Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues during repair.

2. Check Brake Fluid Level

Remove the master cylinder cap.
Inspect the brake fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4).
If fluid is low, check for leaks before proceeding.

3. Inspect Brake Components

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to access brake components.
Visually inspect brake lines, calipers, and wheel cylinders for leaks or damage.
Check brake pads for thickness and ensure they are not worn excessively.

4. Bleed the Brake System

Locate the bleeder valve on each brake caliper.
Start with the brake farthest from the master cylinder (usually the right rear).
Have an assistant press the brake pedal while you open the bleeder valve to release air; close the valve before the pedal is released.
Repeat until clear fluid without bubbles flows from the bleeder.
Move to the next brake in the order: left rear, right front, left front.
Ensure the master cylinder is topped off with brake fluid throughout the process.

5. Replace Brake Components (if necessary)

If any components are found to be damaged during inspection, replace them as needed.
For brake pads, compress the caliper piston using a brake caliper tool before installation.
Reassemble all components and wheels, ensuring all fasteners are torqued to manufacturer specifications.
