Solution

1. Preparation

Tools Required: Socket set, jack, jack stands, torque wrench, OBD-II scanner, brake rotor gauge.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if necessary) to ensure safety.
Gather all tools and replacement parts.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using a socket set.
3. Inspect the brake rotors for warping using a rotor gauge. If warped beyond specifications, proceed to replace.
4. If replacement is needed, remove the brake caliper (use a torque wrench for caliper bolts) and hang it securely without stressing the brake line.
5. Remove the rotor from the hub. Clean the mounting surface to ensure a proper fit for the new rotor.
6. Install the new rotor and reattach the brake caliper.
7. Torque caliper bolts to manufacturer specifications.

3. Inspect and Replace Brake Pads

Sub-steps:
1. While the caliper is removed, check the brake pads for wear. Replace them if they are below the minimum thickness.
2. Remove the old brake pads from the caliper bracket.
3. Apply brake grease to the back of the new pads to prevent squeaking and install them.
4. Reassemble the caliper and ensure proper alignment.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and tie rods for any signs of damage or excessive play.
2. If any parts are found to be damaged, replace with OEM or equivalent parts.
3. Recheck all suspension components for proper installation.

5. Wheel Alignment and Balance

Sub-steps:
1. After replacing components, take the vehicle to a professional for wheel alignment.
2. Ensure that all wheels are balanced properly to prevent further shaking during braking.
