🔧 Express 3500 - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake caliper and bracket, replace the rotor, then install new pads and reassemble with the correct torque. New rotors and pads restore stopping power, reduce vibration/pulsation, and protect your calipers from overheating.

Difficulty Level: Intermediate | Estimated Time: 2.0-3.5 hours

Assumption: stock front brakes (no aftermarket big-brake kit).

⚠️ Safety & Precautions

• 🛑 Support your van with jack stands on the frame; never rely on a jack alone.
• 🛑 Do not press the brake pedal with the caliper removed (the piston can pop out).
• 🛑 Brakes can contain harmful dust—use brake cleaner, not compressed air.
• 🛑 Hang the caliper with a hook/bungee; don’t let it dangle by the rubber brake hose.
• 🛑 Brake fluid can overflow when compressing pistons—check the master cylinder level first.

📋 Before You Begin

• Park on level ground, shift to PARK, set the parking brake, and chock the rear wheels.
• Pop the hood and locate the brake fluid reservoir; if it’s near “MAX,” remove a little with a clean syringe/turkey baster so it won’t overflow when you compress the pistons.
• Loosen the front lug nuts 1/2 turn while the wheels are still on the ground (use a breaker bar).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Use a floor jack to lift the front at a safe lift point on the frame.
• Set the van onto jack stands under the frame and give it a firm shake test.
• Remove lug nuts with a 21mm socket and take off both front wheels.

Step 2: Remove the caliper (the part that squeezes the pads)

• Turn the steering to give yourself room to work (use the steering wheel by hand).
• Use a flat blade screwdriver to gently pry the caliper outward a little (this helps clear the old pads).
• Remove the caliper slide pin bolts using your caliper slide pin bolt socket.
• Lift the caliper off the bracket and hang it with a mechanic’s hook or bungee cord.

Step 3: Remove the brake pads and hardware clips

• Pull the old pads out of the bracket by hand.
• Remove the stainless hardware clips from the bracket using a flat blade screwdriver.
• Use brake cleaner spray and a brake parts cleaning brush to clean the bracket pad “rails” (where the clips sit).

Step 4: Remove the caliper bracket

• Remove the two large caliper bracket bolts using a breaker bar 1/2" and 21mm socket.
• Set the bracket aside.

Step 5: Remove the rotor

• Pull the rotor straight off the hub by hand.
• If it’s stuck from rust, spray around the center hub area with brake cleaner, then tap the rotor “hat” area with a dead-blow hammer until it breaks free.
• Use a wire brush to clean rust off the hub face (this helps prevent brake pulsation).

Step 6: Install the new rotor

• Clean the new rotor thoroughly with brake cleaner spray (this removes protective shipping oil).
• Slide the new rotor onto the hub.
• Tip: hold rotor with one lug nut hand-tight.

Step 7: Service the caliper bracket and slide pins

• Pull the slide pins out of the bracket by hand (they’re the smooth pins the caliper “floats” on).
• Wipe the pins clean and apply a thin coat of high-temp silicone brake grease.
• Reinstall the slide pins and confirm they move smoothly.
• Install the new hardware clips onto the bracket (press them in by hand).

Step 8: Reinstall the caliper bracket

• Position the bracket over the new rotor.
• Apply medium-strength threadlocker (blue) to the bracket bolt threads.
• Tighten the bracket bolts using a torque wrench 1/2".
• Torque to 221 Nm (163 ft-lbs)

Step 9: Install the new pads

• Apply a very light smear of high-temp silicone brake grease to pad “ears” where they contact the hardware clips (do not get grease on pad friction material).
• Slide the new pads into the bracket until they sit squarely.

Step 10: Compress the caliper piston and reinstall the caliper

• Use a C-clamp 6" to slowly push the caliper piston back in (place an old pad against the piston face to spread the force).
• Tip: go slow; watch the brake fluid level.
• Set the caliper over the new pads.
• Install the slide pin bolts using your caliper slide pin bolt socket and tighten with a torque wrench 3/8".
• Torque to 31 Nm (23 ft-lbs)

Step 11: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-start all lug nuts.
• Lower the van to the ground using the floor jack.
• Tighten lug nuts in a star pattern using a torque wrench 1/2".
• Torque to 190 Nm (140 ft-lbs)

Step 12: Pump the brake pedal before moving

• With the engine OFF, press the brake pedal 10–15 times until it feels firm.
• Top off brake fluid with DOT 3 if needed (do not overfill).

✅ After Repair

• Start the engine and hold the brake pedal; confirm it stays firm and does not sink.
• Do a slow test in a safe area: verify normal stopping and no pulling, grinding, or clunking.
• Bed-in the pads (break-in): make 8–10 moderate stops from ~40 mph down to ~10 mph, with short cool-down rolls between stops; avoid hard panic stops for the first 200 miles.
• Recheck brake fluid level after the test drive and inspect for leaks around both calipers.
