One of the most frequent calls we get is “how much will you charge to put new brake pads on my car?” It’s one of my least favorite questions.

First, my goals are customer satisfaction and safety. Just doing what we in the business call a ‘pad slap’ doesn’t lead to the safest, or the most satisfactory job. That’s because brake systems are subjected to extreme heat, often more than 500 degrees. They are also out in the open where dust, dirt, oil, gravel, and other contaminants are ground into them. Under these conditions, the metal of the brake rotors [the big metal discs inside the wheels] changes. It will get scratched, glazed, and often even warped. Look at the brake rotors on a new car or one that has just had a proper brake job. The surface looks a little dull. That’s because its surface is actually cut with a cross hatch of microscopic grooves to increase the friction of the rotor when the pads are pushing against it, helping the car stop faster. Now look at the surface of a brake rotor that’s been on the road for a few years. It will be shiny. It has actually become too smooth. The pads won’t be able to bite as well and the car won’t stop as quickly. Sometimes the rotor will have a bluish tint. That’s a sign it’s been overheated, and the metal has changed. Those rotors have frequently warped under that excessive heat, leading to squealing or pedal pulsation. Under these conditions just replacing the brake pads will often lead to a dissatisfied customer.

When we do a brake job we also clean and lubricate all the sliding surfaces. That allows the parts to move smoothly together, leading to both better braking and longer brake life. And we check the brake hoses for cracks and bulges, the calipers for leakage or binding, and the condition of the fluid and master cylinder and wheel cylinders. All that is part of a proper brake job.

Finally, there are different options as to the type and quality of parts. Pads come in ‘organic’, ceramic, and semi-metallic compositions, rotors can be solid, vented, or slotted. It will often take a discussion with the client to determine which are the appropriate parts for your use. And sometimes manufacturers will change the size of their brakes in mid-year and we have to measure them to find the right part.

So the real answer to their question is ‘We have to look at your car and consult with you.’ Anything less won’t give you the real answer.
