Proposal to ensure that endurance braking is assessed in the context of the Type II-A test based on the maximum mass of the vehicle or vehicle combination.

Proposal for provisions to enable the use of approval of a park lock device as an alternative to the friction parking braking to hold the vehicle.

Proposal to permit the type approval of a park lock device as an alternative to the friction parking brake(s).

Proposal for amendments to the draft provisions on e-trailers.

Proposal to address loss of trailer friction braking efficiency due to increased use of robust endurance braking systems and electrification of trucks. The number of trucks with strong endurance braking systems and increasing electrification of vehicles with more efficient energy recuperating systems reduces the use of friction brakes. As a result, brake pads and linings in some commercial vehicles do not reach a temperature that is needed for the development of optimum brake performance. In particular in trailers, a loss of brake force develops due to brake pads and linings losing effectiveness – they “fall asleep” and need to be replaced although they are not worn out.

Proposal to resolve an inconsistency in wording across the series with regard to the parking brake performance requirement.
