🔧 Pacifica - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, swap the front brake pads, and replace the front rotors. New rotors are recommended anytime pads are replaced if the old rotors are worn, rusty, pulsating, or below thickness.

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

⚠️ Safety & Precautions

• ⚠️ Park on level ground and use jack stands—never rely on a jack alone.
• ⚠️ Keep the van OFF and not in READY mode; keep the key fob at least 10+ feet away so it can’t wake up.
• ⚠️ Brake dust is harmful—use brake cleaner, not compressed air.
• ⚠️ Don’t let the brake caliper hang by the hose—support it with a hanger.
• ⚠️ Watch brake fluid level when pushing the piston back; it can overflow.

📋 Before You Begin

• Park on a flat surface, shift to Park, and apply the parking brake.
• Chock the rear wheels with wheel chocks.
• Open the hood and check the brake fluid reservoir level; if it’s near MAX, remove a little with a clean towel (don’t spill). Prevent overflow when compressing pistons.
• Set your tools and new parts out; spray new rotors with brake cleaner and wipe dry to remove packing oil.
• A “caliper hook” is just a strong hook/strap used to hold the caliper so the hose isn’t stretched.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and lift the front

• Use a 21mm socket and breaker bar to loosen the front lug nuts 1/2 turn (do not remove yet).
• Lift the front with a floor jack at the approved front lift point and place jack stands under solid frame/approved support points.
• Remove the lug nuts with a 21mm socket and take the wheel off.

Step 2: Remove the caliper

• Turn the steering wheel to give yourself room (left side: wheel turned right; right side: wheel turned left).
• Use a 13mm socket (some use 14mm socket) and ratchet to remove the two caliper slide pin bolts.
• Lift the caliper off the bracket and hang it with a bungee cord or caliper hook (specialty).

Step 3: Remove old pads and inspect

• Remove the brake pads from the bracket by hand (use a small flathead screwdriver gently if they’re stuck).
• Check the rubber slide pin boots for tears and check pins for rust or sticking.

Step 4: Remove the caliper bracket

• Use an 18mm socket (some use 21mm socket) with a breaker bar to remove the two caliper bracket bolts from the knuckle.
• Set the bracket aside.
• When reinstalling later: Torque to 169 Nm (125 ft-lbs).

Step 5: Remove the rotor

• If equipped with a rotor retaining screw, remove it using a Torx T30 bit and ratchet.
• Pull the rotor straight off. If it’s stuck, tap the rotor hat area firmly (not the studs) and/or clean rust from the hub with a wire brush.

Step 6: Clean the hub and install the new rotor

• Use a wire brush to clean rust from the hub face (where the rotor sits).
• Spray the new rotor with brake cleaner spray and wipe with shop towels.
• Install the new rotor. If there’s a retaining screw, install it with Torx T30 bit and ratchet, then Torque to 13 Nm (115 in-lbs).

Step 7: Service bracket hardware and slide pins

• Remove old pad hardware clips from the bracket (use a small flathead screwdriver).
• Clean the bracket pad “lands” with a wire brush so the new clips sit flat.
• Install new hardware clips from the front brake hardware kit.
• Pull slide pins out one at a time, wipe clean with shop towels, apply a thin coat of brake caliper slide pin grease, and reinstall.

Step 8: Reinstall bracket

• Position the bracket over the rotor and start both bracket bolts by hand.
• Use an 18mm socket (or 21mm socket) and ratchet to snug them.
• Finish with a torque wrench: Torque to 169 Nm (125 ft-lbs).
• Hand-start bolts to avoid cross-threading.

Step 9: Compress the caliper piston

• Place the old inner pad against the piston face.
• Use a C-clamp (6" minimum) to slowly push the piston fully back into the caliper.
• Check the brake fluid reservoir as you compress; stop if it nears overflowing.

Step 10: Install new pads and reinstall caliper

• Install the new pads into the bracket (make sure they slide freely in the clips).
• Place the caliper over the new pads.
• Install the caliper slide pin bolts using a 13mm socket (or 14mm socket) and ratchet.
• Finish with a torque wrench: Torque to 35 Nm (26 ft-lbs).

Step 11: Reinstall the wheel

• Put the wheel back on and hand-thread all lug nuts.
• Lower the van off the jack stands with the floor jack.
• Use a torque wrench and 21mm socket to tighten lug nuts in a star pattern: Torque to 135 Nm (100 ft-lbs).

Step 12: Repeat on the other front wheel

• Do the exact same steps on the other side.
• Always replace pads and rotors in pairs.

✅ After Repair

• With the van still OFF, press the brake pedal slowly 8–12 times until it feels firm (this seats the pistons).
• Check brake fluid level and top off only if needed with the correct fluid type listed on the reservoir cap.
• Start the van and do a cautious test at low speed; confirm no pulling, grinding, or warning lights.
• Bed-in (break in) the pads: do 6–10 moderate stops from 30–40 mph, allowing a little cooling between stops; avoid hard panic stops for the first 200 miles.
• Recheck lug nut torque after 25–50 miles with a torque wrench.
