🔧 Front Brake Pads - Replacement
Replacing the front pads on your Sierra means removing the front caliper, swapping the pads and hardware, then compressing the caliper piston before reassembly. This is a straightforward brake job, but cleanliness and correct torque are critical for safe braking and even pad wear.
Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours
⚠️ Safety & Precautions
- Work on a flat surface and chock the rear wheels.
- Use jack stands; do not rely on a jack alone.
- Brake dust can be harmful. Do not blow it off with compressed air.
- Do not let the caliper hang by the brake hose.
- Front brakes do not use the parking brake system, but keep the truck secure in Park with the wheels chocked.
- If the brake pedal feels soft after service, do not drive until the pedal is firm.

- Break the front lug nuts loose before raising the truck.
- Assumption: stock front brake setup on your Sierra.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Loosen the front wheel
- Use a 22mm socket or lug wrench to loosen the front lug nuts slightly while the tire is still on the ground.
- Do not remove them yet.
Step 2: Lift and secure the truck
- Use a floor jack to lift the front of the truck at the proper frame or crossmember lift point.
- Set the truck on jack stands.
- Remove the wheel with the 22mm socket.
Step 3: Remove the caliper
- Use a 13mm socket and ratchet to remove the caliper slide bolts.
- Lift the caliper off the bracket carefully.
- Hang the caliper with a bungee cord or mechanic’s wire.
- Never let the hose carry the weight.
Step 4: Remove the old pads and hardware
- Pull the old pads out of the caliper bracket.
- Use a flat blade screwdriver to remove the pad clips if needed.
- Remove any anti-rattle hardware from the bracket.
Step 5: Clean and inspect the bracket
- Use a wire brush to clean rust from the pad contact points.
- Spray the area with brake cleaner.
- Check the rotor surface for deep grooves, heavy rust, or cracks.
Step 6: Compress the caliper piston
- Use a C-clamp or disc brake piston tool to slowly push the piston fully back into the caliper.
- Place the old pad against the piston so the tool presses evenly.
- Compress slowly to avoid seal damage.
Step 7: Install new hardware and pads
- Install the new pad hardware from the front brake pad hardware kit.
- Install the new inner and outer pads into the bracket.
- Make sure the pads sit fully in the clips and move freely.
Step 8: Reinstall the caliper
- Slide the caliper back over the new pads.
- Use the 13mm socket to reinstall the slide bolts.
- Torque to 31 Nm (23 ft-lbs).
Step 9: Reinstall the wheel
- Put the wheel back on by hand.
- Snug the lug nuts with the 22mm socket.
- Lower the truck and then torque lug nuts to 190 Nm (140 ft-lbs) in a star pattern.
Step 10: Seat the pads
- Press the brake pedal slowly several times until it feels firm.
- Check brake fluid level in the master cylinder and top off if needed.
- Torque the caliper bracket bolts only if removed: 200 Nm (148 ft-lbs).
✅ After Repair
- Before moving the truck, pump the brake pedal until it is firm.
- Check both front wheels for proper rotation and no dragging.
- Do a slow test drive and confirm the brakes stop smoothly.
- For the first 200 miles, avoid hard stops unless needed for safety.
