Pneumatic brake
Pneumatic type “D” caliper brakes are different basically due to the dimension of the pneumatic
actuator (05, 1, 2 and 3); the table below shows the tangential force for each brake type if powered at 6
bar and considering a coefficient of friction of 0.4
TYPE
Tangential Force
D05
1600 N
D1
3800 N
D2
7500 N
D3
12700 N
Hydraulic brake
The hydraulic D3-ID caliper brake is able to apply a tangential force of 14868 N if powered at 100 bar
and considering a coefficient of friction of 0.4
Dynamic torque
The dynamic torque provided by the brake will be a function of the diameter of the disc used for each
single type of product and can be determined using the following equation:
Dynamic torque [Nm] = Tangential force [N] x ( radius of the disc [m] - 0.033 )
An error in calculation will result in a braking torque different to the desired value and a
risk to aspects of safety.
The technical department of COREMO OCMEA can provide information, suggestions and
assistance for correct application and use of the product.

Brake lining wear
The thickness of each single new lining is 11 mm. A maximum overall lining wear of 12
mm is allowed. Failure to remain within the above limit may represent a risk to aspects
of safety.
5.3.
Special note
During braking kinetic energy is converted into heat caused by friction between the surfaces of
the brake linings and the brake disc. It is therefore fundamentally important to consider the
amount of heat that can be dissipated.
