever. The track gave the machinery no time to cool down.
Turn 1 required massive effort from the racers. Speed dropped from 261 km/h to 96 km/h in just 3,8 seconds. The deceleration took 174 meters to complete. Riders pulled a heavy 6 kg of force at the lever.

The Secret of Rotor Thickness
Brembo supplied 13 of the 14 teams with specialized steel discs. The rotors came in two diameters of 336mm and 338.5mm. Engineers chose from various thicknesses ranging from 6.2mm to 7.4mm. Thickness acted as a vital heat sink against brake fade.
Thinner rotors saved rotating and unsprung weight for the motorcycles. This helped the bikes turn much faster in tight corners. Teams matched the brake thickness to the engine braking characteristics. Every choice depended on the specific motorcycle layout.
The Evolution of Brake Technology
The race caliper used a monobloc aluminum unit machined from a single billet. Four 34mm pistons provided the clamping force. Distinctive cooling fins added 30% more surface area to shed heat. This elite racing DNA now exists on premium production street bikes.
Brembo warned riders against using the Z04 race pads on public roads. The race pads had poor bite when cold and wore out too quickly. Street riders needed softer compounds like the SA and LA series. These pads worked well in the rain and cold weather.
Brembo will become the exclusive braking supplier for the grid next season. They will introduce new Hyction carboceramic discs to production based racing. Will this exotic technology improve everyday road bikes? The final chapters of the steel disc era are quietly closing.
Frequently Asked Questions
Why is Donington Park hard on brakes?
The track has seven braking zones per lap with multiple heavy stops stacked together. Riders spend 24 seconds per lap braking, leaving no time for the system to cool down.
Why does rotor thickness matter in racing?
Thicker rotors provide more thermal mass to absorb heat and prevent brake fade. Thinner rotors reduce weight to help the motorcycle turn and change direction faster.
Can I use Brembo Z04 race pads on the street?
Brembo advises against street use because the Z04 pads have poor cold bite. They wear out quickly and require extreme racing heat to function safely.
