Measure pad thickness on both sides using a caliper.
3
Check brake rotor condition for warping or scoring.
4
Examine caliper operation for sticking or binding.
5

Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Clean Brake Components

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it with a bungee cord or similar tool (do not let it hang by the brake line).
Inspect the brake pads for uneven wear and replace if necessary.
Clean the brake rotor with brake cleaner and inspect for warping or scoring. Replace if damaged.

4. Address Root Causes

Caliper Inspection: Check caliper slides for lubrication. If they are stuck or corroded, clean and lubricate with high-temperature brake grease.
Suspension Check: Inspect control arms, ball joints, and bushings for wear. Replace any damaged components to ensure proper alignment.
Brake System Maintenance: Replace brake fluid if it is contaminated. Bleed the brake system to ensure proper hydraulic function.

5. Reassemble and Install Wheel

Reattach the caliper, ensuring it is properly seated and bolts are torqued to manufacturer specifications (typically around 24-30 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and fully tighten lug nuts in a crisscross pattern.
