Document title Proposal for amendments to Regulations No. 90

Proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4) since such replacements must by definition have values identical to the corresponding original parts. The proposal also would change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.050 mm (the common OEM specification).
