How to service and repair front brake discs on Buick LeSabre?

Brake rotor refinishing becomes necessary only when any of the following conditions exist: excessive corrosion, pitting, cracks, heat spots, excessive bluing discoloration, scoring beyond maximum allowable specifications, lateral runout exceeding specifications, or thickness variation beyond specifications. When refinishing is needed for brake rotors use the Hub Cleaning Kit (J42450-A) to clean away any corrosion that exists on the brake rotor hub. Install the brake rotor to the brake lathe according to manufacturer guidelines by properly securing the anti-vibration accessories. Advanced through the lathe speed while guiding the cutting tools to touch the rotor friction surfaces and verify that mounting is correct from the witness mark. The rotor needs to be remounted when the witness mark fails to reach the three-quarter distance around its perimeter. The rotor refining process must follow manufacturer instructions while the final thickness measurement determines whether replacement is needed. The process to acquire a non-directional finish requires following speed parameters and using 120 grit aluminum oxide sandpaper through a non-directional finishing tool or 150 grit aluminum oxide sandpaper with a sanding block when no finishing tool is present. Use denatured alcohol or a brake cleaner equivalent to wipe down all friction areas immediately following completion. Remove the brake rotor from the lathe after finishing then use the Rotor/Drum Flange Resurfacing Kit (J41013) to clean any corrosion from the wheel bearing flange to prevent brake system pulsation and increased lateral runout.

How to replace the front brake disc on Buick LeSabre?

In order to change out the front brake rotor, remove the tire and wheel assembly. Use heavy mechanic's wire or an equivalent to support the brake caliper each time it is removed from its mount, but the hydraulic flexible brake hose is still attached to it, as any failure to do would damage the hose and cause it to leak brake fluid. Next, free the brake caliper from its mounting bracket and suspend it after which you should move on to unfastening the Brake Caliper Bracket assembly and the brake rotor. Clean any rust or contaminants from the wheel bearing flange and brake rotor mating surfaces with the j42450-a, then put the new brake rotor onto the wheel studs onto the wheel bearing flange, followed by the Brake Caliper Bracket assembly, and fasten the brake caliper over the bracket assembly. Finally, reassemble the tire and wheel assembly.
