Introduction

This tutorial provides a step-by-step guide on how to replace the front brake pads and rotors on a 2018+ Jeep Wrangler JL or a 2020+ Jeep Gladiator JT. With the right tools and a bit of patience, you can perform this maintenance task at home, ensuring your vehicle remains safe and efficient on the road.

Step 1: Gather Required Tools

Before starting, ensure you have the following tools and materials ready:

• Mopar JL / JT Front Brake Pads
• Mopar JL / JT Front Brake Rotors
• Brake service kit
• Ratchet and socket set
• Torque wrench
• Brake cleaner
• Nitrex gloves (optional for cleanliness)

Step 2: Clean the Brakes

• Begin by cleaning the brake area to remove any dirt and debris. This prevents contamination during the replacement process.

Step 3: Remove Brake Master Cylinder Reservoir Cap

• Locate and carefully remove the cap from the brake master cylinder reservoir to relieve pressure before compressing the caliper pistons.

Step 4: Compress Caliper Pistons

• Use a caliper tool or a C-clamp to gently push back the caliper pistons. This creates enough space to accommodate the new, thicker brake pads.

Step 5: Remove Caliper

• Using the ratchet and correct socket, remove the bolts securing the caliper.
• Carefully slide the caliper off the rotor and hang it using a bungee cord or wire to avoid stress on the brake line.

Step 6: Remove Brake Pads and Slide Clips

• Take out the old brake pads from the caliper bracket.
• Remove any slide clips that may be attached.

Step 7: Remove Caliper Mounting Bracket

• Remove the bolts holding the caliper mounting bracket using the ratchet.
• Take off the bracket to access the rotor.

Step 8: Remove Rotor

• If necessary, remove any retaining screws or clips, then take off the old rotor from the hub.

Step 9: Install New Mopar Replacement Pads and Rotors

• Place the new rotor onto the hub, ensuring it sits flush. Secure it with the retaining screw, torquing it to 15 ft/lbs.

Step 10: Clean Rotors

• Use brake cleaner to wipe down the new rotors. This ensures they are free of oils or contaminants that could affect braking performance.

Step 11: Reinstall Caliper Mounting Bracket

• Reattach the caliper mounting bracket and torque the bolts to 148 ft/lbs.

Step 12: Install Pad Slide Clips

• Install new slide clips onto the caliper bracket to ensure proper fitment of the new brake pads.

Step 13: Lubricate and Install Brake Pads

• Apply brake lubricant to the edges of the new brake pads and slide them into place in the caliper bracket.

Step 14: Lubricate Slide Pins

• Remove and lubricate the caliper slide pins to ensure smooth movement.

Step 15: Reinstall Caliper

• Carefully slide the caliper back over the new pads and rotor.
• Torque the slide pin bolts to 27 ft/lbs.

Step 16: Repeat Steps for Passenger Side

• Follow the same steps for the passenger side brake pads and rotors.

Step 17: Reinstall Master Cylinder Reservoir Cap

• Once both sides are completed, replace the cap on the brake master cylinder reservoir.

Conclusion

Replacing the brake pads and rotors on your Jeep Wrangler JL or Gladiator JT can enhance your vehicle's braking performance and prolong its lifespan. Remember to regularly check your brakes and keep an eye on their condition. If you feel unsure at any stage, consult a professional mechanic for assistance. Happy driving!
