Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is on a level surface and secure with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Brake Pad Inspection and Replacement

Tools Needed: Socket set, torque wrench, brake cleaner, and replacement brake pads.
Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Remove caliper bolts and carefully slide the caliper off the rotor.
3. Remove old brake pads from the caliper bracket.
4. Clean the caliper bracket with brake cleaner.
5. Install new brake pads, ensuring proper orientation.
6. Reattach the caliper and torque bolts to manufacturer specifications (typically around 20-30 ft-lbs).

3. Rotor Inspection and Resurfacing/Replacement

Tools Needed: Torque wrench, rotor puller (if necessary), and replacement rotors (if warped).
Sub-steps:
1. Measure rotor thickness and inspect for warping using a runout gauge.
2. If rotors are within specifications, they may be resurfaced; otherwise, replace them.
3. If replacing, remove the old rotor by unbolting it from the hub.
4. Install the new rotor and torque bolts to manufacturer specifications.

4. Suspension Component Inspection

Tools Needed: Jack and jack stands, socket set, and pry bar.
Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Visually inspect control arms, bushings, and tie rods for wear or damage.
3. Use a pry bar to check for play in bushings and joints.
4. Replace any worn or damaged components as necessary.

5. Wheel Alignment and Balancing

Tools Needed: Alignment tools (if doing in-house) or take the vehicle to an alignment shop.
Sub-steps:
1. If performing alignment, adjust camber, caster, and toe to manufacturer specifications.
2. Balance all four wheels to ensure even tire wear and handling.
