# Directive 2014/45/EU of the European Parliament and of the Council of 3 April 2014 on periodic roadworthiness tests for motor vehicles and their trailers and repealing Directive 2009/40/EC (Text with EEA relevance), Division 1.2: Service braking performance and efficiency

Extent: E+W+S+N.I.

1.2.1.
Performance
During a test on a brake tester or, if impossible, during a road test, apply the brakes progressively up to maximum effort.
(a)
Inadequate braking effort on one or more wheels.
X
No braking effort on one or more wheels.
X
(b)
Braking effort from any wheel is less than 70 % of the maximum effort recorded from the other wheel on the same axle. Or, in the case of testing on the road, the vehicle deviates excessively from a straight line.
X
Braking effort from any wheel is less than 50 % of the maximum effort recorded from the other wheel on the same axle in the case of steered axles.
X
(c)
No gradual variation in brake effort (grabbing).
X
(d)
Abnormal lag in brake operation of any wheel.
X
(e)
Excessive fluctuation of brake force during each complete wheel revolution.

1.2.2.
Efficiency
Test with a brake tester or, if one cannot be used for technical reasons, by a road test using a deceleration recording instrument to establish the braking ratio which relates to the maximum authorised mass or, in the case of semi-trailers, to the sum of the authorised axle loads.
Vehicles or a trailer with a maximum permissible mass exceeding 3,5 tonnes has to be inspected following the standards given by ISO 21069 or equivalent methods.
Road tests should be carried out under dry conditions on a flat, straight road.
Does not give at least the minimum figure as follows ( 1 ):
1.. Vehicles registered for the first time after 1/1/2012 :
Category M 1 : 58 %
Categories M 2 and M 3 : 50 %
Category N 1 : 50 %
Categories N 2 and N 3 : 50 %
Categories O 2 , O 3 and O 4 :
for semi-trailers: 45 % ( 2 )
for draw-bar trailers: 50 %
X
2.
Vehicles registered for the first time before 1/1/2012 :
Categories M 1 , M 2 and M 3 : 50 % ( 3 )
Category N 1 : 45 %
Categories N 2 and N 3 : 43 % ( 4 )
Categories O 2 , O 3 and O 4 : 40 % ( 5 )
X
3.
Other categories
Categories L (both brakes together):
Category L1e: 42 %
Categories L2e, L6e: 40 %
Category L3e: 50 %
Category L4e: 46 %
Categories L5e, L7e: 44 %
Category L (rear wheel brake):
all categories: 25 % of the total vehicle mass
X
Less than 50 % of the above values reached.
