🔧 Front Brake Pads & Rotors - Replacement

On your Sierra, the front brake pads and rotors are a straightforward service, but you need to retract the caliper carefully and support it so the brake hose is not stretched. Since this truck uses larger front brakes, keep the work area clean and follow the torque steps closely.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

⚠️ Safety & Precautions

• Lift the truck on level ground and support it with jack stands before removing any wheels.
• Do not let the caliper hang by the brake hose.
• Keep grease and brake cleaner off the rotor and pad friction surfaces.
• If your truck has a brake wear sensor on the front pads, disconnect it carefully before removal.
• Battery disconnect is not required.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the front wheel

• Use a 21mm socket and breaker bar to loosen the lug nuts if needed, then remove them.
• Take off the wheel and set it aside.

Step 2: Remove the brake caliper

• Use an 18mm socket to remove the caliper slide pin bolts.
• Lift the caliper off the bracket and hang it with a bungee cord or mechanic's hook.
• Never let the hose carry the weight.

Step 3: Remove the caliper bracket

• Use an 18mm socket to remove the caliper bracket bolts.
• Remove the bracket from the steering knuckle.
• Torque on installation: 190 Nm (140 ft-lbs)

Step 4: Remove the rotor

• Pull the rotor off the hub.
• If it is stuck, use a rubber mallet to tap the rotor hat area.
• Clean the hub face with a wire brush and brake cleaner.
• A clean hub prevents brake pulsation.

Step 5: Install the new rotor

• Clean the new rotor with brake cleaner to remove shipping oil.
• Install the rotor onto the hub.
• If equipped, hold it in place with a wheel lug nut finger-tight while you work.

Step 6: Install the caliper bracket

• Reinstall the caliper bracket using the 18mm socket.
• Torque to 190 Nm (140 ft-lbs).

Step 7: Compress the caliper piston

• Use a caliper piston compression tool to slowly push the piston all the way back.
• Watch the brake fluid reservoir so it does not overflow.
• Compress slowly and evenly.

Step 8: Install the new pads

• Apply a thin layer of brake grease to the pad contact points on the hardware only, not the friction surface.
• Install the new pads into the bracket.
• If your pads have a wear sensor, reconnect it now.

Step 9: Reinstall the caliper

• Slide the caliper over the new pads.
• Install the caliper slide pin bolts using the 18mm socket.
• Torque to 43 Nm (32 ft-lbs).

Step 10: Reinstall the wheel

• Put the wheel back on and hand-start the lug nuts.
• Lower the truck and use a torque wrench with a 21mm socket to tighten the lug nuts in a star pattern.
• Torque to 190 Nm (140 ft-lbs).

Step 11: Repeat on the other side

• Replace the front brakes and rotors in pairs.
• Repeat the same process on the opposite front wheel.

✅ After Repair

• Press the brake pedal several times before moving the truck.
• Check brake fluid level and top off if needed.
• Test for normal pedal feel at low speed.
• Listen for any scraping or clicking noises.
• Perform a gentle brake break-in for the first 200 miles.
