Gave the caliper another shot and no luck. I'm just gonna order another one to keep the project rolling.
This one ok? https://www.sip-scootershop.com/en/product/brake-calliper-piaggio_58573R00?cr=e993ab67-6807-4109-bbed-f6374ebf9f9b&gclid=EAIaIQobChMIl7Cg8MD49QIVOsqUCR1_vAchEAQYAyABEgI1aPD_BwE |

that one should be fine. just keep in mind the connection at the caliper regarding the the banjo and banjo bolt and sealing washers. they liked to flip flop around between sizes on those sometimes and that'd suck to get the whole thing and be mismatched or have to spring for connection hardware.

That's why I usually give the original parts a try. They will at least fit. Can always order some banjo bolts. Lots of winter left. |

have you tried boiling it in hot water?
what? you all don't have a hot plate and little post "for garage use only"? savages. anyway, I'm such a miser that if I ordered the rebuild parts I'd fiddle fuck around with it till I got it or I broke it in the process. you could also try 50/50 water and vinegar (to note, do not do that in the house on the kitchen range. you have been warned) |

I just get pissed when a part won't yield to my will, so even if a new one was on my doorstep yesterday, I would devour a PhD's worth of caliper piston removal information and beat on it until it submits. I live in a woman-less house with my two boys so I could bathe with a tub-full of engine parts if I chose. Sorry to paint that picture. if you have a new master that works, you can try hooking it back up and using fluid to force the pistons back out. knock it back on to the caliper mount with no pads, finger tight jimmy bleed it down and go to town while applying a little warm with a heat gun to the caliper body. for pure violence, just blow the seals out with torch. you're gonna replace them anyway. the smell and clean up is a bitch, but that's why you have cheap labor at your disposal! |
Wow looks great! making way more progress then i would have, glad they are in a good home. I guess my wife sent you with our old garden trailer tires haha!
Like greasy said, i would deffinitly try to hook up that old master cylinder, bleed it and use that to pop out the cylnders with a small plock of wood in between since only one tends to shoot out beofe the other. I have done this a ton on cars, and when one moves i work it in and out, then clamp it in and work on the other side. That caliper deffinitly moved last summer. As for the master cylinder, how about cleaning it really well and JB welding the window? it doesnt have any pressure and should clean up without issue. Anyway, let me know if you have any guestions on anything, my big contract for work is wrapping up soon so will have time to chat if need be! |

The scooters are cleaning up nicely and getting some tlc. Both solid bikes that will be well taken care of and enjoyed. Please thank your wife for all her help with getting my bus up the icy driveway and 2 scooters loaded into that little bus on that dark and rainy night. PS: I have a new sight glass and gasket for the mc. Old one pops right out. It's just a groove with an o-ring. |

But because it came to me this way, they don't bother me a bit. If a rock hits it, the kids bump it with their bikes, whatever...I will not be losing my shit like I would had I put a lot of effort into making pristine, That's just no fun and no way to ride. |
orwell84 wrote: Ok thanks. I put a wood shim in the caliper (to stop the pistons smacking together) and tried to push them out with compressed air but no dice. They didn't budge. I'd set it up with the master cylinder and hose and pump them out like you'd do when bleeding brakes… Just keep pumping and the piston will pop right out |
Popped the headset opening to clear out any blasting media. There wasn't any, but while it's open, it's going to give it a clean up and lube everything. I now have a cable oiler, so I will do that too.
Hoping to paint the tunnel this weekend when there will be a warmer weather window to apply and cure paint. It's been hard to find one when I have the time. Working on the master cylinder. That snap ring is difficult. My snap ring pliers are too clunky. The brake light switch needs to be replaced or cobbled back together. I will fiddle with it awhile longer for my own edification before prying open the wallet for a new one. I am considering replacing the wiring loom in the 200. The old one will need some splices and new terminals. The wire insulation is quite brittle in spots. The green wire especially seems to be made of cheese. It doesn't look like it would be that hard. Can anyone recommend a decent quality loom? Thanks. ![]() ![]() |

I remember doing my shift side switch years ago. It sucked. Especially stuffing the wires back in and having the shifter move without anything shorting. I know I can do a decent job with replacing some connectors, a few splices and some heat shrink. |
It's just one of those days...
Got my garage nice and toasty and ready to paint the tunnel only to find that the paint I was going to use turned funky even though it has never been opened. It might be useable, but whenever I have used iffy paint, it turns into a kick in the dick. It's the kind of place where a paint failure would be really hard to fix. I wrecked the seal putting the MC back together and one of the seals in the kit was wrong anyway, so done with dicking around with it. The caliper too. So on to an actual question. Will this caliper fit? It looks exactly the same as the one I have but SM does not mention the LML star under compatible models. https://www.scootermercato.com/Scooter-Parts/Disc-Brake-Parts/56220R Thanks. |

"If only I'd have been more patient..." Good call. You're doing great work. I'm also damn impressed with how you cleaned up that tunnel. I didn't do anything near that on the VBB or GL, but seeing you do it makes me feel like I should have. Oh, well... |
Thanks CM,
The tunnel was definitely overkill, just something I've become good at and it's the brainless kind of work that helps me unwind. Sometimes it's sandblasting stuff or taking a few thousandths off some hunk of aluminum in front of the tv. The usual cleanup, Ospho, rust paint deal really does make stuff damn near bulletproof, so I'm sure your good. Riding it often also does wonders. |
Today was more productive. I pulled a bunch of new wire through the tunnel to the horn cast junction box. It was pretty easy and better than splicing. I have a lot of euro style crimp connectors and wire left over from my bus project. The connectors are the same type. It's just a matter of duplicating whatever's there. Colors are correct too.
