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

  A:

  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.

  Q: How to replace the front brake disc on Chevrolet Avalanche 2500?

  A:

  Both rotor resurfacing kit (J41013) and wheel hub resurfacing kit (J42450-A) represent the necessary tools required for front brake rotor replacement. The vehicle needs to be raised for support so the operator can remove the tire wheel assembly. Trace the rotor position regarding the hub and take out the two caliper bracket mounting bolts. Secure the brake caliper to a safe position using heavy mechanic's wire in order to protect the hydraulic flexible brake hose. Install the disassembly of the brake caliper together with its mounting bracket while maintaining connection of the hydraulic brake flexible hose. The rotor retaining push nuts attached to wheel studs should be removed if they exist. The resistance of the rotor to move because of corrosion requires cleaning all surfaces followed by penetrating oil application after inserting two m10 x 1.5 bolts (jack screws) into rotor holes and equal tightening will detach the rotor from the hub. To perform installation clean both the rotor and hub flange surface areas with wheel hub resurfacing kit (J42450-A) and rotor resurfacing kit (J41013). The installation process requires a hub flange which has no visible marks or nicks on it before rotor alignment begins. Seal the caliper bracket mounting bolts with threadlocker gm p/n 12345493 (Canadian P/N 10953488) after cleaning their threads before torquing them to 175 nm (121 ft. Lbs.) for 15 series or 300 nm (221 ft. Lbs.) for 25 series. Automatically replace the tire-wheel assembly before lowering the vehicle. Then turn off the engine while using the brake pedal in controlled applications until it reaches two-thirds of its possible travel before slow pedal release. Perform this action again to reach a stable brake pedal and use clean brake fluid to fill the master cylinder reservoir.
