Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean rag
Locate the master cylinder reservoir.
If the fluid is low, clean the area around the cap to prevent contamination.
Remove the cap and add the appropriate brake fluid (check owner's manual for specifications).
Replace the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench for bleeder screws, container for old fluid
Start with the wheel farthest from the master cylinder (typically the right rear).
Have an assistant pump the brake pedal several times and hold it down.
Loosen the bleeder screw on the brake caliper with a wrench while your assistant keeps the pedal down.
Allow old fluid and air to escape until a steady stream of fluid flows out, then tighten the bleeder screw.
Repeat the process on the next farthest wheel (left rear, then right front, then left front).
Check and refill the master cylinder reservoir as needed during the bleeding process.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake caliper.
Inspect brake pads for wear; replace if they are below the minimum thickness.
Inspect rotors for warping or scoring; replace if necessary.
Reassemble components and torque bolts to manufacturer specifications.
