Lost Pressure When From Clutch!!!
 
Just now after i got off work, i drove and notice that my clutch lost alot of pressure. I stopped at a gas station and checked for leaks and didn't see any. But my clutch reservoir was empty. Where else would i look for leaks? i looked by the slave cylinder(Bleeder valve) only because it was dark. please help me out thanks

Fill up the reservoir, pump the clutch repeatedly, and drive around. See if the level ever goes down. My car does this about once a year or every other year (when the weather first gets pretty damn cold). After filling the reservoir, it doesn't happen again. Obviously there's a leak, but apparently not a major one for me.

Sounds like you guys have the problem I had. Your not seeing any leaks because its the seal on the pushrod on the opposite side of the firewall. You also lose pressure in the cold because well most people know that cold whether can make rubber seals shrink and they expand when warm/hot. Get upside down on the floor of the car and look up where the clutch master pushrod comes through the firewall to see if there's fluid. If not it could be the slave. Might as well replace it before it totally shits the bed like mine did and you can't even get it to go into gear.

what he said....

you may have to bleed the clutch too right? i mean couldn't air get into the system now that its completely dry in the reservoir?

Yes, Check the seal on the pushrod underneath on the pedal side. IF ITS LEAKING REPLACE IMMEDIATELY. IF that's not the culprit, sometimes the hose, that goes from the resevoir to the master cylinder, can have a small leak.

It's best to tighten the clamps & fill her up, see if that works.

if you topping the fluid more than few times in short period of time. Your clutch master most likely going out. I swapped out my master and slave @ same time.

First, examine the clutch master cylinder, which is typically located on the firewall near the brake master cylinder. Take a close look around this area for any signs of fluid leakage or damage.

Next, inspect the clutch line that connects the master cylinder to the slave cylinder. Look for any visible indications of fluid leakage, such as wet spots or dripping fluid.

Don't forget to thoroughly check the clutch slave cylinder itself. Although you mentioned looking near the bleeder valve, make sure to inspect the entire cylinder for any signs of leakage, such as wetness or fluid accumulation.

Additionally, pay attention to the clutch hose, which is a flexible component that connects the master and slave cylinders. Examine the hose carefully to see if there are any signs of damage or leakage.

Lastly, it's important to observe the behavior of your clutch pedal. If it feels spongy, inconsistent, or sinks to the floor, it could indicate a problem within the hydraulic system.
