HOW TO REPLACE A CLUTCH SLAVE CYLINDER

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:

Park the vehicle on a flat base by raising the front of the vehicle. Put the transmission on gear and keep the parking brake on to prevent backward movement. Use a wrench to remove the hydraulic line from the clutch slave cylinder.

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.

Open the bleeder screw again and let the air out with the help of a helper who presses the clutch pedal and slowly releases only when told to. The bleeder screw has to be tightly bolted when the pedal is close to the floor and then the pedal is released slowly.
