🔧 IS - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake calipers, replace the pads and rotors, then torque everything correctly and bed-in the new pads. This restores braking performance and prevents vibration or pulsing caused by worn pads or warped rotors.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

Assumption: torque specs below are best-effort; verify with OEM data if available.

⚠️ Safety & Precautions

• Work on level ground and support the car with jack stands before going underneath.
• Do not breathe brake dust; use brake cleaner and wear a dust mask.
• Brakes may be hot; let the front brakes cool before you start.
• Never let the brake caliper hang by the rubber hose; support it with a bungee cord.
• Keep brake fluid off paint; wipe spills immediately.
• No battery disconnect is required for this front brake job.

📋 Before You Begin

• Park on level ground, turn the car off, and place wheel chocks behind the rear wheels.
• Loosen the front lug nuts slightly before lifting the car (use a 21mm socket and breaker bar).
• Open the hood and locate the brake fluid reservoir. Keep the cap set loosely on top (this helps when pushing the pistons back).
• Turn the steering wheel to give yourself more room at the caliper you’re working on.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front of the car

• Use a floor jack (rated 3-ton minimum) to lift the front of the car at the proper front jack point.
• Set the car onto jack stands (rated 3-ton minimum) and gently rock the car to confirm it’s stable.
• Remove the front wheels using a 21mm socket and ratchet.

Step 2: Remove the brake caliper

• The brake caliper is the clamp that squeezes the pads onto the rotor.
• Use a 14mm socket and ratchet to remove the two caliper slide-pin bolts.
• Lift the caliper off the pads and rotor, then hang it from the suspension spring using a bungee cord.

Step 3: Remove the pads and hardware

• Pull the old pads out by hand. If they’re stuck, use a flathead screwdriver gently to pry at the pad ears.
• Remove the pad clips/shims from the caliper bracket (set aside if reusing, but replacing is best).
• Use brake cleaner spray and shop towels to clean loose dust from the area.

Step 4: Remove the caliper bracket

• The caliper bracket is the metal mount that holds the pads and the caliper.
• Use a 17mm socket and breaker bar (1/2") to remove the two bracket bolts.
• Remove the bracket and set it on a clean surface.
• Torque spec (install): Torque to 105 Nm (77 ft-lbs)

Step 5: Remove the old rotor

• Pull the rotor straight off the hub.
• If it’s stuck from rust, spray the hub/rotor hat area with brake cleaner spray, then tap the rotor hat with a rubber mallet until it loosens.
• Use a wire brush to clean rust off the hub face so the new rotor sits perfectly flat.
• Clean hub = less brake vibration.

Step 6: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray and wipe with shop towels (this removes shipping oil).
• Slide the new rotor onto the hub.
• To keep it from wobbling while you work, thread on one lug nut by hand (use the old lug nut and only finger-tight).

Step 7: Reinstall the caliper bracket and hardware clips

• Reinstall the bracket over the new rotor using a 17mm socket and ratchet.
• Tighten with a torque wrench (1/2", 20-200 ft-lbs range).
• Torque to 105 Nm (77 ft-lbs)
• Install the new pad hardware clips into the bracket.
• Apply a thin film of brake caliper grease (silicone) where the pad ears slide on the clips.

Step 8: Compress the caliper piston

• The piston is the round push-piece inside the caliper that moves the pads.
• Place an old pad against the piston face, then use a C-clamp (6") to slowly press the piston back in.
• Go slowly and watch the brake fluid reservoir so it doesn’t overflow.
• Slow compression protects seals.

Step 9: Install the new pads and reinstall the caliper

• Install the new inner and outer pads into the bracket.
• Apply a small amount of brake caliper grease (silicone) to the pad backing plate contact points (where the caliper touches). Do not get grease on pad friction material or rotor.
• Remove the lug nut you used to hold the rotor (by hand).
• Set the caliper over the new pads and start the slide-pin bolts by hand.
• Tighten the slide-pin bolts using a 14mm socket and torque wrench (3/8", 10-80 ft-lbs range).
• Torque to 34 Nm (25 ft-lbs)

Step 10: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread all lug nuts.
• Lower the car off the stands using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a torque wrench (1/2", 20-200 ft-lbs range).
• Torque to 103 Nm (76 ft-lbs)

✅ After Repair

• Before starting the engine, pump the brake pedal 10-15 times until it feels firm (this seats the pads against the rotors).
• Check the brake fluid level and top off with DOT 3 only if needed.
• Test brakes at low speed in a safe area. Confirm no pulling, grinding, or warning lights.
• Pad bedding (recommended): make 6-10 moderate stops from 35 mph to 10 mph, with 30-60 seconds between stops. Avoid hard stops for the first 200 miles.
• Recheck lug nut torque after 25-50 miles using a torque wrench (1/2").
