Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear appropriate safety gear (gloves and goggles).

2. Inspect and Replace Brake Pads and Rotors

Tools Required: Socket set, torque wrench, brake cleaner, jack stands.
Lift the vehicle using the jack and secure it with jack stands.
Remove the wheel to access the brake components.
Inspect the brake pads for uneven wear; replace if more than 50% worn or uneven.
Check the rotor surface for scoring or warping; replace if necessary.
Sub-steps for Replacement:
- Remove caliper bolts and slide the caliper off the rotor.
- Remove old brake pads and replace with new pads.
- If rotors are being replaced, remove the rotor by unscrewing retaining screws if applicable.
- Install new rotor, ensuring it is aligned properly.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).

3. Check and Replace Brake Calipers (if necessary)

Inspect calipers for signs of corrosion or fluid leaks.
If calipers are sticking, replace them with new units.
Sub-steps for Caliper Replacement:
- Disconnect the brake line from the caliper (use a container to catch any leaking fluid).
- Remove the caliper from its mounting bracket.
- Install the new caliper and connect the brake line.
- Bleed the brake lines to remove any air.

4. Inspect and Replace Suspension Components (if necessary)

Tools Required: Socket set, torque wrench, ball joint separator.
Check control arms and bushings for wear.
Replace any worn or damaged components.
Sub-steps for Replacement:
- Remove the wheel and access the control arm.
- Disconnect any attached components (e.g., sway bar links).
- Remove the control arm bolts and replace with new components.
- Torque bolts to manufacturer specifications.
