Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels to access the brake components.

3. Inspect Brake Components

Brake Pads: Measure the thickness of each pad. Replace any that are below the manufacturer's minimum thickness.
Brake Rotors: Check for warping using a dial indicator or by visual inspection. Replace if warped or excessively worn.
Calipers: Check for proper movement. Clean and lubricate the caliper slides if they are sticking.

4. Address Uneven Wear Causes

Caliper Replacement: If calipers are found to be defective, replace them with OEM or quality aftermarket parts.
Brake Pad Replacement: Install new brake pads that match the specifications for your CR-V.
Rotor Replacement: If rotors are warped, replace them with new rotors ensuring they meet OEM standards.
Alignment and Suspension Repair: If misalignment is identified, have a professional alignment performed. Replace any worn suspension components.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Pump the brake pedal to ensure proper pad seating before driving.
