Customer Question

Hi Dr. Automotive. I had a bad slave cylinder on my chevy aveao 5 and replaced it. I bled the line to remove air and now have a clutch pedal that will not go down. if there was air in the line wouldn't it be a soft pedal?

Hi, My name is ***** ***** for the delay.

I will do my best to assist you

are you saying the clutch pedal itself wont go to the floor now?

Customer: replied 1 year ago.
t will not go to the floor. I can open the brass fitting on the slave cylinder, bleed it, and restart the process but it returns the same result--a stiff clutch pedal that does not go to the floor
Expert:  Tim's Auto Repair replied 1 year ago.

tell me,will it go to the floor with the bleeder loose?

Customer: replied 1 year ago.
with it open it will go to the floor
Expert:  Tim's Auto Repair replied 1 year ago.

ok,,does the clutch release?does it work?

Expert:  Tim's Auto Repair replied 1 year ago.

can you shift the gears with the engine running?

Customer: replied 1 year ago.
to understand correctly, you want me to leave the valve open and depress the clutch and release it?
Expert:  Tim's Auto Repair replied 1 year ago.

no

Expert:  Tim's Auto Repair replied 1 year ago.

can you shift the gears with the engine running?

Customer: replied 1 year ago.
to understand you correctly, you wanted me to open the bleeder, depress the clutch to the floor, and close it to prevent air intake. start the car and try shifting the gears?
Expert:  Tim's Auto Repair replied 1 year ago.

no,i want to know if you can shift the transmission now,with the engine running and the clutch pressed as far as it gos

Customer: replied 1 year ago.
No
Expert:  Tim's Auto Repair replied 1 year ago.

ok,,so,,the clutch isnt releasing at all,,correct?

Customer: replied 1 year ago.
Correct, it is on the floor and will not come up unless pulled up. Once up, it will not go down
Expert:  Tim's Auto Repair replied 1 year ago.

the pedal wont move at all?..this is strange

Expert:  Tim's Auto Repair replied 1 year ago.

you push and it is just hard?

Customer: replied 1 year ago.
the pedal is hard and will not move
Expert:  Tim's Auto Repair replied 1 year ago.

it sounds as if that new slave has some debries or somthing in it stopping the fluid from filling it to push the actuator

Expert:  Tim's Auto Repair replied 1 year ago.

it does blow fluid out of the bleeder//right?,,

it did work before you replaced the slave,right?

Customer: replied 1 year ago.
It blows fluid out of the bleeder, the piston moves by hand, when uninstalled. Don't know if it worked prior to install, New from store. The old one craked letting out brake fluid causing replacement
Expert:  Tim's Auto Repair replied 1 year ago.

please explain..

you have never seen it work?

Customer: replied 1 year ago.
It's a new slave cylinder from store, just installed. I can't say that it worked...the old one did right before it cracked causing me to replace
Expert:  Tim's Auto Repair replied 1 year ago.

ok

Expert:  Tim's Auto Repair replied 1 year ago.

if the old one worked,,there is no reason why this one shouldnt work if it is good

Expert:  Tim's Auto Repair replied 1 year ago.

to me,from the way you explain,it sounds as if that new slave has a blockage

Expert:  Tim's Auto Repair replied 1 year ago.

Clutch Pedal Hard to Push (Hydraulic

Expert:  Tim's Auto Repair replied 1 year ago.

from the way you explain,,it sounds as if you may need to try another slave..if it isnt the slave,it must be the internal of the clutch release bearing or fork,i wouldnt think this sense it did work with the old one

Customer: replied 1 year ago.
Should I remove it and drain it

Thank you for your help. Must call it quits for tonight. Will post again tomorrow on thread.
Expert:  Tim's Auto Repair replied 1 year ago.

ok..let me know how it gos

thanks

Customer: replied 1 year ago.
one last question before i reattack this tomorrow after work, the piston of the slave valve, is it supposed to be under constant pressure from the lever that it is seated into? The lever seems to be wide open. i can send a pic tomorrow after noon
Expert:  Tim's Auto Repair replied 1 year ago.

there should be no pressure on the slave unless the pedal is pressed..

it works just like your brake calipers

Customer: replied 1 year ago.
okay, thanks, ***** ***** pressure there. the piston from the slave cylinder is seated in the lever/fork but not under pressure. Just at a loss right now until i take it apart tomorrow.
Expert:  Tim's Auto Repair replied 1 year ago.

sounds like the slave is clogged/damaged
