New Or Old, Rotors Must Be Measured
Measuring the rotor thickness should be part of any brake job. Even if it looks like it is below specifications, it should be measured and documented on the repair order. This can be the best sales tool and the best defense against a customer claiming that you replaced their rotors unnecessarily.
Brake Job: 2009-2015 Honda Pilot
The second-generation Honda Pilot shares the same platform as the Odyssey minivan and Accord. It also shares a lot of the same complaints concerning “warped” rotors. It is not excess heat that causes brake judder and pulsation, it is lateral runout and disc thickness variation (DTV). The Pilot is sensitive to disc thickness variation. This
Change Your Mind When It Comes To Rotors and Pulsation Comebacks
How do you handle a pulsation or comeback? Blame the pads? The driver? Defective rotor? When you point your finger at these items, there are three fingers pointing back at YOU. How much stock do you put into these common shop myths about brake rotors?
Finding, Fixing Runout and Disc Thickness Variation
Now that the warped rotor myth is busted, and we’re not just replacing the rotor and moving on, what are we doing instead? Measuring runout First, check for rotor surface runout with the wheel mounted. Components should be marked as you perform an inspection of the assembly. By measuring the rotor on the hub, you
Stop the ‘Warped’ Rotors Myth and Service Brakes the Right Way
Myths take hold because either A) they seem completely logical or B) they are so often repeated that they just become common knowledge. The warped rotor myth is a little bit of both. A rotor that contributed to a pulsation condition certainly appears “warped.” Plus, everyone says it — even technicians that know the rotor

Brake NVH: Real World Applications
First know that all brakes make noise. When the friction material makes contact with the rotor, the coupling causes the brake pad and rotor to oscillate and vibrate. The components are locked as a combined system that will vibrate at the combined system’s natural frequency of vibration. This is called force-coupled excitation. The driver hears
Avoid The ‘Warped Rotors’ Trap, Find True Pulsation Cause
The expression “warped rotors” still seems prevalent in the brake service community. According to common lore, a warped rotor is the usual cause for pedal pulsation or vibration in the car or steering wheel that motorists experience during braking. In cases relating to the brake system sometimes caused by worn suspension components, the cause for
Pulsation and Judder: Ask the right questions to improve your sales and diagnostics
Whenever a customer comes to your shop for any brake repair, you need to know why they are there in the first place. Just writing a ticket for a brake job because the customer requested it can lead to a comeback and an unsatisfied customer. There is one golden question every service writer must ask
ASE A5 Test Prep: Brake Pulsation And Runout
Being able to diagnose and solve brake rotor pulsation problems is critical to passing the ASE A5 exam for brakes. Pulsation and brake performance problems may not seem to be the most difficult, but they often cause the most headaches for technicians. Below are sample questions based on the A5 task list, written by the editors
