clutch pedal sank!

Hey. I noticed that my clutch pedal releases right off the floor now. It used to release a lot higher. I am wondering what this could be?

i added some fluid cuz it was low. the pedal releases way up high now. i also noticed a fluid stain coming from the bottom of the master cylinder like it was/is leaking a little bit of fluid. its coming from there the master bolts (with the 2 bolts) to the firewall. would this be a bad master cylinder? how hard is it to replace?

Why thank you!

I'd keep an eye on that leak. If you have to keep adding fluid and you notice it keeps coming from there I'd say that's your problem. Master isn't too hard to change, just have to drain the fluid, swap the unit, refill and bleed the system. First things first, keep an eye on it.

Although the slave went with your trans then correct? I don't have any of your driveline I think.

so would you recommend installing JUST a new master or BOTH the master and slave?

just do both. they are not expensive. btw, if you leaked fluid on the car id suggest washing that off. that fluid leaked on the chassis is a recipe for rust.

they are both fairly cheap. its kinda cheap insurance just to do both. i would suggest getting a stainless line to remove the stupid damper right before the slave too.

dockside55 - i will surely do that. thanks for the tip.

93sapphirecoupe - where can i get the stainless line with the fittings and is it hard to remove the damper? how much more stiff will the clutch be without it?

i dont think you will be able to notice any more stiffness but that damper can cause issues. its only there to reduce driveline shock. my clutch would slip sometimes before because of that stupid thing. plus it makes bleeding the clutch easier

can anyone tell me the length it needs to be, so i could measure the line at advance auto parts to see if it will work? i would appreciate it. i cant find any thread that actually tells you the length or size fittings.

i took a look and it turns out it already has the damper box delete. the hard line is pretty bent up, but still works. ill prolly end up switching out all the lines for braided ss lines in the future. also, the clutch went back to how it was originally, but will still be doing the mast and slave install.

I just got done installing the new clutch master cylinder and the new slave cylinder. the clutch is back to normal but releases very high. im gonna look into adjusting it.

would someone be able to tell me how to adjust the clutch so it releases about half of its full travel?

There is an adjustment thing on the top of the pedal. Should be really obvious when you look at it.

im guessing its just the lock nut on the plunger arm of the master that i need to loosen? then twist the plunger arm to adjust the pedal throw?
