Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, brake cleaner, torque wrench, safety glasses, gloves.
Raise the vehicle securely on jack stands and remove the wheels to access the brake components.

2. Inspect and Clean Brake Components

Brake Pads: Remove the brake caliper by unscrewing the caliper bolts. Inspect the brake pads for wear; replace if they are worn down below the minimum thickness.
Calipers: Check the calipers for proper movement. Clean any debris or rust from the caliper slide pins and apply brake grease.
Rotors: Inspect the rotors for any signs of warping or scoring. If damaged, replace the rotors.

3. Check Brake Fluid and Lines

Inspect the brake fluid for contamination. If the fluid appears dirty or discolored, flush the brake system and replace with fresh brake fluid per manufacturer specifications.
Inspect the brake lines for leaks or bulges. Replace any damaged lines.

4. Reassemble and Test

Reinstall the brake components in reverse order. Ensure all bolts are torqued to manufacturer specifications.
Reinstall wheels and lower the vehicle. Pump the brake pedal to restore brake pressure.
