Solution

1. Preparation

Gather all tools and parts needed.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner, C-clamp.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; if worn below 3mm, replace them.
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and install new brake pads, ensuring they are properly seated.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, dial indicator.
Check rotor thickness and flatness using a dial indicator.
- If warped beyond manufacturer specifications (typically more than 0.002 inches), replace the rotors.
- Remove the caliper bracket and then the rotor.
- Install new rotors, ensuring they are clean (use brake cleaner).
- Reattach the caliper bracket and tighten bolts to manufacturer specifications (usually around 85-100 ft-lbs).

4. Check and Replace Wheel Bearings (if necessary)

Tools Required: Socket set, bearing puller.
Remove the wheel and brake assembly to access the hub.
Inspect the wheel bearings for play or wear; replace if necessary.
- Remove the hub assembly using a bearing puller.
- Install new bearings and reassemble the hub.

5. Inspect and Repair Suspension Components

Check control arms, bushings, and ball joints for any signs of wear.
Replace any worn components as needed.
