đź”§ XT5 - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake calipers, replace the pads and rotors, then reassemble and torque everything to spec. This restores braking performance and fixes pulsation/vibration caused by worn pads or warped rotors.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours


⚠️ Safety & Precautions

  • ⚠️ Work on level ground and support the XT5 with jack stands—never rely on a jack.
  • ⚠️ Brakes create dust—wear a mask and use brake cleaner, not compressed air.
  • ⚠️ Do not let the caliper hang by the brake hose; support it with a hook/strap.
  • ⚠️ Brake fluid can damage paint; wipe spills immediately.
  • ⚠️ Battery disconnect is not required for front brake/rotor replacement.

đź”§ Required Tools

You'll need the following tools for this repair:

  • Floor jack (rated 3-ton minimum)
  • Jack stands (rated 3-ton minimum, pair)
  • Wheel chocks
  • 19mm socket
  • 1/2" drive breaker bar
  • 1/2" drive torque wrench (30-200 ft-lbs range)
  • 15mm socket
  • 18mm socket
  • Ratchet (3/8" or 1/2")
  • Caliper piston compressor tool (specialty)
  • Bungee cord or caliper hook
  • Wire brush
  • Rubber mallet
  • Small flathead screwdriver
  • Safety glasses
  • Nitrile gloves

đź“‹ Before You Begin

  • Park on level ground, shift to Park, and set the parking brake.
  • Chock the rear wheels with wheel chocks.
  • Turn the steering wheel to give yourself room (left for right side work, right for left side work).
  • Open the hood and locate the brake fluid reservoir so you can monitor the fluid level while compressing pistons.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and raise the front

  • Use a 19mm socket and breaker bar to loosen the front lug nuts 1/2 turn (don’t remove yet).
  • Lift the front with a floor jack (rated 3-ton minimum) and set it securely on jack stands (rated 3-ton minimum, pair).
  • Remove the lug nuts with the 19mm socket and remove the front wheels.

Step 2: Remove the front brake caliper

  • Turn the steering to expose the caliper you’re working on.
  • Use a 15mm socket and ratchet to remove the two caliper guide pin bolts.
  • Lift the caliper off the bracket and support it using a bungee cord or caliper hook.
  • Never let the caliper hang by the hose.

Step 3: Remove the pads and inspect

  • Remove the inner and outer pads by hand. If they’re stuck, gently pry with a small flathead screwdriver.
  • Check the rubber boots around the slide pins for tears and check for uneven wear (a clue of sticking pins).

Step 4: Remove the caliper bracket

  • The caliper bracket is the metal mount the caliper bolts to; it must come off to remove the rotor.
  • Use an 18mm socket and breaker bar to remove the two caliper bracket bolts.
  • Set the bracket aside.
  • When reinstalling later: Torque to 170 Nm (125 ft-lbs).

Step 5: Remove the rotor and clean the hub

  • Pull the rotor straight off. If it’s stuck, tap around the hat area with a rubber mallet.
  • Use a wire brush to clean rust from the hub face (where the rotor sits).
  • Spray the hub and surrounding area with brake cleaner (use nitrile gloves and safety glasses).

Step 6: Install the new rotor

  • Spray both sides of the new rotor with brake cleaner to remove protective oil, then wipe clean.
  • Install the rotor onto the hub.
  • To keep the rotor from flopping while you work, thread on one lug nut by hand (use the 19mm socket only lightly if needed).

Step 7: Service the bracket hardware and reinstall the bracket

  • Remove the old pad clips from the bracket using a small flathead screwdriver.
  • Clean the clip seating areas with a wire brush, then install the new hardware clips by hand.
  • Reinstall the bracket and tighten the bolts with an 18mm socket and torque wrench: Torque to 170 Nm (125 ft-lbs).

Step 8: Compress the caliper piston

  • Check the brake fluid reservoir level under the hood—fluid may rise as you compress the piston.
  • Use a caliper piston compressor tool (specialty) to press the piston straight back into the caliper until fully seated.
  • Press slowly to avoid damaging seals.

Step 9: Install new pads and reinstall the caliper

  • Apply a thin layer of high-temp silicone brake lubricant to pad ears where they contact the clips (do not get lube on pad friction material or rotor).
  • Install the new inner and outer pads into the bracket by hand.
  • Place the caliper over the new pads.
  • Reinstall the caliper guide pin bolts using a 15mm socket, then tighten with a torque wrench: Torque to 30 Nm (22 ft-lbs).

Step 10: Reinstall wheels and torque lug nuts

  • Reinstall the wheels and hand-thread all lug nuts.
  • Lower the XT5 off the jack stands using the floor jack.
  • Tighten lug nuts in a star pattern using a torque wrench: Torque to 190 Nm (140 ft-lbs).

âś… After Repair

  • Before starting the engine, press the brake pedal 8–12 times until it feels firm (this seats the pistons).
  • Check brake fluid level; top off with DOT 3 brake fluid only if needed.
  • Test at low speed first. Confirm no pulling, grinding, or warning lights.
  • Pad bedding (recommended): make 8–10 moderate stops from 30–40 mph with cool-down driving between stops. Avoid hard stops for the first 200 miles.
