The special stages are quite wavy, but they are primarily characterised by impressive descents where the brakes are crucial. On the Ibarilla special stage, the drivers go from 2,599 to 2,065 metres in approximately twenty kilometres.



The Rally Italy also puts the braking systems to the test because it takes place on unpaved roads endowed with a great deal of grip and they constantly change direction, which means the brakes are continuously used to correct the path of the cars. As if that isn't enough, there are also many ups and downs that demand the use of the brakes to stay on the road.



The Rally Argentina is also present in the category of rallies on unpaved roads that are very demanding on the braking systems. The problem in this race is that the cars have to cross fords which may cause thermal shock.



This increases the risk of cracks forming on the discs and the pads detaching. Thermal shock may also be a part of the Rally Sweden: if it snows heavily, the backend of the car moves a great deal and can end up hitting the piles of snow that come into contact with the rear brakes. Yet, when there is a lot of snow, the grip is low. If the snowfall is light, the rivets penetrate more easily into the compact dirt, increasing grip.



The combination of these two elements leads to a medium level of difficulty for the braking systems. Among the least challenging races for the braking systems are the Wales Rally GB and Rally Finland.



The first is famous for the mud which makes it especially slippery and devoid of grip. The Rally of the Thousand Lakes, on the other hand, has very fast lines but the street surfaces are slippery because they are covered in gravel that destroys the grip of the first cars that pass through.
