Important:Only remove the necessary amount of material from each side of the rotor and notethat equal amounts of material do not have to be removed from both sides on any brakesystem using a floating caliper.
Important:In many of these instances, such a minimal amount of material is removed from therotor that customer satisfaction is not a concern for future brake services. Thisprocedure is intended to “Clean-up” the rotor surface and should be conveyed to thecustomer as such – not as “cut”, “refinish” or “machine”, which tends to be termsunderstood as a substantial reduction of rotor material/life. If the brakelathe equipment being used is not capable of removing minor amounts of material whileholding tolerances, further lathe maintenance, repair, updates or equipment replacementmay be necessary.BRAKE NOISE
Some brake noise is normal and differences in loading, type of driving, or drivingstyle can make a difference in brake wear on the same make and model. Depending onweather conditions, driving patterns and the local environment, brake noise may becomemore or less apparent. Verify all metal-to-metal contact areas between pads, pad guides,caliper and knuckles are clean and lubricated with a thin layer of high temperaturesilicone grease.Brake noise is caused by a “slip-stick” vibration of brake components. While intermittentbrake noise may be normal, performing 3 to 4 aggressive stops may temporarily reduceor eliminate most brake squeal. If the noise persists and is consistently occurring,a brake dampening compound may be applied to the back of each pad. This allows partsto slide freely and not vibrate when moving relative to each other. Use Silicone BrakeLubricant, ACDelcoP/N-88862182 (Canadian P/N-88862496) or equivalent.
The following noises are characteristics of all braking systems and are unavoidable.They may not indicate improper operation of the brake system.
