🔧 Gladiator - Front Brake Pad Replacement

You’ll remove the front wheels, unbolt and hang the front calipers, swap the pads (and the pad clips), then compress the caliper pistons so everything fits with the thicker new pads. Doing the steps in order and torquing bolts correctly helps prevent noise, uneven wear, and brake pulsation.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• 🛑 Use jack stands; never rely on a floor jack alone.
• 🛑 Wear safety glasses and nitrile gloves; brake dust is harmful—use brake cleaner, not compressed air.
• 🛑 Do not press the brake pedal while the caliper is off the rotor.
• 🛑 Do not let the caliper hang by the brake hose; always support it.
• 🛑 No battery disconnect is required for this repair on your Gladiator.

📋 Before You Begin

• Park on level ground, shift to 1st gear, and set the parking brake.
• Chock the rear wheels with wheel chocks.
• Crack the front lug nuts loose 1/4 turn using a 21mm lug nut socket and 1/2" drive breaker bar.
• Open the hood and loosen the brake fluid reservoir cap (leave it sitting on top). This helps when you push the pistons back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front and remove the wheels

• Lift the front using a floor jack (rated 3-ton minimum).
• Place the frame securely on jack stands (rated 3-ton minimum).
• Remove the lug nuts using a 21mm lug nut socket and remove both front wheels.

Step 2: Turn the steering for access

• Turn the steering wheel so you can see the back side of the caliper bolts (it opens up space for your hands/tools).
• Spray the caliper/bracket area with brake cleaner spray if it’s dusty or muddy.

Step 3: Remove the caliper bolts

• Hold the slide pin (the smooth guide pin) using a T55 Torx bit socket.
• Remove the caliper bolts using a 13mm socket with a ratchet (3/8" drive).

Step 4: Remove and support the caliper

• Lift the caliper off the rotor. If it’s tight, gently pry with a flat blade screwdriver.
• Hang the caliper from the coil spring/frame using a brake caliper hanger hook.

Step 5: Remove old pads and the pad clips

• Pull the inner and outer pads out by hand.
• Remove the stainless pad clips from the bracket using a flat blade screwdriver.
• Clean the pad “rails” (the metal ledges the pads slide on) with a wire brush and brake cleaner spray.
• Clean rails prevent squeaks and sticking.

Step 6: Lube the slide pins and install new clips

• Remove each slide pin and wipe it clean.
• Apply a thin coat of brake caliper slide pin grease (silicone) and reinstall the pins.
• Install the new pad clips from the front brake pad hardware kit into the bracket by hand.

Step 7: Install the new pads

• Install the new inner and outer pads into the bracket.
• Confirm both pads can slide a little in the clips (they should not be jammed).

Step 8: Compress the caliper pistons

• Place an old pad against the piston, then compress the piston slowly using a C-clamp (6") until the piston is fully seated.
• Keep an eye on the reservoir so it doesn’t overflow.
• Slow compression helps protect the seals.

Step 9: Reinstall the caliper and torque bolts

• Set the caliper over the new pads and align the bolt holes.
• Install the caliper bolts using a 13mm socket while holding the slide pin with a T55 Torx bit socket.
• Tighten the caliper bolts to: Torque to 35 Nm (26 ft-lbs).

Step 10: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread lug nuts.
• Snug lug nuts using a 21mm lug nut socket.
• Lower the truck and torque lug nuts in a star pattern using a 1/2" drive torque wrench (30-250 ft-lbs).
• Tighten lug nuts to: Torque to 176 Nm (130 ft-lbs).

✅ After Repair

• Pump the brake pedal with the engine off until it feels firm.
• Check brake fluid level and reinstall/tighten the reservoir cap.
• Start the engine and verify the pedal feels normal, not spongy.
• Do a cautious road test: low speed first, then normal braking.
• Bed-in pads: 6-10 moderate stops from 30-40 mph with short cool-downs between stops.
