Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Brake Rotor Replacement

Sub-step 1: Remove the wheel by loosening the lug nuts with a socket wrench.
Sub-step 2: Remove the brake caliper by unbolting it from the bracket; hang it safely using a bungee cord.
Sub-step 3: Remove the old brake rotor. If it is rusted or stuck, gently tap with a rubber mallet.
Sub-step 4: Install the new rotor, ensuring it is properly seated against the hub.
Sub-step 5: Reattach the brake caliper over the new rotor and torque the caliper bolts to the manufacturer’s specifications (typically 25-35 ft-lbs).

3. Brake Pad Replacement

Sub-step 1: Remove the old brake pads from the caliper bracket.
Sub-step 2: Inspect the caliper bracket for damage and clean if necessary.
Sub-step 3: Install new brake pads, ensuring they are correctly oriented and secured.

4. Reassembly

Sub-step 1: Reinstall the wheel and hand-tighten the lug nuts.
Sub-step 2: Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 75-95 ft-lbs).
Sub-step 3: Reconnect the negative battery terminal.

5. Brake System Bleeding (if necessary)

Sub-step 1: If brake fluid was lost, bleed the brake system using a brake bleeder kit to remove any air.
Sub-step 2: Ensure the brake fluid reservoir is filled to the appropriate level with the specified fluid.
