Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and turn off the engine.
Disconnect the battery for safety.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect the brake pads for even wear; replace if uneven.
- Check the rotors for warping or scoring; replace if necessary.
Replace Brake Pads (if worn):
- Remove caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Replace the old pads with new ones, ensuring they are correctly positioned.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).

3. Brake Fluid and Caliper Check

Check Brake Fluid:
- Inspect the brake fluid reservoir and top off with the recommended DOT fluid if low.
Inspect Calipers:
- Ensure calipers are not sticking and are functioning properly.
- If calipers are faulty, replace them following the manufacturer's guidelines.

4. Suspension and Alignment Inspection

Inspect Suspension Components:
- Check control arms, bushings, and tie rods for wear.
- Replace any damaged components.
Perform Wheel Alignment:
- Take the vehicle to an alignment shop for precise adjustment.
