Brake effort or efficiency is also tested on the mot, and for good reason. Without good brakes we are endangering our vehicles our lives and lives of other road users, so good brakes are very important. Brakes worn, seized, broken parts are all taken care of in a mot test, so little wonder that 75% of mot failures are brake parts and effort/efficiency related. At PAUL NICE MOTORS, brake disc’s and disc pads, brake linings, callipers, and cylinders, and fluid are all inspected and replaced as necessary with good quality parts, giving peace of mind that your brakes are reliable.
