Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use jack stands to elevate the vehicle safely.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake rotor for warping using a dial indicator. If warped beyond specification, proceed to replace.
3. Remove caliper bolts with a socket, then carefully detach the brake caliper and support it without stressing the brake line.
4. Remove the brake rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
5. Install the new rotor, ensuring it is seated properly and reattach any retaining screws.
6. Reinstall the brake caliper and torque bolts to manufacturer specifications (typically around 25-35 Nm).
7. Reattach the wheel and torque lug nuts to manufacturer specifications (usually 100-120 Nm).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Inspect the pads for wear; replace if they are below the manufacturer's minimum thickness (generally less than 3mm).
3. Lubricate the caliper slide pins and contact points with high-temperature brake grease.
4. Install new brake pads in the caliper bracket.

4. Suspension Component Inspection and Replacement (if necessary)

Sub-steps:
1. Inspect control arms, bushings, and tie rods for wear or damage.
2. If components are worn, remove and replace them using appropriate tools (wrenches and sockets).
3. Ensure all bolts are torqued to the specified values as per the manufacturer’s recommendations.
