Disc brake seat endurance test

D1 Composite frame and composite fork — Disc brake seat endurance test

D1.1 Requirement:

When tested by the method described in D.1.2, nor thermal deformation and fractures and cracks at the disc
brake seat in any parts of the sample.

D1.2 Test methods:

This test is made with a test speed of 12.5 km/h +/- 5%.

There by the 3,000 cycles (brake 3 sec. and release 3 sec. for 1 cycle) brake delay may not remain under a
2
value of 2.2 m/s +/- 10% whereby for the mass to be slowed down 100 kg.

An adjustment or change the wear parts of the brakes is allowed.

A wind speed of a maximum of 12.5 km/h is allowed.
