And this is why we service and WOF cars
Here’s is a great pic and a great example as to why cars get inspected like they do. On older cars with brake drums and shoes, the car had a way of telling you there was a problem. the brake pedal travel would get longer as the shoes wore out. The handbrake might not hold like it used too. The pedal may go soft or spongy.
In a modern car with disc brakes all around you can virtually have no brake linings left, but still have brakes that perform well, as was the case with the car in the picture below. By design the brakes are continuously adjusting as the pads wear. So they don’t go out of adjustment like an older car might. These brakes pictured well and truly passed the WOF brake test on our electronic gauge, however on the visual inspection they are about as low as you would dare to go and in fact were failed a WOF.
Other factors here too are this is only 1 of 4 pads in the front, and the pads don’t always wear evenly so often the one we cant see easily is worse off.
