How to replace the front brake disc on Buick LaCrosse?

You will need to raise the vehicle while also supporting it before taking off the tire and wheel parts. To protect both the hydraulic flexible brake hose and brake caliper turn the mount bolts loose then hold the caliper steady with strong metal wires. Begin by taking out the brake caliper and bracket together as a piece then proceed to remove the Brake Disc bolt and Brake Disc. When putting in a fresh Brake Disc you should wipe its friction surface with brand-free alcohol. Use the j-42450-a wheel hub resurfacing kit and the j-41013 rotor resurfacing kit to prepare smooth surfaces of the hub/axle flange and disc hub/axle flange. Mount the Brake Disc onto its position and tighten the Brake Disc bolt to 7 nm (62 lb in). Fit the brake caliper and bracket assembly on top of the steering knuckle before tightening new brake caliper bracket bolts to 150 nm at 111 lb ft torque with 45 degrees plus 15 degrees pretension. Reinstall the tire and wheel after putting back the Brake Pad and disc into service.

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

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.
