Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, clean funnel, rags
Check the brake fluid for contamination. If dirty, proceed to replace.
Using the clean funnel, siphon out old brake fluid from the reservoir.
Refill the reservoir with new brake fluid according to the manufacturer’s specifications (DOT 3 or DOT 4).

3. Inspect Brake Lines and Components

Tools Required: Wrench set, socket set, flashlight
Visually inspect all brake lines for leaks or damage, focusing on connections and junctions.
If leaks are found, replace the affected brake line or component.
Check brake calipers for signs of leaking brake fluid; replace if necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Start at the furthest wheel from the master cylinder (usually the right rear).
Attach the tubing to the bleeder valve and submerge the other end in a container with brake fluid.
Open the bleeder valve and have an assistant press the brake pedal several times, then hold it down.
Close the bleeder valve before releasing the pedal. Repeat until no air bubbles appear in the tubing.
Move to the next wheel and repeat the process until all four brakes are bled.

5. Final Checks and Reassembly

Recheck brake fluid level in the reservoir and top off if necessary.
Inspect all connections and ensure everything is secure.
Reconnect the battery.
