Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. If the fluid is low, top it off with the recommended brake fluid (DOT 4 for most Skoda models).
3. If the fluid appears dark or contaminated, proceed to flush the brake system.
Tools Required: Brake fluid, funnel, clean rags.

3. Check and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Unbolt the caliper and lift it away from the rotor.
3. Inspect the brake pads for wear (replace if less than 3mm thick).
4. Install new brake pads, ensuring they are properly aligned.
5. Reattach the caliper and torque bolts to manufacturer specifications (typically 25-35 Nm).
Tools Required: Socket set, torque wrench, brake pad spreader.

4. Inspect and Replace Brake Rotors

Sub-steps:
1. If rotors are scored or below minimum thickness (usually 24 mm for Skoda Octavia), they need replacing.
2. Remove the caliper and brackets to access the rotor.
3. Unbolt the rotor and replace it with a new one.
4. Reassemble caliper and brackets, torquing bolts to manufacturer specifications.
Tools Required: Torque wrench, socket set.

5. Test Brake Booster

Sub-steps:
1. With the engine off, pump the brake pedal until it feels firm.
2. Start the engine; the pedal should drop slightly indicating the booster is functioning.
Tools Required: None specific, just observation needed.
