Happy Winter Everyone. Long time no post! I’m in the middle of restoring a YPVS (48H over here in the US). Transforming it from and red and white to a yellow and black, keeping it as stock as possible. I’ve got to rebuilding the brakes and I’ve found I’m missing an o-ring on one of the caliper pins. Does anyone know where to get replacements? I did my due diligence and searched this forum but no leads. Seems like you can put something else on there. They are however a little unique. They are quite wide 4.5mm and have a groove around the outside and another slot perpendicular to it to allow air to get out. Tried Norbo’s shop and Yambits, but not listed. www.relentlessquestmotorcyclerestorations.com/work/project-one-s32mj    |

I think I came up with a sensible alternative to the OEM component. I purchased a box of #83 o-rings from the plumbing section in Home Depot. 1/2" OD, 5/16 ID x 3/32 CS (cross section). They contain Butadiene which is an oil resistant rubber, nevertheless I only used a little red rubber grease. I put 2 o-rings on which satisfied the middle groove around the circumference. For the perpendicular slot that is there to let out air, I heated up a small square edged file and with the o-rings installed, I lay it lightly at right angles and melted a shallow slot. Works a treat. With a bit of the rr grease in there it slides back and forth smoothly and you can hear the air hiss out. This'll work if I strike out getting something better.   |

Hi there, I'm in a similar spot. I need replacement pins as well as the seal. I've tried to look on various OEM supplier websites to see if any parts are still available (Fowlers, CMS, etc), but none of them seem to display the correct calipers. I've even checked for XJ550 as it seems that they have been used on them as well, but can't find them listed.
I will be buying the pad pins, pad retainers, pistons and seals from Norbo, but wondered if anyone knows where I could get the other bits?

I have a full set of the pins, just one seal missing from one of the smaller pins, get in touch if you're still after these. |
