🔧 Front Brake Pads - Pad Replacement

Your front pads on the Sierra are a straightforward service, but the caliper and bracket are heavy and the brake parts must go back together cleanly. The job is mostly wheel removal, caliper removal, pad swap, and careful reassembly with proper torque.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• Support the truck securely with jack stands. Do not work with only a jack.
• Chock the rear wheels and set the parking brake.
• Do not press the brake pedal with a caliper removed.
• Brake dust may be present. Avoid breathing it in.
• Use brake cleaner only on brake parts. Keep it off rubber boots and paint.
• If the brake fluid reservoir is full, compress the caliper slowly and watch for overflow.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front of the truck

• Use the floor jack to raise the front end at the proper lift point.
• Place jack stands under the frame and lower the truck onto them.
• Remove the front wheel with the 21mm socket.
• Torque to 190 Nm (140 ft-lbs) when reinstalling the lug nuts.

Step 2: Remove the caliper

• Use the 14mm wrench or ratchet to remove the caliper slide pin bolts.
• Lift the caliper off the bracket.
• Hang it with a bungee cord or caliper hanger. Do not let it dangle by the brake hose.
• Torque to 31 Nm (23 ft-lbs) on reinstall for the caliper slide pin bolts.

Step 3: Remove the old pads and hardware

• Pull the old inner and outer pads out of the bracket.
• Remove the old pad clips with a flat screwdriver.
• Clean the bracket contact areas with wire brush and brake cleaner.
• Clean metal contact points until shiny.

Step 4: Inspect and prep the caliper

• Check the rotor surface for deep grooves, cracks, or heavy rust.
• Inspect the caliper slide pins for smooth movement.
• If the pins are dry, clean them and apply a light coat of brake grease.
• Make sure the rubber boots are not torn.

Step 5: Compress the caliper piston

• Use a C-clamp or brake caliper compression tool to slowly push the piston fully back into the caliper.
• Watch the brake fluid reservoir while compressing.
• Go slowly so fluid does not overflow.

Step 6: Install new hardware and pads

• Install the new pad clips from the brake hardware kit into the bracket.
• Apply a small amount of brake grease to the pad ears and clip contact points.
• Install the new pads into the bracket.
• Make sure the friction material faces the rotor.

Step 7: Reinstall the caliper

• Lower the caliper over the new pads using the 14mm wrench or ratchet.
• Install the slide pin bolts and tighten them evenly.
• Torque to 31 Nm (23 ft-lbs) for the caliper slide pin bolts.

Step 8: Reinstall the wheel

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

Step 9: Repeat on the other front side

• Replace the pads on the other side using the same steps.
• Always service brake pads in pairs.
