BMW’s first attempt at a crossover SUV is what they call a Sports Activity Vehicle (SAV).
These brake systems are known to make noise if the proper procedures are not followed and brake materials are not installed properly. The OE pads use a Non-Asbestos Organic (NAO) compound. The NAO material provides increased resistance to brake squeal. Some customers have complained about noisy brakes on these vehicles, so it is a good idea to explain the different pad compounds and varying degrees of noise resistance to let them decide which best suits their needs.
The main culprit of friction material separation is typically corrosion.
A proper brake inspection, some common causes for brake noise and some steps that may get overlooked.
Hybrid and electric vehicles use regenerative braking to capture energy to charge the batteries.
Old rotors should be replaced or resurfaced, and the hub-mounting surface should be cleaned thoroughly.
When you install the caliper, the banjo bolt gets fed through the end of the brake hose and mounts to the inlet of the caliper.
If a customer has uneven brake wear and you just assume it is a bad caliper and replace it, you may be guessing incorrectly. Imploded brake hoses and stuck proportioning valves produce hidden symptoms that are not easily diagnosed.
A brake pad may require up to 20 different raw materials.
