Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect the reservoir cap for proper sealing.

3. Identify and Repair Leaks

Visually inspect all brake lines and connections for any signs of leakage.
If a leak is found, replace the damaged brake line or component (e.g., brake hose, caliper).
Use a flare nut wrench to loosen and replace any corroded fittings.

4. Bleed Brake System

Start with the brake furthest from the master cylinder (usually the right rear wheel).
Attach a clear plastic tube 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, then hold it down.
Open the bleeder valve to release air and old fluid, then close it before the assistant releases the pedal.
Repeat the process until clear fluid is seen without bubbles, then move to the next wheel in order (left rear, right front, left front).

5. Test Brake Operation

After bleeding, check the brake pedal feel again.
Start the vehicle and perform a slow test stop in a safe area to ensure brakes are functioning properly.
