⚠️ Safety & Precautions

• ⚠️ Support the truck with jack stands; never rely on a jack.
• ⚠️ Do not inhale brake dust; use brake cleaner, not compressed air.
• ⚠️ Never let the brake caliper hang by the rubber hose; support it with a strap.
• ⚠️ Do not press the brake pedal while the caliper is off.
• ⚠️ Work on one side at a time so you can reference the other side.
• 🔋 Battery disconnect is not required for this job.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Place wheel chocks behind the rear tires using wheel chocks.
• Crack the front lug nuts loose 1/2 turn with a 22mm socket and breaker bar before lifting.
• Open the hood and check the brake fluid level; it may rise when you compress the piston.
• C-clamp compresses the caliper piston back in.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Lift the front using a floor jack (rated 3-ton minimum) at the proper front jacking point.
• Set the truck onto jack stands (rated 3-ton minimum).
• Remove the front wheels using a 22mm socket and ratchet.

Step 2: Remove the brake caliper

• Turn the steering wheel to give yourself more space at the side you’re working on.
• Remove the two caliper slide pin bolts using a 13mm socket and ratchet.
• Lift the caliper off the bracket and hang it from the suspension using a bungee cord.

Step 3: Remove the old pads and hardware

• Slide the pads out of the bracket by hand; use a flathead screwdriver if they’re stuck.
• Remove the stainless pad clips (hardware) from the bracket.
• Clean the bracket pad “rails” using a wire brush and brake cleaner spray.

Step 4: Remove the caliper bracket

• Remove the two caliper bracket bolts using an 18mm socket and breaker bar.
• Set the bracket aside.
• When reinstalling later, apply medium strength threadlocker to the bracket bolt threads.
• Torque to 221 Nm (163 ft-lb) for the caliper bracket bolts.

Step 5: Remove the rotor

• Pull the rotor straight off the hub by hand.
• If it’s rust-stuck, spray the hub/rotor center area with brake cleaner spray and use gentle rocking; if needed, tap the rotor hat with the handle of a breaker bar to break rust loose.
• Clean the hub face with a wire brush so the new rotor sits flat. A dirty hub can cause pedal pulsation.

Step 6: Install the new rotor

• Clean both faces of the new rotor with brake cleaner spray to remove protective oil.
• Install the rotor onto the hub.
• To keep it from wobbling, thread on two lug nuts backwards by hand (temporary) and snug them with a 22mm socket.

Step 7: Service the slide pins and reinstall the bracket

• Pull the caliper slide pins out of the bracket by hand.
• Wipe them clean and apply a thin coat of brake caliper slide pin grease (silicone).
• Reinstall the pins and make sure they move smoothly.
• Reinstall the caliper bracket using an 18mm socket and ratchet.
• Torque to 221 Nm (163 ft-lb) for the caliper bracket bolts.

Step 8: Install new hardware and pads

• Snap the new pad clips into the bracket by hand.
• Apply a very light smear of brake caliper slide pin grease (silicone) to the pad contact points on the clips (not on the pad friction material).
• Slide the new pads into place.

Step 9: Compress the caliper piston and reinstall the caliper

• Place the old inner pad against the piston, then use a C-clamp (6" minimum) to slowly compress the piston fully back into the caliper.
• Watch the brake fluid reservoir under the hood; if it gets too high, remove a little fluid into a catch pan.
• Reinstall the caliper over the new pads.
• Install the caliper slide pin bolts using a 13mm socket and ratchet.
• Torque to 31 Nm (23 ft-lb) for the caliper slide pin bolts.

Step 10: Reinstall the wheel and torque lug nuts

• Reinstall the wheel and hand-thread all lug nuts.
• Lower the truck off the stands using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a torque wrench (20-250 ft-lb range).
• Torque to 190 Nm (140 ft-lb) for the lug nuts.

Step 11: Repeat on the other side

• Repeat Steps 1-10 on the other front wheel.
• Use the same tools and the same torque specs.

✅ After Repair

• With the engine off, pump the brake pedal 10-15 times until it feels firm. This seats the pistons to the pads.
• Check brake fluid level and top off only if needed.
• Start your Sierra 1500 and do a slow test in a safe area.
• Pad bedding (break-in): make 8-10 medium stops from 40 mph to 10 mph, driving 30 seconds between stops to cool, then avoid hard braking for the first 200 miles.
• Listen for grinding/squeal and re-check for any looseness.
