2006 Buick LaCrosse Parts Questions & Experts Answers

• Q: What Tools Are Required to Service and Repair the Brake Disc, and What Steps Should Be Followed to Ensure Optimal Brake Disc Performance on 2006 Buick LaCrosse?

  A: Brake disc maintenance needs both the Disc Resurfacing Kit (J41013) and Wheel Hub Resurfacing Kit (J42450-A). The regular brake system maintenance does not need to include disc refinishing on disc brakes. Also avoid resurfacing new disc brake discs. Refinishing needs to happen when your disc is sufficiently sturdy and features too much variation in thickness or shows extensive corrosion, fractures, color changes from blueing, and deeper-than-acceptable scoring. Use J42450-A Wheel Hub Resurfacing Kit to scrape away any rust and corrosion from the hub/axle flange sanding surface. You need to employ the Disc Resurfacing Kit (J41013) for degreasing all parts that attach to the brake disc. Check the brake surfaces for impurities before you mount the disc to the brake lathe following good attachment hygiene practices. Follow the lathe equipment guidelines to insert cutting tools on the disc surfaces until you see a surface mark that confirms good tool alignment. Fasten the disc to the lathe according to the manufacturer's manual while checking thickness after every grinding cycle. When the disc reaches its minimum allowed thickness after refinishing it needs to be replaced. You need to follow the operating speeds and use either a 120 grit aluminum oxide non-directional tool or a 150 grit aluminum oxide sanding block to achieve a non-directional result. After cleaning the disc brake friction surfaces with denatured alcohol or brake cleaner you should remove the disc from the lathe to measure the assembled lateral runout. Correct the runout if it reads higher than the permitted specs to keep brakes functioning properly.
