Tools You'll Need:
* Jack and jack stands: Essential for safely lifting the vehicle. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Socket wrench set: Including the appropriate sizes for your caliper bolts and wheel lug nuts.
* C-clamp or brake caliper compression tool: To compress the caliper piston.
* Wrench or socket for caliper bracket bolts (if applicable): Some models require removing the caliper bracket.
* Penetrating lubricant (like PB Blaster): To help loosen rusted or seized bolts.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
* New brake pads: Make sure you get the correct pads for your specific Wrangler model and year.
* Torque wrench: To tighten bolts to the correct specification.
* Wire brush or sandpaper: To clean the caliper mounting surface.
General Steps (May vary slightly depending on your Wrangler model):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels opposite the one you're working on.
2. Lift and Secure: Lift the vehicle using the jack and securely place it on jack stands.
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Expose the Caliper: You should now see the brake caliper and brake pads.
5. Compress the Caliper Piston: Use the C-clamp or compression tool to push the caliper piston back into the caliper. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal. Some pistons rotate as they're compressed.
6. Remove the Old Brake Pads: Depending on your model, you may need to remove caliper bracket bolts or just unclip the brake pads. The old pads should slide out relatively easily. Inspect the caliper slides and clean them if necessary. Lightly lubricate them with high-temperature brake caliper grease.
7. Install the New Brake Pads: Insert the new brake pads into their respective slots.
8. Reinstall the Caliper: Reinstall the caliper over the new brake pads. Ensure that the caliper bolts are tightened to the manufacturer's specified torque.
9. Reinstall the Wheel: Replace the wheel and tighten the lug nuts in a star pattern to the manufacturer's specified torque.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Test the Brakes: Before driving, pump the brake pedal several times to ensure the brakes are working correctly. Test the brakes gently at low speeds before driving at normal speeds.
Important Considerations:
* Brake fluid: While this procedure doesn't directly involve brake fluid, it's a good idea to check your brake fluid level before and after the job. Low brake fluid can indicate a leak.
* Rotor condition: Inspect your brake rotors for wear and tear. If they're excessively worn, grooved, or warped, they should be replaced or resurfaced.
* Caliper Condition: If you notice any signs of damage or sticking on the caliper itself, you may need to replace or rebuild it.
This is a simplified guide. Refer to your owner's manual or a reputable online repair guide specific to your Jeep Wrangler year and model for detailed, accurate instructions. If you're unsure about any step, seek professional help. Incorrectly installed brakes can be extremely dangerous.
