Classes of vibration 5 Design and manufacture 5.1 Latch mechanism The design of the latch mechanism to retain the brake pads shall satisfy the following principle: — there shall be a positive retention (generation of strain to obtain unlocking) of the latch when in the closed position; — no single point failure of the latch mechanism and its attachment to the pad holder shall result in a loss of brake pads; — ease of operation – no special tools to open and close the latch mechanism. Preferably designed to allow use of simple flat bladed screw driver; — during pad renewal the latch mechanism should remain attached to the brake pad holder; — renewal of a defective latch mechanism should not require the dismantling of the brake pad holder from the brake unit. 5.2 Interchangeability by applying same main dimensions and geometry 5.2.1 General Brake pad holders can be designed based on different concepts. The requirements specially for interchangeability are defined below. SIST EN 16451:2015
