Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Tools Required: Jack and jack stands, socket set, brake fluid, turkey baster, wrench set.

2. Inspect and Replace Brake Fluid

Remove the master cylinder cap using a socket set.
Use a turkey baster to remove old brake fluid from the reservoir.
Refill the reservoir with new brake fluid according to the manufacturer’s specification (DOT 3 or DOT 4 as applicable).
Replace the master cylinder cap securely.

3. Inspect Brake Lines and Hoses

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect all brake lines and hoses for leaks, cracks, or corrosion.
If any damaged sections are found, replace them using the appropriate wrench size.

4. Bleed the Brakes

Starting at the farthest wheel from the master cylinder, attach a clear hose to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and old fluid, then close it before the assistant releases the pedal.
Repeat until no air bubbles are present, then move to the next wheel and repeat the process.
Ensure to top off the brake fluid after bleeding each wheel.

5. Inspect and Replace Brake Pads and Rotors (if necessary)

Remove the wheel and inspect the brake pads for wear.
If pads are below the minimum thickness (usually 3mm), replace them.
Inspect rotors for scoring or warping; replace if necessary.
Reassemble the brake components and wheel securely.
