Diagnostic Steps

1
Inspect the brake pads for uneven wear and thickness.
2
Check brake rotors for warping or scoring using a dial indicator.
3
Examine suspension components (control arms, bushings, etc.) for wear or damage.
4
Assess wheel alignment and tire balance.
5
Inspect brake calipers for proper operation and any sticking issues.

Solution

1. Preparation

Gather tools and parts: brake pads, rotors, socket set, jack, jack stands, torque wrench, and dial indicator.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it (do not let it hang by the brake line).
- Remove the old brake pads and check for uneven wear.
- Install new brake pads ensuring proper orientation and fit.
Brake Rotors:
- Inspect the rotor for warping using a dial indicator. If warped, replace it.
- Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor and secure it.

4. Reassemble and Lower Vehicle

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque settings.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque.

5. Final Checks

Inspect all components visually for proper installation.
Ensure no tools are left in the wheel well area.
