• Q: How to replace the front brake disc on 2005 Buick LaCrosse?

  A: Vehicle maintenance requires users to lift and stabilize the vehicle before they remove the tire and wheel assembly when replacing a front Brake Disc. A c-clamp should compress the Piston toward the caliper bore which lets the caliper slide away from the disc and then you can remove the c-clamp. After disconnecting the caliper bracket bolts the mechanic should remove the brake caliper and caliper mounting bracket assembly from the suspension knuckle while using heavy mechanic's wire for supportive equipment to avoid impacting the hydraulic brake hose. Mark the relationship between the Brake Disc and wheel studs before taking it off. The wheel hub resurfacing kit (J42450-A) should be used to clean rust or corrosion from the hub/axle flange before cleaning the Brake Disc mating surfaces with the rotor resurfacing kit (J41013). Before integrating the Brake Disc into the hub/axle flange check all mating surfaces are clear of debris then use the matchmark to establish proper disc orientation. Measure the lateral runout of the assembled Brake Disc after installation when possible and adjust if measurements exceed set specifications. Reinstall the brake caliper and bracket to the suspension knuckle before installing the tire and wheel assembly followed by lowering the vehicle and conducting pad and disc burnishing when Brake Disc replacement or refinishing took place.
