Tools You'll Need:
* Wheel Chocks: Crucial for safety!
* Jack and Jack Stands: Never work under a vehicle supported only by a jack.
* Lug Wrench: To remove the wheels.
* Caliper Compression Tool: To push the caliper piston back into the caliper bore. A C-clamp can work in a pinch, but a dedicated tool is safer and easier.
* Wrench or Socket Set: Sizes will depend on your truck, but you'll likely need wrenches for caliper bolts, rotor retaining bolts (if present), and potentially caliper bracket bolts.
* Penetrating Oil (like PB Blaster): Helpful for loosening rusted bolts.
* Gloves and Safety Glasses: Always protect yourself.
Procedure (Assuming Rotor Removal is Necessary):
1. Safety First: Engage the parking brake, chock the rear wheels, and jack up the front of the truck securely. Place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Remove the Caliper:
* Locate the caliper bolts: These typically hold the caliper to the caliper bracket (a metal piece holding the caliper to the knuckle).
* Use the correct wrench to remove the caliper bolts. Apply penetrating oil if they're stuck.
* Carefully remove the caliper. It's usually attached with a sliding pin or bolt. You might need to use a bungee cord or wire to hang the caliper out of the way to avoid stressing the brake line. Do *not* let the brake line hang freely.
4. Remove the Brake Pads: The old brake pads should now be accessible.
5. Compress the Caliper Piston: Use the caliper compression tool to push the piston back into the caliper bore. This creates space for the new, thicker pads. If you're using a C-clamp, be careful not to damage the piston seal.
6. Remove the Rotor:
* Some 1996 Silverados have a single rotor retaining bolt on the back of the rotor. If you have this, remove the bolt first.
* If there's no retaining bolt, the rotor should simply pull off. Sometimes they can stick due to rust. If needed, gently tap the rotor around its circumference with a rubber mallet to loosen it. Avoid damaging the rotor's surface if you intend to reuse it.
7. Install the New Pads and Rotor (if replacing): Reverse the removal process. Ensure the pads slide smoothly into their slots. If you're reusing the rotor, inspect it for scoring or warping and replace if necessary.
8. Reinstall the Caliper: Attach the caliper to the caliper bracket and tighten the caliper bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Tighten the lug nuts in a star pattern.
10. Lower the Vehicle: Carefully lower the truck from the jack stands.
11. Check the Brake Fluid Level: After compressing the caliper piston, the brake fluid level will increase. Check and top off the master cylinder brake fluid reservoir if needed.
12. Pump the Brakes: Gently pump the brake pedal a few times to ensure the new pads are making contact with the rotor.
Important Notes:
* Consult your owner's manual or a repair manual specific to your 1996 Silverado 4WD. This will provide diagrams and torque specifications crucial for proper repair.
* If you're unsure about any step, it's best to take your truck to a qualified mechanic. Improper brake work can be extremely dangerous.
* Always use the correct tools and follow safety procedures.
Remember, replacing brake pads and rotors is a serious task. If you’re uncomfortable with any part of the process, a professional mechanic is always the safest bet.
