Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Put on safety gloves and goggles for protection.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid master cylinder.
Remove the cap and check the fluid level, looking for any signs of contamination.
If fluid is low, top it off with the manufacturer's recommended brake fluid type.

3. Examine Brake Lines and Hoses

Starting from the master cylinder, follow the brake lines towards the wheels.
Look for any signs of leakage or corrosion on the lines.
Inspect the rubber brake hoses at each wheel for cracks, bulges, or leaks.
If any line or hose shows damage, proceed to replace it.

4. Check Brake Calipers and Wheel Cylinders

Remove the wheel on each side to access the brake calipers and wheel cylinders.
Inspect the calipers for fluid leakage around the seals and piston.
For drum brakes, inspect the wheel cylinders for leaks as well.
If leakage is detected, replace the faulty caliper or wheel cylinder.

5. Clean and Test

Clean any spilled brake fluid from the areas inspected with brake cleaner.
Re-check the brake fluid level after repairs.
Reinstall wheels and lower the vehicle.

6. Final Check

Pump the brake pedal to ensure it feels firm.
Test drive the vehicle at low speeds to confirm proper brake function.
