2005 Buick LaCrosse Parts Questions & Experts Answers

• Q: How to replace the rear brake disc (RPO J65, JL9) on 2005 Buick LaCrosse?

  A: To change the rear Brake Disc (parts J65 and JL9) you need to first jack up the vehicle and put supports under it before taking off the tire and wheel components. After taking off the bracket bolts use heavy mechanic wires to safely hold the brake caliper in place. Separate the brake caliper and caliper bracket unit from the suspension knuckle while keeping tension off the hydraulic brake flex hose. Move the Brake Disc until its studs align with wheel bolts before taking it off their seating position slowly as needed. Clean the disc connection area of the hub/axle flange with the wheel hub resurfacing kit (J42450-A) before working. You should cleanse the Brake Disc contacts using the rotor resurfacing kit (J41013). Check both surfaces before attaching the Brake Disc to the hub/axle flange using the matchmark for exact placement. When you install a Brake Disc during repair work take measurements for lateral runout to check if the brake system works at its best. Fix the runout when your readings show excess after replacement. Put the brake caliper together with its bracket on the suspension knuckle then place the wheel with tire. At last position the vehicle then make sure the new Brake Disc works properly through pad-bedding if needed.
