Step by Step: How to Replace Brake Discs and Brake Pads Yourself

Step by Step: How to Replace Brake Discs and Brake Pads Yourself

Introduction

Disc brakes are one of the most important components of a car’s braking system, responsible for safety and driving comfort. Regular replacement of brake discs and brake pads is crucial to ensure optimal braking performance. In this article, we present a detailed DIY guide that will show you step by step how to replace disc brake sets in your car.

Tools and Materials Needed for Replacement

Before starting the replacement of brake discs and brake pads, make sure you have all the necessary tools and materials:

  • A set of new brake discs and brake pads
  • Car jack and safety stands
  • Wheel wrench
  • Torque wrench
  • Socket wrench
  • Flathead screwdriver
  • C-clamp
  • Wire brush
  • Brake cleaner
  • Copper or ceramic grease
  • Protective gloves and safety glasses

Step 1: Preparing the Car

  1. Parking on a flat surface: Park the car on a level, stable surface and engage the handbrake.
  2. Removing the wheel: Loosen the wheel nuts before lifting the car. Use a car jack to lift the vehicle, then secure it on safety stands. Completely remove the wheel.

Step 2: Removing the Worn Brakes

  1. Removing the brake caliper: Use a socket wrench to loosen the caliper bolts. Gently remove the caliper and hang it on a hook or wire to avoid damaging the brake lines.
  2. Removing the brake pads: Remove the old brake pads from the caliper. You can use a flathead screwdriver to gently push them out.
  3. Removing the caliper bracket: Unscrew the caliper bracket bolts with a socket wrench. Remove the bracket to access the brake discs.
  4. Removing the brake disc: If the brake disc is bolted to the hub, unscrew the retaining bolts. If the disc is stuck, gently tap it with a hammer to loosen and remove it.

Step 3: Installing the New Brakes

  1. Cleaning the mounting surfaces: Use a wire brush and brake cleaner to thoroughly clean the mounting surfaces of the hub and caliper bracket.
  2. Installing the new brake disc: Mount the new brake disc on the hub and secure it with retaining bolts if provided.
  3. Installing the caliper bracket: Bolt the caliper bracket to the hub using a torque wrench to ensure the bolts are tightened to the correct specification.
  4. Installing the new brake pads: Apply a thin layer of copper or ceramic grease to the back of the new brake pads. Install the brake pads in the caliper bracket.
  5. Installing the brake caliper: Use the C-clamp to gently push the caliper piston back. Then, mount the caliper on the bracket and tighten the mounting bolts with a torque wrench.

Step 4: Mounting the Wheel and Testing

  1. Mounting the wheel: Place the wheel back on the hub and hand-tighten the wheel nuts.
  2. Lowering the car: Use the jack to gently lower the car to the ground. Tighten the wheel nuts with a torque wrench.
  3. Testing the brakes: Before driving, press the brake pedal several times to ensure the new brake discs and brake pads are properly seated and functioning correctly. Perform a short test drive, checking the braking effectiveness at low speeds.

Conclusion

Replacing brake discs and brake pads yourself may seem complicated, but with the right tools and instructions, it is a task that can be done at home. Remember to exercise caution and precision during the process to ensure maximum safety for yourself and other road users. With this DIY guide, you are one step closer to taking care of your car’s technical condition on your own.
