Hello! So I bought a Trenga Gen3 Rear Caliper setup from a fellow member (Jesse Colon) on here. I know these Gen3's have questionable braking abilities as well as a fairly unknown status on what parts were used/sourced. Let me give some background on why I decided to buy this: I used to play the crap out of ATV Offroad Fury 2, and my go-to quad was the Trenga Racing Blaster It was cheap Red is a pretty color I like keeping parts period correct on older machines If for some reason I cannot get this to work, I can always use the parts from this setup to make another hydraulic conversion So I knew when I bought this kit that I would have to do some digging around to figure out what does/does not work. This is what I've figured out: Enginetics made the master cylinder (I will find out what part number it is later) It uses Enginetics 303 brake pads The Slide Pins are essentially stepped collars that use 5/16"-20 or 5/16"-18 bolts They use springs to retract the slides (I've never seen that before. EVER) It appears that the MCP 1375P12 Rear Caliper is a direct replacement for this kit I have measured the springs and the slide insert: Here is a picture of the slide/bolt/spring assembly: So doing some research, I've found out that the springs seem to be major issue with this setup (I wonder why ). I tried to squeeze the spring with my fingers and I couldn't. There is NO spring to this...er...spring. I ended up finding bolts at my job and a lower spring-rate spring that I cut up into (4) smaller springs: For the collet/slide insert, well, I might have to make my buddy Sutty make it for me if I can't find one at a hardware store; thank goodness we got an in-house machine shop at my job.
