Step-by-Step Guide
Replacing brake discs is a relatively straightforward process, but it does require some mechanical aptitude and attention to detail. Here’s a step-by-step guide to help you replace your brake discs:
Step 1: Jack Up the Vehicle
1. Find a level surface and apply the parking brake.
2. Locate the jacking points on your vehicle (usually marked with a picture of a car and a jack).
3. Position the jack under the vehicle and raise it until the brake disc is accessible.
4. Use jack stands for added safety and stability.
Step 2: Remove the Wheel
1. Remove the lug nuts from the wheel using a socket wrench or ratchet and socket set.
2. Carefully pull the wheel straight off the hub and set it aside.
Step 3: Remove the Caliper
1. Locate the caliper, which is the metal housing that contains the brake pads.
2. Use a socket wrench or ratchet and socket set to loosen the caliper bolts.
3. Remove the caliper bolts and slide the caliper off the brake disc.
4. Use a wire or string to suspend the caliper from the suspension or a nearby anchor point to prevent it from falling and damaging the brake hose or other components.
Step 4: Remove the Old Brake Disc
1. Use a socket wrench or ratchet and socket set to loosen the brake disc retaining bolts.
2. Remove the retaining bolts and slide the brake disc off the hub.
3. Carefully pull the brake disc away from the hub and set it aside.
Step 5: Inspect and Clean the Hub
1. Inspect the hub for any debris, rust, or corrosion.
2. Clean the hub using a wire brush or cloth to remove any dirt or debris.
3. Apply a thin layer of brake grease to the hub to help prevent corrosion.
Step 6: Install the New Brake Disc
1. Place the new brake disc onto the hub, ensuring it is properly seated and aligned.
2. Use the brake disc retaining bolts to secure the brake disc to the hub.
3. Tighten the retaining bolts in a star pattern to ensure even pressure.
Step 7: Reinstall the Caliper
1. Slide the caliper back over the brake disc, ensuring it is properly seated and aligned.
2. Use the caliper bolts to secure the caliper to the brake disc.
3. Tighten the caliper bolts in a star pattern to ensure even pressure. (See Also: What Causes Brake Lights Not To Work)
Step 8: Reinstall the Wheel
