Had pedal stick issues on my DE, so rather then buy the same shitty oem one I decided to get this. just wanted to get some opinions from people that have done it on here. I did some searching through the forums and noticed some people had issues with theirs gunking up the fluid when they switched it. ended up having to send it back and get a new one. I also saw people saying they had to switch stuff out with oem and such. As ive never done this before, is there anything I should know or look out for? and is there anything else needed besides what comes in the kit from concept z?
