🔧 XT5 - Front Brake Pad Replacement
You’ll remove the front wheels, swing the front brake calipers up/off, swap the old pads for new ones, and compress the caliper pistons so everything fits back together. This restores safe stopping power and prevents metal-to-metal rotor damage when pads are worn.
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours
⚠️ Safety & Precautions
- 🛑 Support your XT5 with jack stands before working under/around the wheels.
- 🛑 Do not press the brake pedal while a caliper is removed.
- 🛑 Brake parts can be hot; let them cool before starting.
- 🛑 Avoid breathing brake dust; use brake cleaner, not compressed air.
- 🛑 Keep grease off pad/rotor friction surfaces.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks

📋 Before You Begin
- 🧱 Park on level ground, shift to P, and set the parking brake.
- 🧱 Place wheel chocks behind the rear tires.
- 🧱 Loosen the front wheel lug nuts 1/2 turn using a 19mm socket and breaker bar before lifting.
- 🧱 Open the hood and locate the brake fluid reservoir. Fluid may rise when compressing pistons.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift and remove the front wheels
- Lift the front with a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
- Remove lug nuts using a 19mm socket and 3/8" ratchet or breaker bar.
Step 2: Locate the caliper and pads
- Turn the steering wheel to give yourself room (left for right side work, right for left side work).
- Identify the front brake caliper (the clamp over the rotor) and the caliper bracket behind it.
Step 3: Remove the caliper slide pin bolts
- Remove the two caliper slide pin bolts using a 13mm socket and 3/8" ratchet.
- Lift the caliper off the bracket. If it’s tight, gently pry with a flat-blade screwdriver.
- Hang the caliper from the suspension using a bungee cord or mechanic’s wire. Never let it hang by the hose.
- Reinstall/torque later: Torque to 38 Nm (28 ft-lbs).
Step 4: Remove the old pads and hardware clips
- Slide the old inner and outer pads out by hand.
- Remove the stainless hardware clips from the caliper bracket.
- Clean the bracket pad “lands” (where clips sit) using a small wire brush and brake parts cleaner.
Step 5: Compress the caliper piston
- Place an old pad against the piston face, then slowly compress the piston using a C-clamp or brake caliper piston compressor (specialty).
- Check the brake fluid reservoir while compressing; remove excess if it gets too high using shop towels. Compress slowly to avoid overflow.
Step 6: Install new hardware clips and lubricate correctly
- Install new hardware clips onto the bracket by hand.
- Apply a thin film of silicone brake lubricant where the pad ears contact the clips.
- Do not lubricate the pad friction material or rotor face.
Step 7: Install the new pads
- Install the new inner and outer pads into the bracket.
- If one pad has a wear indicator/squealer, install it in the same position as the original on that wheel.
Step 8: Reinstall the caliper
- Lower the caliper over the new pads.
- Install the slide pin bolts using a 13mm socket and 3/8" ratchet.
- Final tighten with a 3/8" torque wrench (5-60 Nm range): Torque to 38 Nm (28 ft-lbs).
Step 9: Repeat on the other front wheel
- Repeat Steps 2–8 on the other side.
- Do one side at a time to avoid mixing parts.
Step 10: Reinstall wheels and torque lug nuts
- Reinstall wheels and hand-thread lug nuts.
- Lower your XT5 to the ground.
- Torque lug nuts in a star pattern using a 1/2" torque wrench (40-200 Nm range): Torque to 190 Nm (140 ft-lbs).
✅ After Repair
- 🧪 Before driving, pump the brake pedal 10–15 times until it feels firm.
- 🧪 Check the brake fluid level and top off only if needed.
- 🧪 Do a slow test drive and confirm no pulling, grinding, or warning lights.
- 🧪 Pad bed-in (break-in): make 8–10 moderate stops from 30–35 mph, letting brakes cool a bit between stops.
- 🧪 Recheck lug nut torque after 25–50 miles using a 1/2" torque wrench (40-200 Nm range): Torque to 190 Nm (140 ft-lbs).
