Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, wrench.
Locate the brake fluid reservoir and remove the cap.
Check the fluid level; if low, top off with the manufacturer-recommended brake fluid type.
Recheck for leaks around the reservoir and connection points.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, wrench, catch container.
Start from the wheel farthest from the master cylinder (usually the passenger side rear).
Have an assistant press the brake pedal several times and hold it down.
Open the bleeder valve on the brake caliper to allow air and fluid to escape, then close the valve.
Repeat this process until there are no more air bubbles in the fluid.
Move to the next wheel and repeat until all wheels are bled.

4. Inspect and Replace Components if Necessary

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads/rotors (if needed).
Remove the wheel to access the brake components.
Inspect brake pads for thickness; replace if worn down.
Check rotors for scoring or warping; replace if necessary.
Clean the brake components with brake cleaner before reassembly.

5. Reassemble and Test

Reinstall the wheel and torque down the lug nuts to manufacturer specifications.
Pump the brake pedal a few times to ensure proper firmness.
Test drive the vehicle to ensure brakes engage as expected.
