Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Pads and Rotors

Remove Wheel
- Use a lug wrench to loosen the lug nuts before lifting the vehicle with a jack.
- Secure the vehicle on jack stands and remove the wheel completely.
Inspect Brake Components
- Examine brake pads for thickness; they should be at least 3mm thick. Replace if worn.
- Check rotors for scoring or warping by using a straight edge. Replace if warped beyond manufacturer specifications.
Replace Brake Pads
- Remove caliper bolts with a socket wrench and carefully slide the caliper off the rotor.
- Remove the old brake pads and install new pads, ensuring they are properly seated.
Replace Brake Rotors
- Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, aligning it with any retaining features.
Reassemble
- Reattach the caliper over the new pads and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).
- Reinstall the wheel and tighten lug nuts in a star pattern to the specified torque (typically 80-100 ft-lbs).

3. Wheel Alignment and Balancing

Check Tire Pressure
- Ensure all tires are inflated to the manufacturer’s recommended pressure.
Alignment Check
- Use an alignment machine or take the vehicle to a professional for proper alignment adjustments.
Balance Tires
- Have the tires balanced if there are signs of uneven wear or vibration at speed.
