🔧 1500 - Rear Brake Pads & Rotor Replacement

You’ll be removing the rear wheels, taking off the brake calipers and brackets, swapping the rotors, and installing new pads. This restores safe stopping power and prevents grinding, shaking, and uneven wear.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Support the truck with jack stands before working underneath.
• ⚠️ Chock the front wheels and keep the transmission in Park.
• ⚠️ Release the parking brake before removing rear rotors (this truck uses a cable parking brake, not an electronic one).
• ⚠️ Don’t breathe brake dust; use brake cleaner to wet it down.
• ⚠️ Never let the caliper hang by the rubber brake hose.
• ⚠️ Battery disconnect is not required.

📋 Before You Begin

• Park on level ground, set the transmission to Park, and release the parking brake.
• Place wheel chocks in front of and behind at least one front tire.
• Loosen the rear lug nuts 1/2 turn using a 21mm socket and breaker bar before lifting.
• Pop the hood and remove the brake fluid reservoir cap (this prevents pressure buildup when pushing pistons back). Use shop towels to catch any overflow.
• Do one side at a time to use the other side as a reference.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and support the rear

• Lift the rear using a floor jack (rated 3-ton minimum) under a solid rear jacking point (rear axle tube near the spring perch is commonly used).
• Set the truck down onto jack stands (rated 3-ton minimum) on both sides.
• Remove the wheels using a 21mm socket and ratchet.

Step 2: Remove the rear caliper (the squeeze part)

• Turn the steering wheel is not needed for the rear; keep access clear.
• Remove the two caliper slide pin bolts using a 13mm socket and ratchet.
• Lift the caliper off the bracket and hang it with a caliper hanger hook.
• Caliper = the part that squeezes the pads.

Step 3: Remove the pads and caliper bracket

• Pull the old pads out of the bracket by hand.
• Remove the caliper bracket bolts using an 18mm socket and breaker bar.
• Set the bracket aside on a clean surface.
• Torque to 169 Nm (125 ft-lbs) when reinstalling the caliper bracket bolts.

Step 4: Remove the rotor

• Slide the rotor off the hub by hand.
• If it’s stuck from rust, tap the rotor “hat” area with a rubber mallet while pulling outward.
• If it still won’t come off, confirm the parking brake is fully released. The parking brake shoes can hold the rotor from the inside.

Step 5: Clean the hub and prep the new rotor

• Clean the hub face with a wire brush and brake parts cleaner spray (flat, clean hub helps prevent brake pulsation).
• Apply a very thin film of anti-seize compound to the hub face (avoid getting any on wheel studs).
• Clean both sides of the new rotor with brake parts cleaner spray and shop towels to remove shipping oil.

Step 6: Install the new rotor

• Slide the new rotor onto the hub.
• To hold it steady while you work, temporarily install one lug nut backwards by hand (use the 21mm socket only lightly if needed).

Step 7: Service the bracket clips and slide pins

• Remove the old pad hardware clips from the bracket and clean the contact points with a wire brush.
• Install the new hardware clips (from the hardware kit) by hand.
• Pull the caliper slide pins out (they slide out of the rubber boots), wipe clean with shop towels, then apply a light coat of brake caliper grease (silicone brake grease).
• Slide pins = the “guides” the caliper moves on.

Step 8: Reinstall the caliper bracket

• Position the bracket over the rotor and start the bolts by hand.
• Tighten using an 18mm socket and torque wrench.
• Torque to 169 Nm (125 ft-lbs).

Step 9: Compress the caliper piston

• Place an old brake pad against the piston face, then use a C-clamp (6" minimum) to slowly press the piston back into the caliper.
• Go slowly and watch the brake fluid reservoir level under the hood.
• If the reservoir is close to overflowing, remove fluid with shop towels (do not spill on paint).

Step 10: Install the new pads and reinstall the caliper

• Install the new pads into the bracket and clips by hand (they should slide smoothly).
• Set the caliper back over the pads.
• Install and tighten the caliper slide pin bolts using a 13mm socket and torque wrench.
• Torque to 41 Nm (30 ft-lbs).

Step 11: Repeat on the other rear wheel

• Repeat Steps 2–10 on the other side using the same tools and torque specs.

Step 12: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread all lug nuts.
• Lower the truck off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a 21mm socket and torque wrench.
• Torque to 176 Nm (130 ft-lbs).

✅ After Repair

• With the engine off, slowly pump the brake pedal 10–15 times until it feels firm (this seats the pistons against the new pads).
• Reinstall the brake fluid reservoir cap and confirm the fluid level is between MIN and MAX.
• Start the truck and do a careful test at low speed first; confirm no pulling, grinding, or warning lights.
• Bed-in the pads: make 8–10 medium stops from ~35 mph down to ~5 mph, allowing a little cool-down between stops.
• Recheck lug nut torque after 25–50 miles using a 21mm socket and torque wrench: 176 Nm (130 ft-lbs).
