Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safely lift the vehicle using jack stands if necessary.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake line flare tool, brake cleaner, rags.
Inspect all brake lines and connections for leaks. If a leak is found, replace the damaged section of the line or tighten connections.
Clean the area with brake cleaner to remove any spilled fluid.

3. Replace Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4 as specified), funnel, turkey baster.
Use a turkey baster to remove old brake fluid from the master cylinder reservoir.
Fill the reservoir with fresh brake fluid up to the designated level.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container for old fluid.
Connect clear tubing to the bleeder valve on the farthest brake caliper from the master cylinder.
Open the bleeder valve and pump the brake pedal until no air bubbles are present in the tubing.
Close the valve, and repeat for each brake caliper in order (farthest to nearest).
Monitor fluid levels in the master cylinder and top off as needed during the process.

5. Inspect and Replace Brake Components (if necessary)

If brake pads or calipers are worn, replace them.
Tools Required: Socket set, brake caliper tool.
Remove the wheel, unbolt the caliper, and replace pads or caliper as needed.
Reassemble and torque bolts to manufacturer specifications.
