>The old adage of testers that brake pads or linings can be replaced cheaper than gearboxes is not true ...
Tell us the vehicle(s) for which a new gearbox is cheaper than new brake pads (and discs?)?
If a vehicle didn't need both brakes and gearbox, would modern vehicle makers fit them both?
Last time I went out with a Met. Police driver, he advised they were trained to use the brakes to slow a vehicle, not the gearbox.
>how do you stop with brake failures..
Brake pads and discs are wearing items. If a modern vehicle's brakes fail, they have not been serviced according to the vehicle maker's schedule?
>Guy Martin once said on TV if I can't get high mileage out of my brake pads I'm not driving properly ...
That has to do with anticipation. If hazards are anticipated so the vehicle can be allowed to slow to the correct speed for the hazard without using the brakes, rather than using fuel up to the hazard and then converting that energy into heat with the brakes, the wearing parts of the brakes will last longer.
The downside of that method is, used gently constantly, pads and shoe linings will glaze; unanticipated hazard, glazed pads and shoe linings might not stop you as quickly as ones used harder more regularly?
