  Q: How to replace the rear brake disc (RPO Codes J65, JL9) on Chevrolet Uplander?

  A:

  To perform Brake Disc replacement on the rear axle (J65 and JL9 variants) start by lifting and stabilizing the vehicle. Crank the tire off and wheel yet support the brake caliper with mechanics wire to avoid damaging the hydraulic hose during Brake Caliper Bracket bolt removal. Separate the brake caliper assembly from the knuckle to remove all strain from the hydraulic brake hose while working. Before taking off the Brake Disc line up its position with the wheel studs and try rotating the disc as you gently pull it aside. Wipe away all rust and dirt deposits from both the wheel hub and Brake Disc assembly areas using the wheel hub resurfacing kit (J 42450-A) and the rotor resurfacing kit (J 41013). Check the disc and hub surfaces for foreign material before fitting the disc to its mounting position. Position the disc correctly on the hub using the matchmarks as reference. Check the lateral runout of the Brake Disc when attached to the hub. Make any needed adjustments when the results surpass the technical standards. Put the brake caliper and bracket set on the knuckle suspension before adding back the tire and wheel system. End the process plus start smooth Brake Pad action if you replaced Brake Disc or fitted new brake pads.

  Q: How to replace the front brake disc on Chevrolet Uplander?

  A:

  First, lift and support the car before you replace the front Brake Disc. Take off the wheel and the tire. Compress the piston into the caliper bore with a c-clamp, so the caliper can slide off, then take out the c-clamp. Make sure you use heavy mechanic's wire or another suitable option to hold the caliper and protect the hose. Take off the caliper bracket bolts without loosening the hose, then pull out the brake caliper and bracket together from the suspension knuckle, keeping the brake hose relaxed. Put matchmarks on the Brake Disc and the wheel studs, then remove the Brake Disc. Use the wheel hub resurfacing kit (J 42450-A) and the rotor resurfacing kit (J 41013) to scrub the hub and disc mating spots clean of any rust or contaminate. Look over the mating surfaces to be certain no particles are left, then mount the disc to the hub/axle flange with the help of the matchmark. Check the assembled lateral runout (LRO) of the Brake Disc to be sure it meets the requirements for good performance; should it go past the set standard, change it as necessary. Put the brake caliper and its bracket back on the suspension knuckle as an assembly, and then fit the tire and wheel. At the end, lower the vehicle and, whenever required, burnish both the pads and discs.
