Fixed caliper brake
The fixed calliper brake is the oldest type of disc brake . While in the first versions only one piston was installed on each side, today it can be up to ten. However, they have become much smaller and lighter and do not necessarily all have an effect on one surface . They are also no longer - like the original versions - only installed in commercial vehicles , but are increasingly used in high-performance vehicles.
The name fixed caliper brake has its origins in the fact that the saddle with the piston fixed to the wheel suspension is connected. Therefore, in contrast to floating caliper brakes, pistons are required on both sides of the brake disc, which press the pads against the disc. In the case of motorcycles and particularly powerful cars, the brake disc can be axially displaceable (“floating”) to distribute the contact pressure of the pads more evenly.
