So ive had my ep3 for over a year now & ive had to replace my master cylinder 4 times now. The past 3 times were a different model & now autozone changed it up. But somehow i always end up with a leak somwhere with the cylinder. Please help me know why!

 

Either your installation skills are awful...or you're buying crappy CMC's.

I think you can use an EM2 cylinder on EP3's and they tend to last longer because they don't have a stupid "feedback plate" in them.

Buy a decent one at rockauto. It'll be cheaper than autozone. I've had an Exedy one in my TSX for a while without leaks or issues besides the occasional clicking from the "feedback plate" garbage.

 

I had help on past 3 replacements. This recent one i did myself & found possibilities for leaks. That plate you are talking about was the main cause of the leak. where can i get these cylinders instead of autozone? The current one i have has no plate, i guess autozone got other leaks as well & got them updated.

 

The EM2 is a 01-05 NON Si civic.

Rockauto.com is a website.

 

I would suggest upgrading to an EM2 cylinder (base civic cylinder, same as type-r if you believe it) or the OMNI power cylinder. I went with the OMNI since it has great reviews. I'd check EBAY or Amazon for either.
