How can I make my brakes more responsive?

That pressure pushes smaller cylinders, which press the pads against a spinning metal disc or drum to stop the vehicle.

Are worn brake discs an MOT failure?

As an example, a loose brake disc will be a dangerous defect, a brake disc worn to below the minimum thickness will generally be a major defect and both of these will mean the car fails the MOT test. If any of the tyres look underinflated, the car will fail the test, so check the pressures.

How do I know if my brake discs are worn?

There are two ways to check for brake wear on disc brakes: by looking and by listening. First, check for wear by looking at your brake pads through the spaces between the wheel's spokes. The outside pad will be pressed against a metal rotor. Generally, there should be at least 1/4 inch of pad.
