🔧 Gladiator - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, swap the brake pads and rotors on both sides, then reassemble and bed-in the new pads. New rotors are important because worn or uneven rotors can cause vibration, noise, and longer stopping distances.

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

⚠️ Safety & Precautions

• Work on a flat, solid surface and support your Gladiator with jack stands before going under or removing wheels.
• Do not breathe brake dust; use brake cleaner and wear a dust mask.
• Never let the caliper hang by the brake hose—support it with a caliper hanger hook.
• Brake parts may be hot if you just drove; let them cool.
• No battery disconnect is required for a front brake/rotor job.

📋 Before You Begin

• Park on level ground, put the transmission in 1st gear, and set the parking brake.
• Place wheel chocks behind the rear tires.
• Crack the front lug nuts loose using a 21mm socket and a breaker bar (do not remove yet).
• Open the hood and remove the brake fluid reservoir cap (set it loosely on top). This helps when compressing caliper pistons.

🔨 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) at the front jacking point, then support the frame with jack stands (rated 3-ton minimum).
• Remove the lug nuts with a 21mm socket (1/2" drive) and take both front wheels off.

Step 2: Remove the caliper (do not disconnect the hose)

• Turn the steering so you can access the caliper bolts more easily. More room = less frustration.
• Remove the two caliper slide bolts using a 13mm socket (3/8" drive) and a 3/8" drive ratchet.
• Lift the caliper off the bracket and support it with a brake caliper hanger hook.

Step 3: Remove the old brake pads and hardware

• Pull the inner and outer pads out by hand (use a small flathead screwdriver gently if they’re stuck).
• Remove the old pad clips/hardware from the bracket using a small flathead screwdriver.
• Spray the bracket contact areas with brake cleaner spray and scrub with a wire brush.

Step 4: Remove the caliper bracket and rotor

• Remove the caliper bracket bolts using a 21mm socket (1/2" drive) and a 1/2" drive breaker bar.
• Remove the bracket and set it aside.
• Pull the rotor straight off. If it’s seized to the hub, tap the rotor hat with a rubber mallet to break it free.

Step 5: Prep the hub and install the new rotor

• Clean the hub face with a wire brush and brake cleaner spray. A clean hub helps prevent brake pulsation.
• Clean the new rotor surfaces with brake cleaner spray to remove protective oil.
• Install the new rotor onto the hub.

Step 6: Reinstall the caliper bracket (torque it)

• Reinstall the caliper bracket and start the bolts by hand.
• Tighten using a 21mm socket (1/2" drive) and torque with a torque wrench (10-250 ft-lbs range).
• Torque to 176 Nm (130 ft-lbs)

Step 7: Compress the caliper pistons

• Use a brake caliper piston compressor tool (specialty) to slowly push the pistons back until fully seated.
• Watch the brake fluid reservoir so it doesn’t overflow; remove excess fluid if needed (use a clean rag and go slowly).
• Go slow to avoid damaging seals.

Step 8: Install new pad hardware and pads

• Install the new pad clips/hardware onto the bracket.
• Apply a thin film of brake lubricant (silicone brake grease) where the pad “ears” slide on the clips (do not get grease on pad friction material or rotor).
• Install the new inner and outer pads into the bracket.

Step 9: Reinstall the caliper (torque it)

• Lower the caliper over the new pads.
• Install the caliper slide bolts using a 13mm socket (3/8" drive).
• Torque using a torque wrench (10-250 ft-lbs range).
• Torque to 35 Nm (26 ft-lbs)

Step 10: Repeat on the other front side

• Repeat Steps 2-9 on the other front wheel.
• Always do brakes in pairs.

Step 11: Reinstall wheels and torque lug nuts

• Reinstall both wheels and hand-start all lug nuts.
• Lower the truck off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
• Torque lug nuts in a star pattern using a 21mm socket (1/2" drive) and a torque wrench (10-250 ft-lbs range).
• Torque to 176 Nm (130 ft-lbs)

✅ After Repair

• Before starting the engine, pump the brake pedal 10-15 times until it feels firm. This seats the pads against the rotors.
• Check brake fluid level and reinstall the reservoir cap.
• Test at low speed first. Make sure it stops straight and there are no abnormal noises.
• Pad bed-in (recommended): do 6-10 moderate stops from ~40 mph down to ~10 mph, letting brakes cool slightly between stops. Avoid hard panic stops for the first 200 miles.
