Solution

1. Preparation

Tools Required: Brake fluid, socket set, wrench set, brake bleeder kit, jack and jack stands.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Fluid

Remove the master cylinder reservoir cap.
Check the brake fluid condition; if it appears dirty or contaminated, replace it.
Use a brake fluid siphon to remove old fluid and refill with fresh brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Inspect and Repair Brake Lines

Visually inspect all brake lines for signs of corrosion, leaks, or damage.
If any leaks are found, replace the affected brake line(s) using a line wrench to avoid rounding the fittings.
Ensure all connections are tight and recheck for leaks after repairs.

4. Bleed the Brake System

Attach a brake bleeder kit to the bleeder valve on the farthest brake caliper from the master cylinder (usually the right rear).
Open the bleeder valve and press the brake pedal slowly until the fluid is clear and free of bubbles.
Close the bleeder valve before releasing the brake pedal.
Repeat the process for all brake calipers in the following order: right rear, left rear, right front, left front.
Recheck the brake fluid level and top off as necessary.

5. Inspect and Replace Brake Components

Inspect the brake pads and rotors for wear. Replace if the pads are less than 3mm thick or if the rotors are warped.
Use a torque wrench to tighten new brake components to manufacturer specifications (usually around 25-30 ft-lbs for caliper bolts).
