What Leyland Daf failures look like
4,240 Leyland Daf tests on record carry the manual reference DVSA attaches to each defect. The most frequent problems were with axles, wheels, tyres and suspension on 1,284 tests (30.3%), with brakes on 1,201 tests (28.3%) and with lamps, reflectors and electrical equipment on 1,008 tests (23.8%). A test can fail on more than one thing, and an MOT can be failed on one defect while another is only advised, so these counts do not add up to the number of tests.
