Subsequently, it is necessary to put more rags beneath the master cylinder and unscrew the pressure line with the help of a clamp by means of a small pick; then the line should be pulled with force and the open end of the line should be sealed. Lose the mounting nuts to separate the cylinder and the firewall, and in some cases you also have to pull the separate reservoir out of its place along with the master cylinder. For installation, first secure the position of the master cylinder on the firewall then fit the nuts and in the case where the reservoir is separated the slide it into the bracket. Tighten the mounting nuts, take the pressure line fitting connecting to the master cylinder, and apply the feed hose in case both models use the same brake fluid reservoir. Last but not the least connect the pushrod to the clutch pedal and replenish the reservoir with brake fluid that is of DOT 3 standard and then bleed the clutch system.
