🔧 Mustang - Front Brake Pad Replacement

You’ll be removing the front wheels, sliding the front brake calipers out of the way, and swapping the old pads for new ones. This restores safe stopping power and prevents rotor damage when pads get too thin.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• ⚠️ Support the car with jack stands—never rely on a jack alone.
• ⚠️ Brakes may be hot; let everything cool before touching.
• ⚠️ Do not press the brake pedal with a caliper removed.
• ⚠️ Brake fluid can damage paint; wipe spills immediately.
• ⚠️ If brake fluid is near “MAX,” siphon a little out before compressing pistons.

📋 Before You Begin

• Park on a level surface, put the shifter in P, and set the parking brake.
• Place wheel chocks behind both rear tires.
• Loosen the front lug nuts slightly before lifting (do not remove yet).
• Open the hood and locate the brake fluid reservoir; keep the cap sitting on top (not fully tightened) so fluid can move as you compress pistons.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front and remove the wheels

• Use a 21mm socket and breaker bar to loosen lug nuts 1/2 turn.
• Lift the front with a floor jack (rated 3-ton minimum), then support with jack stands (rated 3-ton minimum).
• Remove lug nuts with the 21mm socket and take off both front wheels.

Step 2: Remove the caliper slide bolts

• Turn the steering wheel to give yourself room (left for right side, right for left side).
• On the back of the caliper, remove the two slide bolts using a 7mm hex bit socket and ratchet (3/8" drive).
• If the slide pin spins, hold it carefully with a 13mm socket while loosening the 7mm hex.
• Slide bolts are the “small” caliper bolts.

Step 3: Lift the caliper off and support it

• Use a small flathead screwdriver to gently pry the caliper outward a little (this creates clearance).
• Lift the caliper off the bracket and pads.
• Hang the caliper from the suspension using a bungee cord (do not let it hang by the brake hose).

Step 4: Remove old pads and hardware

• Pull the inner and outer pads out by hand.
• Remove the stainless pad clips from the bracket (if equipped) using the small flathead screwdriver.
• Clean the bracket pad “lands” (where clips sit) with a wire brush and brake parts cleaner spray.
• Clean metal helps pads slide smoothly.

Step 5: Compress the caliper piston

• Position the old inner pad against the piston face.
• Use a caliper piston compressor tool (specialty) to slowly press the piston back into the caliper until fully seated.
• A piston compressor is a clamp that pushes the piston in.
• Check the brake fluid reservoir while compressing; do not let it overflow.

Step 6: Install new hardware clips and pads

• Install new stainless clips from the hardware kit into the bracket by hand (press until fully seated).
• Apply a very thin film of brake caliper grease (silicone-based) to the clip contact points (where the pad ears touch). Avoid the pad friction material and rotor.
• Install the new inner and outer pads into the bracket.

Step 7: Reinstall the caliper and tighten bolts

• Slide the caliper over the new pads.
• Install the slide bolts by hand first, then tighten with the 7mm hex bit socket and torque wrench.
• Torque to 35 Nm (26 ft-lbs) for the front caliper slide bolts.

Step 8: Reinstall wheels and torque lug nuts

• Reinstall wheels and thread lug nuts by hand.
• Lower the car off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a torque wrench.
• Torque to 203 Nm (150 ft-lbs) for the lug nuts.

Step 9: Restore pedal feel

• With the car on the ground, press the brake pedal slowly 8–12 times until it feels firm.
• Check brake fluid level and top off only if needed.

✅ After Repair

• Start your Mustang and hold the brake pedal; confirm it stays firm and doesn’t sink.
• Do a slow test roll in a safe area and confirm normal stopping.
• If you installed new pads on used rotors, expect light noise for the first few stops.
• Pad bedding (recommended): make 6–10 moderate stops from ~40 mph down to ~10 mph with cool-down time between; avoid hard stops while stationary right after.
• Recheck for fluid leaks and recheck lug nut torque after 25–50 miles.
