🔧 Frontier - Rear Brake Service (Pads/Rotors OR Shoes/Drums)

Your Frontier may have rear disc brakes (pads + rotors) or rear drum brakes (shoes + drums), depending on equipment. I’ll show both procedures—use the one that matches what you see on the truck.

Assumption: If you see a caliper squeezing a shiny disc, follow Disc. If you see a closed “can” drum, follow Drum.

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

⚠️ Safety & Precautions

• 🛑 Work on level ground; chock the front wheels.
• 🛑 Do not use the parking brake while rear brakes are apart.
• 🛑 Support the axle with jack stands; never rely on a jack.
• 🛑 Brake dust is unhealthy—use brake cleaner, not compressed air.
• 🛑 If you remove a caliper, hang it with a hook—do not let it dangle by the hose.

📋 Before You Begin

• Park on level ground, put the transmission in 1st gear, and shut the engine off.
• Chock the front wheels firmly.
• Loosen rear lug nuts with a 21mm socket and breaker bar before lifting.
• Lift the rear and support the axle on jack stands.
• Release the parking brake fully (rear brakes won’t come apart correctly if it’s applied).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear wheels

• Use a 21mm socket and ratchet to remove the lug nuts and take both rear wheels off.

Step 2: Identify your rear brake type (disc vs drum)

• If you see a caliper over a flat shiny disc, it’s Disc—go to Step 3A.
• If you see a closed round housing (“can”), it’s Drum—skip to Step 3B.

Step 3A: (DISC) Remove the caliper and pads

• Turn the steering wheel is not needed—rear is fixed.
• Use a 14mm socket to remove the caliper slide bolts.
• Lift the caliper off and hang it using a bungee cord.
• Remove the pads and any pad clips/shims with a flathead screwdriver.

Step 4A: (DISC) Remove the caliper bracket

• Use a 17mm socket to remove the caliper bracket bolts.
• Set the bracket aside.

Step 5A: (DISC) Remove the rotor

• Pull the rotor straight off. If it’s stuck, tap the rotor hat with a rubber mallet.
• If it still won’t come off, the parking brake may be dragging—make sure it’s fully released.

Step 6A: (DISC) Prep and install the new rotor

• Spray the new rotor with brake parts cleaner to remove packing oil.
• Clean the hub face with a wire brush so the rotor sits flat. Flat hub = no pedal pulsation.
• Install the new rotor.

Step 7A: (DISC) Service the bracket and install new pads

• Clean bracket pad lands with a wire brush.
• Install new pad clips/shims (from the hardware kit).
• Apply a thin film of brake grease where pads slide in the clips (not on pad friction).
• Reinstall the bracket bolts using a 17mm socket, then Torque to 98 Nm (72 ft-lbs).

Step 8A: (DISC) Compress the caliper piston and reinstall caliper

• Remove the brake fluid reservoir cap under the hood (this helps the piston push back).
• Use a brake caliper piston compressor tool (specialty) (a tool that pushes the piston back evenly) or a C-clamp (6") to slowly press the piston in.
• Install the new pads.
• Reinstall the caliper using a 14mm socket, then Torque to 25 Nm (18 ft-lbs).

Step 3B: (DRUM) Remove the brake drum

• Pull the drum straight off.
• If it’s stuck, tap around the drum face with a rubber mallet.
• If it still won’t come off, the shoes may be catching on a ridge—use a drum brake adjuster spoon (specialty) through the backing plate access slot to back off the adjuster. (The adjuster is a star-wheel that spreads the shoes.)

Step 4B: (DRUM) Take a reference photo and remove springs/hardware

• Take a clear photo of the spring layout (left and right can differ).
• Use needle-nose pliers and a drum brake spring tool (specialty) (a hook tool for strong springs) to remove the return springs.
• Remove hold-down springs/pins and lift the shoes off.
• Remove the adjuster and note its orientation.

Step 5B: (DRUM) Clean and lightly lubricate contact points

• Spray the assembly with brake parts cleaner and wipe clean.
• Apply a tiny dab of brake grease to the backing plate “shoe pads” (the raised spots where shoes rub). Only on metal-to-metal contact points.

Step 6B: (DRUM) Install new shoes and hardware

• Install the new shoes using the new hold-down pins/springs from the hardware kit.
• Install the adjuster in the same orientation as removed.
• Use the drum brake spring tool (specialty) to reinstall the return springs.

Step 7B: (DRUM) Adjust shoes and install new drums

• Clean the new drums with brake parts cleaner.
• Slide the drum on. If it won’t fit, back off the adjuster with the adjuster spoon (specialty).
• Set adjustment so the drum turns with a very light, even drag (not tight).

Step 9: Reinstall wheels and torque lug nuts

• Reinstall wheels and hand-thread lug nuts.
• Lower the truck enough that tires touch the ground and won’t spin.
• Use a torque wrench and 21mm socket to tighten lug nuts in a star pattern: Torque to 133 Nm (98 ft-lbs).

✅ After Repair

• With the engine off, pump the brake pedal slowly 10–15 times until it feels firm. This seats the pads/shoes.
• Check brake fluid level and top off only if needed.
• Test at low speed first: forward and reverse, gentle braking.
• For new pads/rotors: do 6–8 medium stops from 35–10 mph, with cool-down time between stops (no panic stops).
• For drums: verify the parking brake holds after a short drive; if needed, re-adjust shoe drag slightly.
