Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Components

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set, then remove the wheel.
Inspect Brake Pads and Rotors:
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper and secure it with a bungee cord or rope to avoid strain on the brake line.
- Inspect the brake pads for uneven wear; replace if necessary.
- Check the rotor surface for scoring or warping; replace if damaged.
Caliper Inspection:
- Check for smooth operation of the caliper piston.
- Clean the caliper slide pins and apply fresh grease if necessary.
- Replace the caliper if it is found to be sticking or damaged.
Reassemble Brakes:
- Reinstall the caliper over the new or inspected brake pads.
- Tighten caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).
- Reinstall the wheel and torque lug nuts to the manufacturer’s specification (usually 90-100 ft-lbs).

3. Suspension Inspection

Visual Inspection:
- Check control arms, bushings, and tie rods for wear or damage.
- Look for signs of fluid leaks from any shocks or struts.
Replace any Damaged Components:
- If any suspension parts are worn, replace them following manufacturer guidelines.
- Ensure all nuts and bolts are torqued to specifications.
