I called into the Tesco petrol station in Glynneath at the bottom of the A465 hill one day. There was a tanker discharging petrol. The smell of burning brakes was awful and I could see smoke still coming from the wheels. I asked the driver what was wrong and he said - oh it always does it after that hill. Needless to say when I asked him if he used his gears I was told there is no need to do that on modern lorries.................
I can remember that being built when I was a nipper, had a bird's eye view from the back of our house of most of it.
Wonder how much worse his brakes would have been if he'd come down the old Glynneath bank






trucks/busses are designed to be retarded by the engine and have exhauster brakes /electronic retarders for buses (quieter) you can come down some serious hills without touching the brakes, in fact I came down 4000 M in switzerland from well above the snowline, down a hairpins decent in an 20 ton truck and at the bottom the brakes where barely warm, I used the exhauster brake it saves wear on the brakes BUT it means the service brake which should be mainly for emergencies and is ready and more importantly cold for when mr D head pulls out or a kid runs out in front of you, if you had used the brakes for even half of the decent the service brakes would be a lot less than half as efficient and at the bottom useless, as well as having 2mm worn off them and distorted disc/ drums.
All the better to stop you with !!!
