Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect all brake lines for signs of corrosion, wear, or damage.
2. If leaks are found, replace the affected brake line sections using the correct hydraulic brake line material.
3. Ensure all connections are tightened to the manufacturer’s specifications (typically around 15-25 Nm).

3. Brake Fluid Replacement

Sub-steps:
1. Remove the brake fluid reservoir cap and inspect the fluid for contamination.
2. Using a brake bleeder kit, siphon old brake fluid from the reservoir.
3. Refill the reservoir with new DOT 4 brake fluid to the maximum level.
4. Bleed the brake system starting from the furthest wheel to the closest to ensure no air remains in the system.

4. Inspect and Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness (should be above 3mm) and replace if worn.
3. Measure the rotor thickness and replace if below the minimum specification (usually 24mm for Skoda Octavia).
4. Install new pads and rotors, applying the recommended torque (usually 100-120 Nm for caliper bolts).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Reconnect the negative battery terminal.
3. Start the engine and pump the brake pedal several times to restore pressure.
4. Test drive the vehicle to ensure brakes feel firm and responsive.
