Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir (typically near the driver’s side of the engine bay).
If the fluid is low, clean the area around the reservoir cap to prevent contamination, then remove the cap.
Use manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified) to refill to the appropriate level.
Replace the cap securely.

3. Bleed the Brake System

Begin at the wheel furthest from the master cylinder (usually the right rear).
Connect a clear plastic tube to the bleeder valve on the brake caliper and submerge the other end in a container.
Have an assistant press the brake pedal several times and hold it down.
Open the bleeder valve to allow air and old fluid to escape, then close it before the pedal is released.
Repeat this process until clear, bubble-free fluid flows out, and then tighten the bleeder valve.
Move to the next wheel (left rear, then right front, and finally left front) and repeat the procedure.
Check brake fluid level again after bleeding.

4. Inspect and Replace Brake Components (if necessary)

If the brake pads are worn down below the manufacturer’s specifications, replace them.
Inspect rotors for warping or damage; replace if they exceed thickness specifications.
Ensure all brake components are securely fastened and properly aligned.
