🔧 86 - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake calipers, replace the pads and rotors, then reinstall everything with the correct torque. Doing this restores braking performance and helps prevent vibration or noise from worn rotors.

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

⚠️ Safety & Precautions

• 🛑 Support your 86 on jack stands—never rely on a floor jack alone.
• 🛑 Brake dust is hazardous—wear a dust mask and avoid blowing dust with compressed air.
• 🛑 Do not let the brake caliper hang by the hose—support it with a bungee cord.
• 🛑 Keep grease and brake fluid off pad/rotor friction surfaces; clean with brake cleaner if contaminated.
• 🛑 Do not press the brake pedal while a caliper is removed.

📋 Before You Begin

• Park on level ground, put the transmission in P, and set the parking brake.
• Chock the rear wheels using wheel chocks.
• Loosen the front lug nuts 1/2 turn using a 19mm socket and breaker bar before lifting.
• Open the hood and check the brake fluid level—when you compress the pistons, the fluid level can rise. Remove a little fluid if near MAX.
• If your 86 has factory Brembo front calipers (fixed caliper, pad pins/retainer), follow the steps labeled Brembo. Otherwise, use the Standard steps.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front and remove the wheels

• Lift the front of the car with a floor jack and set it securely on jack stands.
• Remove the lug nuts using a 19mm socket and ratchet, then remove both front wheels.

Step 2: Turn the steering for access

• Turn the steering wheel to give yourself more room at the side you’re working on (left for right side work, right for left side work).

Step 3 (Standard): Remove the front caliper and pads

• Locate the two caliper slide bolts on the back of the caliper.
• Remove the slide bolts using a 14mm socket and ratchet.
• Lift the caliper off the bracket and suspend it with a bungee cord.
• Remove the brake pads and the pad clips (hardware) with a flat-head screwdriver if needed.

Step 3 (Brembo): Remove the pads from the fixed caliper

• Remove the pad retaining pins and spring clip using a punch set and small hammer.
• Slide the pads out of the caliper.
• Take a quick photo first for reassembly.

Step 4: Remove the caliper bracket or caliper (to free the rotor)

• Standard: Remove the two caliper bracket bolts using a 17mm socket and breaker bar, then remove the bracket.
• Brembo: Remove the caliper mounting bolts using a 17mm socket and breaker bar, then suspend the caliper with a bungee cord.

Step 5: Remove the rotor

• Pull the rotor straight off the hub.
• If it’s stuck, thread two M8 x 1.25 bolts into the rotor’s extraction holes and tighten evenly with a ratchet until the rotor pops free.
• If needed, tap the rotor hat with a rubber mallet to break rust loose.

Step 6: Clean and prep the hub and new rotor

• Clean rust from the hub face using a wire brush. A clean hub helps prevent brake vibration.
• Spray the new rotor friction surfaces with brake parts cleaner spray and wipe with shop rags (removes shipping oil).

Step 7: Install the new rotor

• Place the new rotor onto the hub.
• To hold it in place while you work, thread on one lug nut by hand (use your original lug nut) and snug it lightly.

Step 8 (Standard): Reinstall the bracket, service hardware, and compress the piston

• Reinstall the caliper bracket and tighten the bracket bolts using a 17mm socket and torque wrench: Torque to 80 Nm (59 ft-lbs).
• Install new pad clips/hardware from your kit into the bracket.
• Apply a thin film of brake caliper grease to pad “ears” where they slide on the clips. Do not grease pad faces.
• Compress the caliper piston slowly using a C-clamp brake piston compressor until it bottoms in the bore.

Step 8 (Brembo): Compress pistons and reinstall the caliper

• Because Brembo calipers are fixed, you may have multiple pistons per caliper.
• Compress the pistons slowly and evenly using a C-clamp brake piston compressor (work side-to-side so they go in evenly).
• Reinstall the caliper over the new rotor, then tighten the caliper mounting bolts using a 17mm socket and torque wrench: Torque to 115 Nm (85 ft-lbs).

Step 9: Install new pads and reassemble the caliper

• Standard: Install the new pads into the bracket, then set the caliper over the pads.
• Install the caliper slide bolts using a 14mm socket and torque wrench: Torque to 27 Nm (20 ft-lbs).
• Brembo: Slide the new pads into place, reinstall the spring clip and pad pins using a punch set and small hammer until fully seated.

Step 10: Repeat on the other front wheel

• Repeat Steps 3–9 on the other side. Do one side at a time.

Step 11: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread all lug nuts.
• Lower the car to the ground.
• Tighten lug nuts in a star pattern using a 19mm socket and torque wrench: Torque to 120 Nm (89 ft-lbs).

Step 12: Restore brake pedal pressure

• With the engine OFF, pump the brake pedal slowly 10–15 times until it feels firm.
• Check brake fluid level and top off with DOT 3 brake fluid if needed.

✅ After Repair

• Start the engine and confirm the brake pedal stays firm.
• Do a slow test in a safe area: confirm no pulling, grinding, or warning lights.
• Bed-in (break-in) the pads/rotors: make 8–10 moderate stops from ~40 mph down to ~10 mph, driving a bit between stops to cool, then avoid hard stops for the first 150–200 miles.
• Recheck lug nut torque after 25–50 miles: Torque to 120 Nm (89 ft-lbs).
