Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Remove the master cylinder cap and check the brake fluid level. If low, top it off with the specified brake fluid type (usually DOT 3 or DOT 4).
Clean any dirt from the cap and surrounding area to prevent contamination when resealing.

3. Bleed Brake Lines

Tools Required: Brake bleeder kit or clear tubing, container to catch fluid, wrench.
Starting from the wheel farthest from the master cylinder (usually the right rear), attach the clear tubing to the bleeder valve.
Have an assistant press the brake pedal while you open the bleeder valve. Allow fluid and air to escape until a steady stream of fluid flows out.
Close the bleeder valve and repeat the process for each wheel in this order: right rear, left rear, right front, left front.
Monitor brake fluid level during the process and top off as necessary.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads, rotors (if needed).
Remove the wheel to access the brake assembly.
Inspect brake pads for thickness and rotors for scoring or warping. Replace if worn beyond specifications.
Clean rotor surfaces with brake cleaner if reusing. If replacing, ensure new rotors are installed according to manufacturer specifications and properly torqued.

5. Final Assembly

Reattach the wheel and lower the vehicle.
Ensure all tools are removed from the work area.
Test brake pedal feel before driving.
