I have a 2002 xtype jaguar 2.5l v6 AWD manual transmission my clutch pedal started sticking to the floor initially and I had to manually pull it up, after that I had to warm up the car before it would go into gear this usually happens every morning, since this morning I tried to put it into gear it is stuck in reverse and smoke started coming from the master cylinder, does it mean the cylinder is gone,I recently changed the clutch and release bearings

 

What are the Clutch Master Cylinder & Slave Cylinder all about?

A clutch master cylinder contains a reservoir that stores the brake fluid. It is connected to the clutch slave cylinder through hoses. When you push the clutch pedal, brake fluid flows from the clutch master cylinder to the slave cylinder, applying the pressure necessary to move (engage) the clutch.

It has internal and external seals that can fail. If the external seals wear out, the clutch master cylinder will leak brake fluid, reducing the amount of fluid in the car and causing the clutch to malfunction. You may also find leaked brake fluid down by the clutch pedal (inside the car). If the internal seals wear out, the clutch fluid will continue to circulate inside instead of being directed to the slave cylinder. In that case, the clutch pedal will go all the way to the floor when you apply the clutch.

Keep in mind:

• Whenever the clutch master cylinder is replaced, it is recommended to replace the slave cylinder as well. When the master cylinder goes bad, it is extremely common for the slave cylinder to follow suit.
• Note that some clutch slave cylinders are installed inside the transmission. To replace this type of slave cylinder the transmission has to be removed.

I don't know if it helps, but there is a TSB concerning clutch pedal sticking down. XT308-02.
