Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent any electrical hazards.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner, jack stands, lug wrench.
Sub-steps:
1. Lift the rear of the vehicle using a floor jack and secure it with jack stands.
2. Remove the rear wheels using a lug wrench.
3. Inspect the brake pads for wear. If they are less than 3mm thick, replace them.
4. Remove the caliper mounting bolts with a socket set.
5. Carefully slide the caliper off the rotor and support it without damaging the brake line.
6. Remove the old pads and install new ones, ensuring they are properly seated.
7. Reinstall the caliper and secure it with the mounting bolts, tightening to the manufacturer's specified torque.

3. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if rusted), torque wrench.
Sub-steps:
1. If the rotors are worn or warped, remove them by unscrewing the retaining screws.
2. Clean the hub surface with brake cleaner to remove any debris.
3. Install new rotors, ensuring they are seated correctly.
4. Tighten retaining screws to the specified torque.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing.
Sub-steps:
1. Refill the brake fluid reservoir with fresh brake fluid.
2. Start bleeding from the farthest wheel from the master cylinder (right rear, left rear).
3. Attach the clear tubing to the bleeder valve on the brake caliper.
4. Open the valve and have an assistant press the brake pedal until fluid flows steadily through the tubing.
5. Close the valve and repeat until no air bubbles are present.
6. Repeat the process for the left rear caliper and check the fluid level frequently.

5. Reassemble and Test

Sub-steps:
1. Reinstall the rear wheels and lower the vehicle.
2. Reconnect the negative battery terminal.
3. Start the vehicle and press the brake pedal a few times to ensure proper engagement.
4. Test drive the vehicle to ensure brakes are functioning correctly.
