Hi. Reassembling the old F2 that came to me in a million boxes. Am putting the brake calipers on and have discovered that I am missing a Pin A and the rubbers on all three Pin B's (45132-410-006) are not there. Does anybody know if the rubbers are available anywhere, or if not is there a fix for this. Also does anybody have a spare Pin A (45131-410-006) I could buy. Cheers

Hi there, the rubber parts are available from David Silver Spares http://www.davidsilverspares.co.uk/parts/by-part-number/partnumber_45133371006/ as is the Pin A but the prices look a bit eye watering, http://www.davidsilverspares.co.uk/parts/by-part-number/hpart_45131410006/.
Wemoto also have the boots, http://www.wemoto.com/bikes/honda/cb_750_f2_sohc/78/
Keep an eye on ebay as well
Cheers

Thanks for the reply Spitfire. Didn't make myself very clear on the rubber bits, sorry. Its not the gaiters that I need, its the rubber sleeve that goes directly onto the shaft of Pin-B and sits in the recess. Not sure these are available, the pin-B's certainly aren't. Not sure what to do about that, maybe try some rubber tubing or perhaps get some solid ones made. Anybody got any ideas, I guess somebody has encountered this before. Cheers

Which bit is the rubber sleeve?

Part number 45132410006 (17 on the diagram), they do have them in stock over at CMS, it would appear that the pin comes with the rubber boot attached,
Here's a link to the CMS part.

Thanks. Just checked out CMS, and £97.66p delivered for three little slider pins is a bit steep. I have the pins but for some reason the rubber parts are not on them. Think the PO must have taken them off as the pins have been chromed. Why they would chrome the slider pins that are hidden behind the boots is anybodies guess . Its left me with an expensive problem if its not possible to replace just the rubbers. Am tempted to try to replace them if I can find some details of rubber type and hardness etc. Was hoping there would be a tested fix that someone had come up with for this as playing with the braking system may not be my best idea this year. Will give it a bit longer, you never know what you can find out on Google. Thanks all. Cheers.

That's a bit steep, I would be tempted to keep a look out on eBay or try to run without the rubbers, don't know what function they do, keep out dirt, reduce vibrations ?

I am told they take up the thermal expansion and also act as a damper? Having thought about it for a while, I approached the problem from another angle and have managed to sort it. Just checked out which other Honda's used the same part, the CX500 was the best one. Went onto eBay and somebody was selling the used CX500 slider pins that I required at a very reasonable £20 for all three. After hours of searching for CB750 items without luck, jobs done. Easy once you figure it out, I guess most manufactures use identical parts in many models to save costs. A lesson I shall remember in the future. Thanks all.

Forgot to check which other bikes used the same part, there are a few

Royhall, I am building an 1979 F2 just now ( and for a while, Mick LOL) as a cafe racer so I have a pile of bits I ain't using, I.E. brakes wheels etc. Give me the wire ( or anyone else for that matter ) if you are short of anything. May be able to help.
