2
Check brake pads for uneven wear and thickness.
3
Examine suspension components (tie rods, control arms) for play or damage.
4
Inspect wheel alignment and tire balance.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Loosen the lug nuts slightly using a socket set while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the wheel completely to access the brake components.

3. Inspect and Replace Brake Rotors (if warped)

Tools Required: Torque wrench, rotor puller.
Measure the rotor thickness with a micrometer. If below minimum specifications or warped, proceed to replace.
Remove caliper bolts using a socket set and carefully hang the caliper without stressing the brake line.
Remove the old rotor by unbolting it or using a rotor puller if necessary.
Install the new rotor, ensuring it is properly seated.

4. Inspect and Replace Brake Pads

Remove the brake pads from the caliper bracket.
Inspect the pads for uneven wear; replace if necessary.
Clean the caliper bracket and apply anti-squeal lubrication on the backing plates of the new pads.
Reinstall the brake pads in the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to the specified value.
