Was out driving my 81 rx7 when the clutch started to go out. Got it back home and started doing a few checks, clutch fluid is full. Carpet is not wet on inside at all. I can stab the clutch and it feels semi normal(a bit looser then normal but still activating) but if i gently push on it it just sinks to the floor without engaging. Whats the deal here? im used to when a clutch goes out its the slave or master and it soaks the floor mat and your pant leg. or am i missing something here?

 

The slave or master can go without dumping fluid everywhere. The last time I had a slave cylinder go, it didn't make any mess at all, it just wouldn't hold pressure due to badly deteriorated rubber seals.

Whatever you do, replace (or rebuild) both at the same time.

 

Replacing Master & Slave pistons at the same time is a 'pro-tip' - as once you replace one, it holds more pressure than the other and blows the other one out.

Open the hood and grab the boot coming off of the slave cylinder with the steel rod actuator going to the clutch fork. Pull the boot back from the fork indentation and I'll bet you get a handful of hydraulic fluid! They leak under the boot and fill the boot but don't leak on the outside so harder to locate.

Rebuild kits are the best and cheapest bet - and while you're at it may consider swapping the clutch hydraulic line with a $28 stainless braid and you'll never have to worry about the line again for the rest of your life. Good luck,

 

replaced both the master and the slave cylinder, problem solved, dont know which was bad but my guess would be the master. anyways all is well once again, thanks for the help fellas
