 A guide to Brembo braking systems in the premier class and their use for the second time on the Misano World Circuit Marco Simoncelli

​​​​​​​​​

Seven days after the thrilling San Marino and Riviera of Rimini Grand Prix, the first after lock-down to be open to the public, the Misano World Circuit Marco Simoncelli hosts the first ever Emilia Romagna and Riviera of Rimini Grand Prix. The track is the same as the one used last week and so is the direction and travel and time. 


According to the Brembo technicians who work closely with all the MotoGP World Championship riders, the Misano World Circuit Marco Simoncelli is a moderately demanding circuit for brakes. On a scale of 1 to 5, it earned a 3 on the difficulty index. ​


 
 




Brembo calipers for MotoGP​​​​


The Brembo 4-piston monobloc calipers for MotoGP are made from a single block of billet machined aluminum. Compared to casting, billet machining allows for the use of materials with better mechanical characteristics and greater resistance to high temperatures. 


The shape of the caliper body is conceived to optimize the mass/stiffness ratio using the topological optimizer, a computer program derived from 40 years of victories in 500/MotoGP. The calipers used from this year onward have a higher number of cooling fins and are lighter than in the previous year. The surface finish has a nickel filler.


 




Brake use during the Emilia Romagna MotoGP Grand Prix​


From the start to the checkered flag, each rider will use the brakes over 320 times, exerting a total force on the brake lever of at least 1.2 tonnes, the highest in the whole championship: on the Red Bull Ring, the force was 9.5 quintals, at Brno 8 quintals and at Jerez 9.7 quintals. 


Three times each lap, the MotoGP riders experience a deceleration of 1.5 G, all in the first 8 bends, whereas on all the other bends, the value ranges from 0.8 G to 1.1 G. On half of the braking sections, the system is in use for less than 2.5 seconds which brings the discs and pads back to normal temperature much more quickly. ​

 

 

The braking section on the first bend of the Emilia Romagna and Riviera of Rimini Grand Prix ​ ​


Of the 12 braking sections at the Misano World Circuit Marco Simoncelli, 3 are classified as demanding on the brakes, 3 are of medium difficulty and the remaining 6 are not very demanding. 


The braking on the first bend is the second hardest on the track: the motorcycles go from 272 km/h (169 mph) to 116 km/h (72 mph) when using the brakes for 4 seconds. As they cover a distance of 201 meters (659 feet), the riders exert 5.3 kg (11.7 lbs) pressure on the brake lever and experience deceleration of 1.5 G. The braking system pressure reaches 11.4 bar. ​​ ​
