Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Open the hood and locate the master cylinder reservoir.
If the fluid is low, use DOT 3 or DOT 4 brake fluid to top it off to the recommended level.
Inspect the reservoir cap for proper sealing.

3. Inspect and Repair Leaks

Visually inspect all brake lines, hoses, and connections for any signs of leakage.
If leaks are found, replace damaged brake lines or fittings as necessary.
Tighten any loose connections and ensure all components are secure.

4. Bleed the Brake System

Connect a brake bleeder kit or use the two-person method to bleed the brakes.
Start with the wheel farthest from the master cylinder (usually the passenger rear).
Open the bleeder valve and have an assistant press the brake pedal until fluid flows without bubbles.
Close the bleeder valve and repeat for the other wheels in the following order: driver rear, passenger front, driver front.
Check fluid levels periodically during the bleeding process.

5. Replace Brake Components (if necessary)

If brake pads or rotors are excessively worn, replace them.
Remove the wheel, then remove caliper bolts to access the brake pads.
Replace brake pads and inspect rotors for damage or warping. Resurface or replace rotors as needed.
