Clutch Hydraulic Actuator

I have a '96 Pathy with a manual transmission. Today the clutch went to the floor as I was trying to shift gears... and did not return. Luckily the Pathy was in a useful gear and I was close to home... the clutch was still engaged so I made it home without stopping.

 

It's now up on jackstands, and I can see a hose hanging down... that must be the hydraulic line to the clutch actuator cylinder. The end attaching to the actuator is hanging free, so it's no wonder the pedal went to the floor.

 

First task will be to reattach the hose and bleed the system... I should have that done tonight or by latest tomorrow.

 

But I'm wondering if anyone has ever had a problem with the actuator cylinder... could it be bad? If it's stuck, and you pushed the pedal, it's possible to overpressure the line causing it to come loose... anyone ever heard of a stuck actuator?

 

Is there something else that could be wrong? Let me know your experiences. Thanks in advance!!!

 

I'll let you know what I find out tonight as I'm laying on the cold garage floor!

I'll have to replace the rubber hydraulic hose going from the actuator to hard line... the metal fitting at the ends of the hose were totally corroded which is where it failed.

 

I'll pick up a replacement tomorrow.

 

Anyone know the bleeding procedure for the clutch? Thanks!

1. Fill the master cylinder with fluid and leave the cap off.

2. Attach a tube to the bleeder valve and stick it into a jar/can or something.

3. Pump the clutch pedal.

4. With the pedal all the way down, open the bleeder valve, release the fluid, close the valve, release the pedal.

 

If the lines are empty at the beginning, you might want to just take off the valve and use your finger instead, but once fluid starts coming out you should put the valve back on and use it.

 

Repeat step 4 until the fluid that comes out is clean and doesn't have any bubbles.

 

5. Tighten the plug (with the pedal down), fill the cylinder again and you're done.

 

(Thanks Chilton! :P)
