Detailed instructions on how to replace clutch slave breaks are included in most product packages however it is best to perform it under the supervision of someone who has done it before, especially if you are doing it for the first time. Overall, the major steps involve as follows but need much detailed execution:

Step 2 –

Remove these cylinders by unbolting them using appropriate tools.

Step 3 –

Do not remove the band of the new clutch slave cylinder and install it by bolting and tightening. 

Step 4 –

Next, the clutch master cylinder has to be filled with the brake fluid. Now, loosen the slave cylinder bleeder and leave it open till the clutch fluid reservoir is full and the bleeder has a steady drip. Close the bleeder screw immediately.
