Juddian my best effort was a small piece written in T&D many years ago.Fuel tanker in Lymm, unit brakes red hot,trailer brakes freezing and loaded
with 30,000 litres of petrol,Hoyer were not overly pleased by my comments but sorted their outfits out rather quickly.Braking is a marriage between
front and rear and electronics don’t sort it completely which is probably why Sally Traffic can report up to a dozen rigs rolled over some days and I
don’t blame drivers but would like the rig for a few hours to carry out simple tests,not IF brakes are working but WHEN.
