I spent a significant part of my working life designing brakes for Bedford Trucks (after an even more significant period as a vehicle test engineer where I had to deal with brakes and their malfunctions).
Later, I 'crossed the table' and worked for a company who manufactured brake linings (which involved being involved with vehicle manufacturers testing the linings). We were pioneers in the use of non-asbestos materials and I oversaw the introduction of non-asbestos (sintered) linings on fleet tests.
I saw the very early introduction of disc brakes as prototypes, but have no significant experience of disc brakes on production trucks. A whole new subject:-
Apart from the basics, none of my years of experience are relevant with current new trucks . . .
