  Q: How to replace the rear brake disc on Chevrolet Silverado 3500 Classic?

  A:

  To replace the rear Brake Disc, collect the following tools: slide hammer with adapter (J 2619-01) and disc resurfacing kit (J 41013), wheel hub resurfacing kit (J 42450-A); disc removal tool (J-46277). Start by depowering the park brake and checking the Brake Master Cylinder reservoir fluid level should be in the middle point between the most upper and most lower limits. Mark the disc's relationship to the hub, take off the tire and wheel assembly. Use a large c-clamp so you can compress the brake caliper pistons then remove the Brake Caliper Bracket and the brake caliper and bracket as an assembly to support the caliper as part of the brake caliper without disconnecting the Hydraulic Hose. If it applies, remove Brake Disc retaining push nuts, and if it is required, apply a deadblow hammer to split the disc from the hub. In case the disc cannot be disassembled, assemble the disc removal tool (J-46277) and attach it to the slide hammer with adapter (J 2619-01) and push the tool between the disc friction surfaces to facilitate its removal. Examine the park brake parts for any damage, and replace damaged ones if necessary. Clean the hub/axle flange and Brake Disc mating surfaces with the aid of the wheel hub resurfacing kit (J 42450-A) and disc resurfacing kit (J 41013) to remove rust and contaminants. Line up and mount the disc and check the assembled lateral runout (LRO) for best brake performance. Forward any deviation in specifications of the lro to be corrected. Install the caliper and the caliper bracket, keeping in mind to clean the bolting threads and apply threadlocker gm p/n 12345493 (Canadian P/N 10953488) while tightening the caliper bracket bolts to 200 nm (148 ft. Lbs.). Finally, replace the tire and wheel assembly and pedal the brake pedal slowly to seat the caliper pistons and pads before topping off the master cylinder reservoir with clean brake fluid if needed.

  Q: How to replace the front brake disc on the 25/3500 Series on Chevrolet Silverado 3500 Classic?

  A:

  To replace the front Brake Disc of the 25/3500 series you need j 41013 rotor resurfacing kit (J 41013) and j 42450-a wheel hub resurfacing kit (J 42450-A) tools. Clear the friction surface of the new disc by soaking it with brake cleaner or denatured alcohol. Disassemble the tire wheel and hub unit and remove the front wheel extension housing when present. Drive a large screwdriver into the disc to block rotation as you measure how the hub extension fits with the hub. Strike the hub extension gently with a rubber mallet to take it off its position after unhitching its mounting nuts. Look at the brake master cylinder reservoir fluid and drain extra fluid as needed. Apply two large c-clamps to stop brake caliper pistons and position the disc over the hub. Unite caliper and caliper bracket as one part and remove them together without disconnecting the brake hose. Remove associated Brake Disc locking nuts first then hit the disc-mate hub with a soft mallet if required. To remove a corroded disc fully use penetrating oil and force it off with two bolts t10 x 1.5. Apply j 42450-a and j 41013 kits to remove all rust and residue from hub flange and disc connection areas. You must put the hub flange through a quality inspection to remove any nicks and marks before fixing the disc position. Test the assembled disc side-to-side movement and resolve it when measurements exceed standard values. Clean and put threadlocker gm p/n 12345493 (Canadian P/N 10953488) on the caliper bracket bolts before fixing it back on the vehicle and tightening the bolts to 300 nm (221 ft. Lbs.). Carefully put back the front wheel hub extension of dual wheel vehicles while placing it in its normal position and tighten the nuts to 130 nm (96 ft. Lbs.). Put back the tire and wheel unit before slowly pressing the brake pedal to adjust the caliper piston position and check the master cylinder reservoir fluid level.
