I have a 1991 Mazda Navajo that the clutch pedal goes all the way to the floor and won't engage. I have noticed that the fluid in the plastic reservoir keeps going low. After I fill it up the pedal will get better. I can't seem to find any leaks as to where the fluid goes. :?:
I replaced the clutch 2 years ago. Can you tell me what this could be? Would be greatly appreciated.
THANKS

Sounds like you have a SLAVE cyl problem....in order to replace it you need to remove the tranny again....

You can confirn this by removing the rubber boot on the left side of the tranny and looking for fluid around the slave/release cyl

It could be that, but I always like to start with the cheapest solution first. Check to see if the bleeder valve is cracked open. If so, you would be constantly losing fluid. Just a thought.

Thats a good idea, but I dought that it would come loose after 2years. AS I previously stated I would check the bellhousing yourself by removing the plastice boot and look for fluid around the slave cyl.

Suggested Repair

Check that the clutch bleeder valve is fully closed. Remove the rubber or plastic boot on the left side of the transmission bellhousing and look for fluid around the slave/release cylinder. If fluid is present, the slave cylinder is leaking internally and the transmission must be removed to replace it.

Conversation Summary

The owner of a 1991 Mazda Navajo reports the clutch pedal going to the floor and not engaging, with the reservoir fluid repeatedly going low and no visible external leak. Filling the reservoir temporarily improves pedal feel. The clutch was replaced two years earlier. Experts suggest first confirming the bleeder valve is closed, then inspecting the slave/release cylinder by removing the bellhousing boot and looking for fluid. A leaking slave cylinder would require transmission removal to replace.
