• Q: How to Change a Brake Disc on 2007 Buick LaCrosse?

  A: You should first raise the vehicle while supporting it and then remove the tire and wheel before starting the disc replacement process. Press the piston into the brake caliper using a c-clamp but not enough to cause damage. Move away the c-clamp when the operation is complete. Use strong mechanic wire or substitute to hold up the brake caliper without hurting the hydraulic flexible brake hose. Detach the caliper bracket bolts while leaving the brake hose bolt intact to take off the combined brake caliper and bracket piece from the suspension knuckle without placing tension on the hydraulic system. Position the Brake Disc on matching wheel studs and take it off from the vehicle. Clean all dust and corrosion from the hub/axle joint and Brake Disc faces before installation using the wheel hub resurfacing kit (J 42450-A) and rotor resurfacing kit (J 41013). Examine both disc surfaces before you put the Brake Disc on the hub/axle flange by lining up the matchmarks. Test the lro values of the Brake Disc system after assembly and correct the setup when measurements breach their set limits. Put the brake components back in their proper places on the suspension knuckle and add tire and wheel assemblies. As a final step lower the vehicle and prepare to smooth new disc surfaces when needed during pad Brake Pad installation.
