In the past, organic break pads required a ‘break in’ period, but that is not the case with newer brake pad materials. The majority of modern brake pads are now made from either a semi-metallic material which produces a higher volume of brake dust, or ceramic which not only produces less dust but is also more efficient.
Here at Parker Automotive, our technicians will take your car out on the road following a brake pad replacement in order to test out the brakes before handing the car back to you. They do this to make sure that they are positioned correctly and are providing full, even contact on the brake rotor. The basic procedure is to drive the car at a steady 30mph before bringing it to a complete stop and then driving an additional quarter mile to cool the brake pads before stopping again.
One of the most common questions we hear from customers is ‘why do my breaks squeal when applied?’
The answer is simple. Whenever the brake rotor is going around and you apply the break, the metal callipers that secure the brake pads are squeezed and the contact between the pad and the moving rotor causes a squealing noise. Applying a buffer layer of ceramic lubricant will solve the problem! Whenever our technicians apply new brake pads they will use high temperature ceramic lubricant on all moving parts to avoid the squealing noise.
However, if you hear a metallic scraping when you are not breaking then it is time to head to the mechanic. Your brakes have a metal tab that indicates when brake pads are wearing thin. When you hear this noise it is time to replace your break pads. Do not dealy as you could end up wearing right into the rotors which is not only going to cause a loud growling sound, but which can be very expensive to replace!
Any time that you feel your brakes are making unexpected noises, our technicians will be only to happy to inspect them for you.
