Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles for protection.

2. Inspect and Top Off Brake Fluid

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Close the master cylinder cap securely.

3. Identify and Repair Leaks

Inspect brake lines, calipers, and hoses for any signs of leakage.
If leaks are found, replace the damaged components.
- Tools: Wrenches, brake line tool
- Parts: Brake lines, calipers, or hoses as needed

4. Replace Brake Pads and Rotors (if necessary)

Remove the wheel to access the brake assembly.
Remove the brake caliper by loosening the caliper bolts and sliding it off the rotor.
Remove the old brake pads and inspect the rotor for wear.
Replace with new brake pads and, if needed, replace the rotor.
- Tools: Socket set, brake pad spreader
- Parts: New brake pads, potentially new rotors

5. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the rear passenger side).
Attach a clear hose to the bleeder valve on the brake caliper and submerge the other end in a container with brake fluid.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal.
Repeat this process at each wheel until no air bubbles are visible in the fluid.
