Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid siphon, new brake fluid (DOT 3 or 4 as specified by manufacturer)
Use a siphon to remove old brake fluid from the master cylinder reservoir.
Refill the reservoir with new brake fluid to the recommended level.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Attach the clear tubing to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and fluid; close the valve before the pedal is released.
Repeat this process until no air bubbles are observed in the fluid.
Repeat for all calipers, starting from the furthest from the master cylinder.

4. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads and/or rotors if needed
Remove the wheel to access the brake components.
Inspect brake pads for wear; replace if they are below the manufacturer's minimum thickness.
Check rotors for warping or damage; replace if necessary.
Clean calipers and other components with brake cleaner before reassembly.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery.
Test the brake pedal by pressing it firmly; it should feel firm and responsive.
