2. If replacing, disconnect the hydraulic lines carefully to prevent fluid spillage.
3. Install new master/slave cylinders and reconnect the hydraulic lines securely.
4. Bleed the clutch system to eliminate air bubbles by having an assistant press the clutch pedal while you open the bleeder valve.

4. Clutch Assembly Inspection

Tools Required: Transmission jack, socket set, torque wrench.
Sub-steps:
1. Remove the transmission from the vehicle (ensure to follow manufacturer guidelines for disassembly).
2. Inspect the clutch disc, pressure plate, and release bearing for wear or damage.
