Casa eccentric rear brake pins

Postby Knowledge » Tue Jan 06, 2026 11:52 am

I have a set of the above for assessment for a forthcoming Oily Rag article for Jetset.

These are selling very fast (SLUK have already sold out) so my article might arrive a little late for some LCGB members.

I will offer this advice ahead of publication. FOLLOW THE INSTRUCTION SHEET and you will be fine. The results are very promising so far, though the current snow on the ground is preventing me from testing the brake.

DO NOT follow Steelweasel's video in YouTube. He starts his video by stating we should read and follow the instructions and goes off and does his own thing. It takes him forever. He removes and refits the shoes time and time again when there is no need to do this. The video is 44 minutes long!

By comparison, I set-up the eccentric pins in the correct orientation in about 5 minutes and took another 5 minutes to secure them in that position using the shims provided. Simples.

Sticky has prepared a video to support this product which is less than 7 minutes long. TURN ON THE SUBTITLES via the settings icon. [youtube-share]https://youtu.be/Fdvd0prrR4U?si=kFABHOVfrqwC7XnY[/youtube-share]

I hope this, and my future article, help you guys with this very neat product.

I look forward to trying these myself. They look like a great way to address the historic problem of poor rear brake on SIL casings.

Thanks for the heads-up Knowledge, I look forward to the performance update when road conditions allow.

I don’t have a SIL casing to test and I am not certain that this kit can fully address the issues that are inherent with the badly drilled brake pivot. However, if it can improve the contact for the other shoe and most of the “bad-pivot” shoes, things have got to be better.

Having fitted my hub-with-a-window to check the tolerances, the new shoes I have fitted and adjusted look to be spot-on. I might find out tomorrow.

additionally to this kit, mr knowledge, you could rectify any bad casings, where a hole is ovulated in the cam area, with a bush after drilling out to suit 8-)

I ordered some without checking and presumed incorrectly that they'd come with the alignment tool.

Not back in stock for a while yet. So watch out as they're pretty useless unless you have the right tool.

Oh well.

Hi all, bought one of these brake pin kits fairly recently which I must say arrived super quick in the post! So, armed with the instruction booklet that came with the kit & a brand new set of Makino brake shoes I set about fitting the pins this morning, all seemed fairly straight forward & I got both shoes set with them just touching the tool arm bolt, the bottom shoe touching slightly more so, but that was the best I could get it, unfortunately when it came to refitting the rear hub I found it was binding on the shoes after I tightened it down( I had slackened off the brake cable adjuster first before refitting the hub) so, removed the hub & started from the beginning again!! Tried again with the same result! ended up putting my old shoes back on & with the hub refitted all was fine ,so either my brake pin threads are really misaligned (SIL 200 casing) or my hub,which is a Uni one & only about 3 years old is slightly oval. Might have another go with it using a different set of shoes sometime in the future.....

Rich, if you are stuck you can borrow mine.

I bought a set but won't get round to fitting for a while...

All the feedback is beneficial!

Interesting. When you fitted with new shoes were you able to get a pin setting where the tool wasn't touching the shoes at all (no tension on arm)? If not then it is possible that the pin holes are really out (Broady says he's seen 2mm on Indian casings, and also mis-drilling of the hole for the cam. If you can't get the tool to rotate freely then you won't be able to fit a hub. But you also wouldn't be able to fit a hub over new shoes with the standard pins. If you assemble with both arrows of the pins facing each other then there is definitely more clearance for any hub than with standard pins.

Is it a case that the hub was binding all of the time or only for part of a rotation? If it's on-off then the hub is warped.

When we checked an Indian casing we could not make it perfect (the shoe to tool gap was 1.6mm on std pins) but we could improve things enough to get a hub over new shoes; which was not possible without skimming before. We are considering making an XL-offset version for Indian casings to solve that problem but we need more feedback to know if it is definitely required.
