Introduction

This tutorial provides a step-by-step guide on how to replace the front brake pads and rotors on a 2020 Sierra or Silverado. Proper maintenance of your vehicle's brake system is crucial for safety and performance. This guide will walk you through the necessary tools, techniques, and tips to successfully complete the job.

Step 1: Gather Necessary Tools and Materials

Before starting the brake replacement, ensure you have all the required tools and materials:

• Tools:

  • Jack and jack stands
  • Lug wrench
  • Socket set
  • Torque wrench
  • Brake caliper tool or C-clamp
  • Brake cleaner
  • Bungee cord or rope (to hold caliper)

• Materials:

  • New brake pads
  • New brake rotors
  • Brake grease
  • Rags for cleaning

Step 2: Prepare the Vehicle

1. Park the vehicle on a flat surface and engage the parking brake.
2. Loosen the lug nuts on the front wheels using the lug wrench, but do not completely remove them yet.
3. Lift the vehicle using the jack and secure it with jack stands.
4. Remove the lug nuts completely and take off the front wheels.

Step 3: Remove the Brake Caliper

1. Locate the caliper mounting bolts and remove them using the appropriate socket.
2. Carefully slide the caliper off the rotor.
3. Support the caliper using a bungee cord or rope to avoid putting stress on the brake line.

Step 4: Remove the Old Brake Pads and Rotors

1. Take out the old brake pads from the caliper bracket.
2. If necessary, remove the caliper bracket by unscrewing the bolts.
3. Remove the old rotor by unscrewing the retaining screws if present. If the rotor is stuck, gently tap it with a hammer.

Step 5: Install New Brake Rotors

1. Clean the new rotors with brake cleaner to remove any protective oils.
2. Place the new rotor onto the hub and secure it with screws, if applicable.

Step 6: Install New Brake Pads

1. Apply a thin layer of brake grease to the backs of the new brake pads.
2. Place the new brake pads into the caliper bracket.
3. If you removed the caliper bracket, reinstall it now.

Step 7: Reinstall the Brake Caliper

1. Compress the caliper piston using a brake caliper tool or C-clamp to create space for the new pads.
2. Slide the caliper back over the new pads and rotor.
3. Tighten the caliper mounting bolts to the specified torque.

Step 8: Reassemble the Wheel

1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts onto the wheel.
3. Lower the vehicle from the jack stands.
4. Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Step 9: Test the Brakes

1. Before driving, pump the brake pedal several times to ensure proper contact between the pads and rotors.
2. Check for any unusual noises or issues.

Conclusion

Replacing the front brake pads and rotors on your 2020 Sierra or Silverado can be accomplished with the right tools and steps. Always prioritize safety and ensure everything is properly secured before driving. If you’re unsure about any part of the process, consider consulting a professional mechanic.
