How to Change Rear Brake Rotors on an Uplander Van

Iskandar Blogger 9:05 AM

Rear brakes account for about 25 to 30 percent of the braking power on the Uplander, so when the rotors begin to warp or become excessively scored, you'll want to replace them. Rotors are discs that are secured to the wheel hub. On the Uplander, the wheel and the caliper hold the rotor in place, while the caliper and brake pad applies clamping force to the rotor.

Instructions

    1

    Loosen the rear wheel lug nuts by turning them 45 degrees counterclockwise with a tire wrench. Do not unseat the wheel from the wheel hub assembly.

    2

    Place the floor jack under the rear jack point and raise the van into the air.

    3

    Place jack stands under the rear pinch welds.

    4

    Lower the van onto the stands and finish removing the lug nuts. Pull the wheel off the wheel hub assembly.

    5

    Remove the mounting bolts on the brake caliper and slide the caliper off the rotor.

    6

    Secure the brake caliper to the coil springs above the brake system with zip ties.

    7

    Remove the brake rotor by sliding it straight off the hub. You may need to use a rubber mallet to persuade the rotor to come off the hub assembly.

    8

    Install the new rotor and reassemble the brake assembly. Installation is the reverse of removal.

    9

    Spray the entire brake hub assembly with brake parts cleaner. Remove all traces of oil, dust, dirt and debris.

    10

    Mount the wheel back on the wheel studs by lining up the holes on the wheel to the studs on the hub assembly and tighten the lug nuts down.

    11

    Lower the Uplander to the ground and torque the lug nuts to 100 foot-pounds. To do this, set the dial on the torque wrench to 100 foot-pounds. Place the socket end of the wrench over the lug nuts and turn them clockwise until the clutch disc in the head of the torque wrench slips. You will hear an audible clicking sound.
