Solution

1. Preparation

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

2. Inspect Brake Pads

Remove the wheel using a socket set.
Check for uneven wear on the brake pads; replace if worn below specifications (usually 3mm).
Tools Required: Socket set, brake pad gauge.

3. Check Brake Rotors

Inspect the brake rotor surface for warping (use a dial indicator if available).
If warped beyond standard tolerance (typically 0.002 inches), replace or resurface the rotors.
Tools Required: Dial indicator (if measuring), caliper tool for rotor replacement.

4. Examine Brake Calipers

Check for proper movement of the caliper pistons; make sure they retract fully.
Clean any rust or debris preventing movement and lubricate sliding pins if necessary.
Tools Required: Brake cleaner, grease for caliper pins.

5. Assess Wheel Bearings

With the wheel off, grab the rotor and check for any play or movement; replace bearings if worn.
Tools Required: Bearing puller set if replacing.

6. Verify Tire Condition

Inspect tires for uneven wear patterns, bulges, or low tread depth.
Balance tires if necessary and replace if damaged.
Tools Required: Tire pressure gauge, balancing machine (optional).
