🔧 Frontier - Rear Brake Pad Replacement

On your Frontier, the factory rear brakes are typically drum brakes, which use brake shoes (not pads). Replacing the rear “pads” usually means replacing the rear brake shoes + hardware, then adjusting them so the pedal feel and parking brake work correctly.

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

⚠️ Safety & Precautions

• ⚠️ Support the truck with jack stands; never rely on a jack.
• ⚠️ Release the parking brake before removing drums, or they can’t come off.
• ⚠️ Avoid breathing brake dust—use brake cleaner, not compressed air.
• ⚠️ Work one side at a time so you can use the other side as a reference.
• ⚠️ If brake fluid is leaking at the wheel cylinder, stop—shoes won’t fix that.

📋 Before You Begin

• Park on level ground, put the transmission in P, and chock the front wheels.
• Make sure the parking brake is fully released.
• Loosen rear lug nuts slightly before lifting (use 21mm socket and breaker bar).
• Lift the rear axle and set it on jack stands under the axle tubes.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear wheels

• Remove the lug nuts using a 21mm socket.
• Remove both rear wheels and set them aside.

Step 2: Remove the brake drum

• Try pulling the drum straight off by hand.
• If stuck, tap around the drum “hat” with a hammer to break rust loose.
• If it still won’t come off, the shoes may be adjusted too tight—use a brake adjusting spoon through the backing plate adjuster slot (rear of the assembly) to back off the star wheel. Small moves make a big difference.
• Once removed, spray inside the drum with brake parts cleaner.

Step 3: Document the spring layout

• Take a clear photo of the springs, adjuster, and parking brake lever before disassembly.
• This is your “map” for reassembly.

Step 4: Remove the return springs and hold-down springs

• Remove the large return springs using brake spring pliers (specialty).
• Remove the shoe hold-down springs using a drum brake hold-down spring tool (specialty) (this tool pushes and twists to release the retaining cup). Press firmly; keep it centered.
• Use needle-nose pliers and a flat-blade screwdriver as needed, but keep control of springs—they can snap loose.

Step 5: Remove the shoes and adjuster

• Lift the shoes away from the backing plate and remove them.
• Remove the star-wheel adjuster assembly and set it aside.
• If the parking brake lever is attached to one shoe, transfer it to the new shoe (use needle-nose pliers and a flat-blade screwdriver to remove the clip).

Step 6: Inspect key parts (don’t skip)

• Check the wheel cylinder (the small hydraulic cylinder at the top): if you see wet brake fluid, it needs repair before continuing.
• Check the backing plate “shoe pads” (where the shoes rub). Clean with wire brush and brake cleaner.
• Check the drum surface for deep grooves or heavy heat spots. Replace drums if badly worn.

Step 7: Lubricate the contact points

• Apply a very thin film of high-temp brake grease to the backing plate shoe contact pads (not on the friction lining).
• Keep grease off the shoe lining and drum surface—clean with brake cleaner if you get any on them.

Step 8: Install the new shoes and hardware

• Install the new shoes onto the backing plate.
• Install the hold-down pins/springs using the drum brake hold-down spring tool (specialty).
• Install the adjuster in the same orientation as it came out.
• Install the return springs using brake spring pliers (specialty), matching your photo and the hardware kit layout.

Step 9: Pre-adjust the shoes

• Turn the star wheel with the brake adjusting spoon (specialty) to expand the shoes until the drum is a snug fit.
• Install the drum and spin it by hand: you want a light, even drag—not locked up.

Step 10: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-start all lug nuts.
• Lower the truck enough for the tires to touch the ground and torque lug nuts in a star pattern using a torque wrench: Torque to 133 Nm (98 ft-lbs).

✅ After Repair

• Pump the brake pedal 10-15 times before driving until it feels firm.
• Check the parking brake: it should hold the truck on a gentle incline. If it’s weak, the shoes may need a little more adjustment.
• Do a slow test drive in a safe area. Listen for grinding or pulling.
• Recheck lug nut torque after a short drive: 133 Nm (98 ft-lbs).
