Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

Using a jack, lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check for warping using a dial indicator gauge.
If warped, remove the rotors by unscrewing the caliper bracket bolts and sliding the rotor off the hub.

B. Replace or Resurface Rotors

If the rotors are excessively worn or warped, replace them with new ones.
If they are only slightly warped, consider resurfacing them according to manufacturer specifications.

C. Inspect Brake Pads

Remove brake caliper using a socket set and hang it securely to avoid strain on the brake line.
Inspect the pads for wear; replace them if they are below the manufacturer’s minimum thickness.

4. Reassemble

Reinstall the brake caliper over the new or resurfaced rotor and new pads.
Tighten caliper bolts to manufacturer torque specifications (usually around 25-30 ft-lbs).
Reinstall the wheels and lower the vehicle.

5. Wheel Alignment Check

After repairs, perform a wheel alignment to ensure proper handling and tire wear.
