Question 1

How to replace the rear brake disc on Chevrolet Suburban 2500?

Accepted Answer

The first step to replace a rear brake rotor consists of releasing the park brake system then securely lifting the vehicle. Start by removing both tire and wheel components while registering the rotor position relative to the hub. Using heavy mechanic's wire you should support the brake caliper during bolt removal of the Brake Caliper Bracket while keeping the hydraulic flexible brake hose from harm. Support the brake caliper along with its bracket as an assembly by using heavy mechanic's wire before you disconnect the hydraulic brake flexible hose. Welded rotor retaining push nuts should be taken off the wheel studs when necessary. A deadblow hammer may help separate hub and rotor through impact at the end of the hub to remove the rotor. Then pull the rotor away from the axle while slowly turning it. To install the components first clean up the mating surface of rotor and flange by using wheel hub resurfacing kit (J42450-A) and rotor resurfacing kit (J41013). First install the rotor through slow rotation with moving it toward the axle before installing the caliper assembly and bracket. You must remove every piece of the original adhesive from the caliper bracket mounting bolts then soak the threads of these bolts with brake parts cleaner before adding threadlocker gm p/n 12345493 (Canadian P/N 10953488) to the threads. The Brake Caliper Bracket mounting bolts need to be tightened to 175 nm (129 ft. Lbs.) when using the 15 series while the 25 series requires 300 nm (221 ft. Lbs.). Lower the vehicle and reattach the tire and wheel assembly before turning the ignition off and putting a gradual brake pressure of two-thirds to the pedal. A firm pedal will result from a 15-second brake pedal application repetition to properly install brake caliper pistons and brake pads while the brake master cylinder requires a proper fill-up with clean brake fluid.

Question 2

How to service and repair the Brake Disc using the J41013 and J42450-A kits on Chevrolet Suburban 2500?

Accepted Answer

You need the j41013 disc resurfacing kit (J41013) to remove wheel bearing flange corrosion and j42450-a Wheel Hub resurfacing kit (J42450-A) to cleanse the Brake Disc mounting area and surface when servicing and fixing the Brake Disc system. Check brake discs for damage and worn surface when you test their flatness and required minimum thickness after resurfacing them. When corrosion, cracks, or depth scores pass the manufacturer-approved values need repair focus on the Brake Disc. Clean all attachments before fitting that part to your brake lathe as per the official guidelines. Bring the tools into contact with the disc friction surface while the lathe is running and check the witness mark to verify the right mounting position. Continue disc refinishing per manufacturer guidelines while measuring depth after every cut and replace the component when minimum thickness limits are broken. Try a non-directional achievement by using suggested speed controls when you sand with 120 grit aluminum oxide or 150 grit aluminum oxide sandpaper through the specific tools. You should finish cleaning each gripping surface of the Brake Disc by wiping it with denatured alcohol or brake cleaner.
