Detach the fluid lines from the master cylinder using a wrench.
Remove the mounting bolts securing the master cylinder to the firewall.
Install the new master cylinder by reversing the removal steps and bleeding the system afterwards.

4. Check and Replace Slave Cylinder

Locate the slave cylinder on the transmission.
Remove the hydraulic line connected to the slave cylinder.
Unscrew the mounting bolts and remove the slave cylinder from the transmission.
Install the new slave cylinder, ensuring proper alignment, and reattach the hydraulic line.

5. Reassemble and Test

Reconnect the battery.
Test the clutch pedal for proper operation and ensure it returns to the resting position.
Check for any leaks at the master and slave cylinders.
