Proposal to amend Annex 3, paragraph 1.1.1. to delete the sub-paragraph referring to bedding of brake linings according to manufacturer’s instructions. A defined bedding procedure of brake linings was introduced in paragraph 1.1.2. of Annex 3 with Supplement 9 to the 01 series of amendments to UN Regulation No. 90. The last sub-paragraph of paragraph 1.1.1 had not been deleted in Revision 2 and 3 of UN Regulation No. 90, leading to different interpretations of the bedding procedure, which this proposal resolves.
