On the driving test I understand you are not advised to use your gears to slow you down! has any of you had brake failure? I do understand these day it does not happen "But it can" what are the new drivers supposed to do? Bazile, As Sdd has explained, it's a different issue with a HGV, you are trained to get "We Were" the best fuel returns with gear changing, as said, different when loaded, but going to what I said regards brake Failure, the HGV Driver from the Buxton Tarmac Quarry's know about this when the head from Buxton over the Cat & Fiddle to Macclesfield, there is a possibility of brake "fade" & also a loss of brakes due to the continues braking.
