Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat, stable surface.
Disconnect the battery to prevent electrical issues.

2. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line flare tool
Inspect all brake lines for corrosion, damage, or leaks.
If any damage is found, replace the affected brake line(s):
- Use a wrench to disconnect the damaged line.
- Cut a new line to the appropriate length and flare the ends.
- Connect the new line and ensure all fittings are tight.

3. Replace Brake Fluid

Tools Required: Brake fluid, fluid siphon or turkey baster
Remove old brake fluid from the reservoir using a siphon.
Refill the reservoir with new brake fluid as specified in the owner's manual.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing
Start with the brake furthest from the master cylinder (usually the passenger rear wheel):
- Attach the tubing to the bleeder screw and submerge the other end in a container with brake fluid.
- Have an assistant pump the brake pedal several times and hold it down.
- Open the bleeder screw to release air and fluid, close the screw, and repeat until no air bubbles are visible.
Repeat for all brakes in the correct order (passenger rear, driver rear, passenger front, driver front).

5. Test the Brake System

Reconnect the battery.
Pump the brake pedal to ensure it feels firm.
Test drive the vehicle at low speeds to confirm proper brake function.
