Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, refill with the appropriate brake fluid type (DOT 3 or DOT 4 as specified).
Replace the cap securely.

3. Inspect and Repair Brake Lines

Visually inspect all brake lines for any signs of corrosion or damage.
If leaks are found, replace the damaged sections of the brake line using a brake line repair kit.
Bleed the brake system after repairs to remove air bubbles.

4. Replace Brake Pads (if necessary)

Lift the vehicle and remove the wheels using a socket set.
Remove the caliper bolts and carefully slide the caliper off the brake pads.
Replace old brake pads with new ones, ensuring they are properly seated.
Reattach the caliper and torque the bolts to manufacturer specifications.

5. Test Brake Booster and Master Cylinder

Start the engine and press the brake pedal a few times; if the pedal remains soft, the brake booster may be faulty.
Inspect the master cylinder for leakage or fluid contamination; replace if necessary.
