🔧 XT4 - Front Brake Pad Replacement

Replacing the front brake pads restores safe stopping and prevents metal-to-metal damage to your rotors. On your XT4, you’ll remove the front caliper, swap pads/hardware, compress the caliper piston, then reassemble and bed-in the pads.

Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours

⚠️ Safety & Precautions

• 🛑 Support the XT4 with jack stands—never rely on a floor jack alone.
• 🛑 Do not press the brake pedal with a caliper removed (the piston can pop out).
• 🛑 Brakes and wheels can be hot; let them cool before starting.
• 🛑 Avoid breathing brake dust; use brake cleaner and wear a dust mask.
• 🛑 Keep brake fluid off paint; it can damage finishes.
• 🛑 Battery disconnect is not required for front pads.

📋 Before You Begin

• Park on level ground, turn the steering wheel straight, and set the parking brake.
• Place wheel chocks behind the rear tires.
• Loosen the front lug nuts slightly before lifting (don’t remove them yet).
• Open the hood and locate the brake fluid reservoir; check that it isn’t overfilled.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and raise the front

• Use a 22mm socket with a breaker bar to loosen the lug nuts about 1/2 turn.
• Lift the front with a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum) under safe lift points.
• Remove the wheel using the 22mm socket.

Step 2: Inspect the caliper and locate the wear sensor

• Turn the steering wheel to give yourself working room (left for right side, right for left side).
• If equipped, find the pad wear sensor wire at the caliper area and trace it to the connector.
• Use a flathead screwdriver to release any small retaining clips carefully.

Step 3: Remove the caliper guide pin bolts

• Use a 13mm socket and ratchet (3/8-inch drive) to remove the two caliper guide pin bolts.
• Lift the caliper off the bracket.
• Support the caliper with a brake caliper hanger hook (specialty) (this is a hook/strap that holds the caliper so the brake hose isn’t stretched).

Step 4: Remove old pads and hardware

• Slide the old pads out of the bracket by hand.
• Remove the stainless pad clips (hardware) from the bracket.
• Use brake cleaner spray and shop towels to clean the bracket pad-landing areas.
• Use a wire brush to remove rust where the clips sit. Clean metal helps pads slide smoothly.

Step 5: Compress the caliper piston

• Place an old pad against the piston face (to spread the force).
• Use a C-clamp (6-inch) to slowly push the piston back into the caliper.
• Check the brake fluid reservoir as you compress; remove a little fluid if it gets too full (use shop towels for spills).

Step 6: Install new hardware and pads

• Install the new stainless hardware clips into the bracket (they should snap fully into place).
• Apply a thin film of brake caliper grease (silicone) where the pad ears contact the clips (do not get grease on pad friction material or rotor).
• Install the new inner and outer pads into the bracket.
• If equipped, install the front brake pad wear sensor in the same position as the original and route the wire exactly like factory.

Step 7: Reinstall the caliper

• Set the caliper back over the new pads.
• Install the guide pin bolts by hand first to avoid cross-threading.
• Tighten using a 13mm socket and torque wrench: Torque to 35 Nm (26 ft-lbs).

Step 8: If you removed the caliper bracket (only if needed)

• If your pad/rotor service required bracket removal, reinstall the bracket bolts using an 18mm socket.
• Tighten using a torque wrench: Torque to 185 Nm (136 ft-lbs).

Step 9: Reinstall wheel and torque lug nuts

• Reinstall the wheel and hand-thread all lug nuts.
• Lower the XT4 until the tire just touches the ground and won’t spin.
• Use a 22mm socket and torque wrench to tighten lug nuts in a star pattern: Torque to 190 Nm (140 ft-lbs).

Step 10: Pump the brake pedal before driving

• With the engine off, press the brake pedal 8–12 times until it feels firm.
• This seats the pads against the rotors after the piston was pushed back.

✅ After Repair

• Check brake fluid level and top off only if needed (use the correct DOT rating listed on the reservoir cap).
• Start the engine and confirm the brake pedal feels normal and firm.
• Road test at low speed first; verify no pulling, grinding, or warning lights.
• Pad bed-in: make 6–10 moderate stops from 35–10 mph, allowing short cool-down between stops. Avoid hard panic stops at first.
• Recheck lug nut torque with a torque wrench after 25–50 miles.
