I was out driving tonight and i think that my clutch master or slave are going out. I push down the clutch and if i hold it in for a few seconds, the release point becomes very close to the floor. if i keep the clutch in, my car starts moving by its self

I have plenty of fluid.

Is there anyway that I can tell which one it is without removing them from the car? I doubt it, but it's worth a shot. Does one of them typically go bad first?

Anyway. so lets say I take out my slave cylinder since it is easier to get to, how can i check it and determine which cylinder is the bad one?

Also, if it is the master cylinder, is rebuilding it a reliable option? I can get a rebuild kit from Mazda Motorsports for pretty cheap.

it looks like the slave/release cylinder is a non serviceable part.

(i'm a poor college student for another 5 months, so the cheaper I can get by until then, the better.)

 

I think both are rebuildable , Garfinkle will not do just one for a customer any more , because they are the same age and to many times thay will go out with in a short period of time and a customer will think you did not do a good job. It is hard to explain things to people who do not know about cars. The slave is the easy one to get off and take apart .

 

10 bucks a piece for the rebuild kit for either... believe me im a broke college student tooo... sucks dont it!!

 

I got a reman slave and a master rebuild kit for my car. The rebuilding process is pretty simple. The only hard part was bleeding it once I got it back together. I gave up and left the bleeder a little open on the slave and it was much easier the next day. A pressure bleeder (http://www.motiveproducts.com/) would probably make quick work of the bleeding.

You should get a new hose, too. RX7.com, K2RD.com and others sell a braided SS line for the clutch for not too much money. I did all three on my car so that I wouldn't have to worry about it again for a long time.

Maxcooper is right ,do the three things at once and save time . The rx7 .com hose was $32 when it first came out years ago .

 

The slave cylinder usually fails first because dirt and debris in the hydraulics tend to collect at the lowest point in the system. But I agree with those that have recommended servicing the master, slave, and flex hose all at the same time. The total cost in time and materials is so low, why risk having to work on it a second time.
