🔧 Sierra 1500 - Rear Brake Pad Replacement

On your Sierra 1500, the rear brakes can be either rear disc brakes (pads) or rear drum brakes (shoes), and 2007 also has a Classic vs. New Body split that changes hardware and torque specs.

Answer the two quick questions below and I’ll give you the exact, trim-correct step-by-step with the correct torque specs.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

📋 Before You Begin

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm your rear brake type (pads vs. shoes)

• With the wheel still on, look through the wheel spokes using a flashlight (or remove the wheel with a 22mm lug wrench).
• If you see a caliper “clamped” over a rotor (flat disc), you have disc brakes (pads).
• If you see a round “drum” housing (like a metal bowl), you have drum brakes (shoes) (not pads).

Step 2: Confirm 2007 “Classic” vs New Body (needed for exact torque specs)

• Look at your VIN label date or door sticker isn’t needed—use the easiest visual: the body style.
• Classic looks like the 1999–2006 trucks (more rounded dash/front end). New Body is the newer, squarer GMT900 style.
• Reply with Classic or New Body, plus Disc or Drum.

Step 3: If you confirm “Disc”, I’ll send the exact pad replacement steps

• I’ll include the correct caliper/bracket bolt sizes, exact torque specs, and parking brake notes specific to your configuration.
• Disc brake piston compressor = tool to push piston in.

✅ After Repair

• Pump the brake pedal until it feels firm before driving.
