Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Inspect and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the reservoir cap seal. Replace if worn.

3. Bleed the Brake System

Start at the farthest wheel from the master cylinder (usually the right rear).
Attach a clear hose to the bleeder valve on the brake caliper and place the other end in a container.
Have an assistant pump the brake pedal several times and then hold it down.
Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal.
Repeat until no air bubbles appear in the fluid.
Move to the next wheel (left rear, right front, left front) and repeat the process.

4. Inspect and Replace Components (if necessary)

If issues persist, inspect the master cylinder for signs of failure or leaks.
Remove the master cylinder from the brake booster by disconnecting the brake lines and mounting bolts.
Replace with a new master cylinder if leaking or malfunctioning.
Reattach the brake lines and bleed the brakes again.

5. Final Assembly and Inspection

Recheck fluid levels in the reservoir after bleeding.
Inspect all brake lines and connections for tightness and leaks.
Replace any damaged or worn components found during inspection.
