Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and set the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Check and Refill Brake Fluid

Remove the cap from the master cylinder reservoir.
Inspect the brake fluid. If it is low, top it up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

3. Bleed the Brakes

Start with the brake farthest from the master cylinder (typically the rear passenger side).
Use a brake bleeder kit or a clear tube with a container.
Have an assistant press the brake pedal while you open the bleeder valve on the caliper.
Close the valve before your assistant releases the brake pedal.
Repeat until clear, bubble-free fluid flows from the bleeder.
Proceed to the other brakes in the order: rear driver, front passenger, and finally front driver.

4. Inspect and Replace Components if Necessary

If leaks were found, replace any damaged brake lines, calipers, or the master cylinder.
For worn brake pads, remove the caliper, replace the pads, and inspect rotors for damage. Resurface or replace as necessary.
Reassemble any components removed during inspection.

5. Final Assembly and Testing

Ensure all components are reassembled correctly and torqued to manufacturer specifications.
Test the brakes by pressing the pedal firmly to ensure a solid feel.
Lower the vehicle and perform a slow-speed test drive in a safe area to check braking performance.
