Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electronic brake components.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and securely place it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad replacement kit (includes new pads), brake cleaner, C-clamp.
Sub-steps:
1. Remove the caliper bolts using a socket.
2. Carefully slide the caliper off the rotor and support it without stressing the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper slides for corrosion and clean if necessary.
5. Compress the caliper piston using a C-clamp to make room for new pads.
6. Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench, rotor removal tool (if needed).
Sub-steps:
1. Check the rotor surface for grooves or warping.
2. If damaged, remove the rotor by unscrewing the retaining screws or using a rotor puller.
3. Install new rotors, ensuring they are properly seated.
4. Torque the rotor screws to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the brake caliper over the new pads and secure it with bolts.
2. Reattach the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to manufacturer specifications.
4. Reconnect the battery if it was disconnected.
5. Pump the brake pedal to seat the new pads and check brake fluid level.
