How to Replace Brake Pads and Rotors (COMPLETE Guide)

Introduction

This tutorial will guide you through the process of replacing brake pads and rotors on your car. Whether you're a beginner or just need a refresher, this complete step-by-step guide will help you perform this task safely and effectively, saving you money and boosting your confidence in car maintenance.

Step 1: Prepare Your Tools and Vehicle

• Gather the following tools:
  • Socket set
  • Breaker bar
  • Torque wrench
  • Metal wire brush
  • Brake piston compressor
  • Large hammer
  • Pry bar or flathead screwdriver
  • Jack and jack stands
• Collect consumables:
  • Copper anti-seize
  • Silicone paste
  • Brake cleaner
  • Thread locker
  • New brake pads (ceramic recommended) and rotors

Safety First

• Use wheel chocks to prevent the vehicle from rolling.
• Ensure the car is on a flat surface and engage the parking brake.

Step 2: Lift the Vehicle and Remove the Wheel

• Lift the front end of the car using a jack.
• Place jack stands securely under the vehicle's frame for support.
• Loosen the lug nuts while the vehicle is still on the ground; then, remove the wheel once it is lifted.

Step 3: Remove Old Brake Pads and Rotor

• Access the brake caliper by turning the steering wheel for better visibility.
• Remove the caliper bolt (usually a T50 torx) using a breaker bar. Then use a ratchet to completely remove it.
• Pry the caliper away gently and remove the old brake pads.
• If needed, remove the caliper bracket by unscrewing its bolts (typically 15mm).
• If the rotor is stuck due to rust, use a hammer to tap around the edge and break it free.

Step 4: Prepare the Hub and Install New Rotor

• Clean the hub surface using a wire brush or sandpaper to remove rust.
• Spray brake cleaner on the hub surface to ensure it’s clean.
• Install the new rotor by threading a lug nut to hold it in place while you work.

Step 5: Install Caliper Bracket and New Brake Pads

• Reattach the caliper bracket and tighten its bolts using a torque wrench (typically to 90 lb-ft).
• Compress the brake caliper piston using the brake piston compressor tool with an old brake pad.
• Install new brake hardware if applicable and slide in the new brake pads.

Step 6: Lubricate and Reattach the Caliper

• Apply copper anti-seize to key areas such as the caliper bracket and brake pad backing.
• Ensure the caliper guide pins are clean and lubricated with silicone paste.
• Reattach the caliper over the new brake pads and secure it with the caliper bolt, adding thread locker as needed. Torque to 25 lb-ft.

Step 7: Reinstall Wheel and Lower Vehicle

• Remove the lug nut used to hold the rotor in place.
• Place the wheel back on and hand-tighten the lug nuts.
• Lower the vehicle so that the tires just touch the ground to prevent spinning while torquing.
• Torque the lug nuts in a star pattern to 80-100 lb-ft (100 lb-ft recommended).

Step 8: Test the Brakes

• Start the vehicle and pump the brake pedal several times until it feels firm. This will restore brake pressure.
• Ensure everything is functioning properly before driving.
