Silverado 1500 - Rear Brake Pad Replacement 🛠️

I’ll give you a full, beginner-friendly guide for your rear pads. Your 2015 LT 4WD uses a standard hydraulic rear caliper with an integrated parking brake in the drum (inside the rotor hat), so no electric parking brake procedure is needed.

Tools & Supplies You’ll Need 🧰

• 🛞 Floor jack and jack stands (to safely lift and support the truck)
• 🔧 Lug wrench or 22 mm socket + breaker bar (for wheel nuts)
• 🔧 Socket set:
  • 13 mm socket – caliper guide pin bolts
  • 18 mm socket – caliper bracket bolts
  • 15 mm or 21 mm socket – if you remove the caliper bracket (varies slightly by axle)
• 🪛 Flathead screwdriver or small pry bar – to help slide caliper off
• 🗜️ C-clamp or disc brake piston tool – to push the caliper piston back in
• 🧴 Brake cleaner – spray can, to clean rotor and hardware
• 🧴 High-temp brake grease – for pad ears and slide pins
• 🧤 Mechanic gloves and safety glasses
• 🧽 Wire brush – to clean the caliper bracket where pads sit
• 🧰 Torque wrench – to tighten bolts correctly
• 📦 New rear brake pads (for your Silverado’s rear axle)
• 📦 Optional but recommended: new pad hardware clips (often included with pads)

Brake cleaner is a spray that removes dust and oil from brake parts. Brake grease is a special high-temperature lubricant for metal contact points.

Key Torque Specs 🔩

• 🧷 Rear caliper guide pin bolts: ~ 31 ft-lb (42 N·m)
• 🧷 Rear caliper bracket bolts: ~ 129 ft-lb (175 N·m)
• 🧷 Wheel lug nuts: 140 ft-lb (190 N·m)

Always torque bolts with a torque wrench so they’re tight but not over-tightened.

Prep & Safety Steps ⚠️

• 🧯 Park safely:
  • Park on a flat surface.
  • Put the transmission in PARK.
  • Do NOT set the parking brake (it acts on the rear wheels).
  • Chock (block) the front wheels so the truck can’t roll.
• 🔌 Pop the hood and locate the brake fluid reservoir (driver side, near firewall).
  • Remove the cap and set it loosely on top. This lets fluid move back when you push the pistons in.

Lift and Remove Rear Wheels 🛞

• 🛠️ Loosen lug nuts slightly (about 1 turn) on both rear wheels while the truck is still on the ground.
• 🛠️ Jack up the rear axle:
  • Place the floor jack under the rear axle tube (near the wheel you’re working on).
  • Lift until the tire is off the ground.
• 🛠️ Support with jack stands:
  • Place jack stands under the frame or axle on both sides.
  • Lower the truck gently onto the stands. Never work under a truck supported only by a jack.
• 🛠️ Remove the lug nuts and wheels. Set wheels aside.

Remove Rear Caliper & Old Pads 🔧

• 🧲 Locate the caliper: It’s the clamp-like part over the rotor.
• 🧲 Remove caliper guide pin bolts:
  • On the back of the caliper, find the two small bolts (top and bottom) – usually 13 mm.
  • Hold the slide pin with a wrench if it spins (often a flat or hex on the pin).
  • Remove both bolts.
• 🧲 Lift the caliper off:
  • Use a flathead screwdriver to gently pry the caliper away from the pads if it’s tight.
  • Do not let the caliper hang by the rubber brake hose.
  • Hang it with a wire, bungee cord, or set it on a stable support.
• 🧲 Remove old pads:
  • Slide the inner and outer pads out of the caliper bracket.
  • Note how they were installed (clips, shims, wear indicator location).

Inspect & Clean Hardware 🧼

• 🧴 Remove old hardware clips from the caliper bracket (the thin metal pieces the pad ears sit in).
• 🧴 Clean the bracket:
  • Use a wire brush to clean the areas where the clips sit.
  • Spray with brake cleaner and let dry.
• 🧴 Install new hardware clips (if included with pads) by snapping them into place on the bracket.
• 🧴 Check slide pins:
  • Pull the rubber boots back and slide the pins out (one at a time).
  • Wipe old grease off, inspect for rust or damage.
  • Apply a thin coat of brake grease and slide them back in until they move smoothly.

Compress the Caliper Piston 🔁

• 🗜️ Check the piston: It’s the round part inside the caliper that presses on the inner pad.
• 🗜️ Use a C-clamp or piston tool:
  • Place the old inner pad against the piston face.
  • Put the C-clamp over the back of the caliper and the pad.
  • Slowly tighten the clamp to push the piston fully back into the caliper.
  • Watch the brake fluid reservoir under the hood – if fluid gets close to the top, remove some with a clean syringe or turkey baster.
• 🗜️ Go slow so you don’t damage seals or overflow the reservoir.

Install New Rear Pads 🧩

• 🧰 Apply brake grease:
  • Put a thin layer of grease on the pad ears (the metal tabs that sit in the hardware clips).
  • Do not get grease on the pad friction surface or rotor.
• 🧰 Install pads into the bracket:
  • Slide the inner and outer pads into the hardware clips.
  • Make sure they move freely but don’t rattle.
  • If one pad has a wear indicator tab, match the position of the old one (usually on the inside pad, leading edge).
• 🧰 Reinstall the caliper:
  • Position the caliper over the new pads.
  • Line up the slide pin holes with the caliper ears.
• 🧰 Install and torque guide pin bolts:
  • Thread the 13 mm bolts in by hand first.
  • Tighten to about 31 ft-lb (42 N·m).

Repeat on the Other Side 🔁

• 🔁 Do the exact same steps on the other rear wheel.
• 🔁 Always replace brake pads in pairs on the same axle.

Reinstall Wheels & Lower Truck ⬇️

• 🛞 Clean rotors with brake cleaner to remove any grease or fingerprints.
• 🛞 Install wheels and hand-thread lug nuts.
• 🛞 Lower the truck:
  • Jack the truck slightly to remove jack stands.
  • Lower fully to the ground.
• 🛞 Torque lug nuts in a star pattern to 140 ft-lb (190 N·m).

Final Steps – Pump Brakes & Test ✅

• 🦶 Pump the brake pedal with the engine off:
  • Press the pedal slowly 5–10 times until it feels firm.
• 🧴 Check brake fluid level in the reservoir:
  • Make sure it’s between MIN and MAX.
  • Reinstall the cap securely.
• 🚗 Test drive:
  • Start the truck, move slowly in a safe area.
  • Do several gentle stops from low speed to bed in the pads.
  • Listen for grinding or odd noises; pedal should feel firm.

Pad Bedding Tip 🧠

• 🔥 Make 5–10 moderate stops from about 30–40 km/h (20–25 mph) down to 5–10 km/h, letting the brakes cool slightly between stops. This helps the new pads wear in smoothly and last longer.

If you tell me the brand/model of pads you bought, I can add any brand-specific tips (some ceramic pads like a slightly different bedding process).
