Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake cleaner, rags.
Locate any leaks in the brake lines or around the calipers.
If a leak is found, tighten any loose connections or replace damaged hoses or calipers as necessary.
Clean any brake fluid spills with brake cleaner.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench for bleeder screws, container for old brake fluid.
Start at the wheel farthest from the master cylinder (usually the right rear).
Open the bleeder screw slightly with a wrench and have an assistant press the brake pedal down.
Close the bleeder screw before the pedal reaches the floor.
Repeat this process until no air bubbles are visible in the fluid coming from the bleeder.
Move to the next wheel (left rear, then right front, and finally left front), repeating the process at each wheel.

4. Replace Brake Fluid

Parts Required: New brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
After bleeding, top off the master cylinder with new brake fluid.
Check the brake fluid level after several depressions of the brake pedal and add fluid as necessary.

5. Final Inspection

Recheck all connections and ensure that there are no leaks.
Test the brake pedal feel; it should be firm and responsive.
