Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Components

Remove Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel using a socket set.
Examine Brake Pads and Rotors
- Inspect brake pads for thickness; replace if worn below 3mm.
- Check rotors for scoring or grooves; replace if necessary.
- Tools Required: Socket set, torque wrench.
Install New Brake Pads and Rotors (If Needed)
- Remove caliper bolts and carefully slide off the caliper.
- Replace pads and/or rotors.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 80-100 ft-lbs).

3. Inspect and Replace Wheel Bearings (If Needed)

Remove Brake Assembly
- Remove the brake caliper and bracket.
- Detach the rotor from the hub.
Check Wheel Bearings
- Spin the hub to listen for grinding; replace if rough or noisy.
- Tools Required: Bearing puller, press, torque wrench.
Reassemble Components
- Reinstall the rotor, brake assembly, and wheel.
- Torque all bolts to manufacturer specifications.

4. Inspect CV Joints and Axles (If Needed)

Visual Inspection
- Look for torn CV boots or grease leakage.
- Check for play in the axle.
Replace CV Joints or Axles (If Necessary)
