Hi folks. Thank you, for any help here! So, I've been going through the brake system on the front of the 2008 Jonway yy150t-2 and one of the caliper guide pin bolts for the brake pads was so frozen in there that after 2 days of trying everything from liquid wrench type lubes, heat, cold, banging it with a hammer, different hex wrenches... it stripped inside the head. I drilled out the head and down the center to get an extractor in there and yes, it broke in there. I got some vice grips onto it between the two brake pads, it's a no budge situation. I've found a couple of used calipers listed on Ebay yet, answers to determine if their caliper will fit on MY bracket, are very slow and mostly, lazy .Even for new ones, I'm having a really hard time finding input on what ones will work for my scooter and bracket. I have measured center to center the caliper to bracket mounting holes (64-65mm). I'm reaching the limit of what this scooter is even worth considering, I still need a seat and a tire for sure (Another $100 - $120) so, I can't just throw money at and "make a wish" that what I order is correct. And at this point, I really need to find the best pricing, new OR used. Even the new ones that I see, may be oriented the same as mine but list no specs, even though the same listing always warns you to check your specs before ordering, insinuating that they are unwilling to accept returns . How in the world are MY specs any use if the sellers don't list theirs and take forever to answer a request for info ? Even when they do reply, they don't know much of anything helpful. And in the listings, either the bracket isn't pictured because it doesn't come with one, is different, or doesn't clearly show the bracket to compare mine against. Is anyone here familiar with the compatibility of the calipers? I found a couple, used. One is said to come from a "2008 SUNL 150CC Scooter, with 12" wheels " www.ebay.com/itm/171939823520?item=171939823520&viewitem=&sspagename=ADME:X:RTQ:MOTORS:1123&vxp=mtrThen theres this one... from a Jonway that I'm not sure if it's the same as mine. I dont see "MC-13" referred to on any of the identifying plates on my scoot. www.ebay.com/itm/310715011732?item=310715011732&viewitem=&vxp=mtr If I could even be SURE of which new one would be correct, I may go that route too . I KNOW there are some very helpful vendors out there but, I'm not running into them on THIS lap around the track. Here's MY caliper...

Thanks Alleyoop ! Can you glean any insight on that first link item? I'm paranoid that I'll spend money on the new one only to end up in the same boat when I try to transfer that cylinder from the top of the caliper. I'm hoping to line up some options . What is that, by the way? ABS?

The bracket came off a lot easier than I thought it would but, yes, that cylinder is giving me a very hard go of it. It's sitting in penetrating oil now, before I give myself an aneurysm. No work bench, vice, spiffy tools. Just hand tools and a patio.

I've been scouring over that listing and I'm confused ,evidently. The 65mm measurement seems to be good but, assuming that when measuring bolt to bolt, one would measure from the center of one bolt, to the center of the other bolt, here are the measurements that I get... The 65 should work here as the bottom measurements mount to the scooter and I would be re-using this bracket... But where is the "44mm" measurement coming from that I keep seeing on listings,including this one? Is it pertaining to these stay bolts? Center to center is 44mm for me, on mine. I'm just trying to get my brain around the specs I'm seeing out there because, there doesn't seem to be any uniformity to anything that I'm seeing, and trying to make darned sure before I make this nightmare any worse. Center to center...

If and when you get this caliper source sorted out,,, do yourself a favor and get a tube of copper based antisieze,,,a little dab goes a long way and really helps keeping bolts / screws from freezing

The caliper Alley linked is the correct one,,, and I wouldn't worry about the silly "abs" cylinder ,,,, leave it off,,, a bigger piece of kaka was never invented ,,, if the new caliper has the hole to mount the abs pile ,,, plug it and call it a deal

Sure that first link for 16.99 will work just use your bracket to mount it. Alleyoop

also as far as penetrating oil goes, better than most you can buy is a mix of acetone and trany fluid. and wd-40 is not a penetrating oil.

If and when you get this caliper source sorted out,,, do yourself a favor and get a tube of copper based antisieze,,,a little dab goes a long way and really helps keeping bolts / screws from freezing Oh, I'm glad you reminded me! I have a tube in the locker that I meant to lay out so that I would remember to use it Squash washer, check! The (NOT) ABS... When I was browsing here on brakes last night, I looked into that cylinder and I'm pretty sure it was jct842 that I read, saying it was crap too. I read an article that he posted and it pretty much confirmed it, too. I will gladly leave it off, once I can GET it off, lol! cyborg After that story, I will do my darnedest to omit that thing, even without Coronas to celebrate, lol! Thank GOODNESS, the brake line will connect directly to the caliper without me having to track down a fitting or anything . Every step of the way on this seems to be loooong and contingent on something else. (Thus,the bike is still stripped to the frame mostly. Putting the panels on is what I'll save some Smirnoff's apple Twisteds for. HEY, I'm a girl! I like those flavored things! Lol!) Alleyoop , that Corgi illustration got the point across perfectly, and I truly did laugh aloud, thanks! Tranny oil and acetone , yay! I'll make some! I only use WD-40 for minor things and have liquid wrench for penetration Thank you all , for chiming in

i wasn't kidding about the abs cylinder delete,,,it's nothing more than a floating piston with an o-ring around the outside edge with a spring behind it,,,the theory was to take the sharp pressure spike out of the line in a panic stop so the tire didnt start sliding ,,,they always leak with time and brake fluid gets behind it rendering it useless or worse introducing air into the system making it mushy and in my opinion dangerous,,,i always go by the off road adage "if it ain't there it aint fu(kin up",,,or to the pc crowd,,,less parts less problems,,,i use the first cliche myself,,,,nothin like being stranded in the middle of the mojave with a broken bike over an overly complicated part that went bad,,,,,ask me how i know,,,6 hour walk out ,,,nice,,,then i had to go back get said pile o kaka and come back out again,,,those Coronas tasted real good after the first schlep out let me tell ya,,,in mid august too
