Crashed. I thought I escaped unscathed but turns out I broke the plastic lid and from a vintage bike there's no one selling the entire combi levers or just the lid itself. (in shops locally, I saw on ebay but with shipping, it aint worth the cost) It's on a 3x9 speed XC bike with XT parts ..

friends are egging me on for a 10 spd upgrade but I am not ready to shell out more cash on a 2 week old (2nd hand bike)

what do you guys think I should do?

fyi my combi levers look like this http://www.ebay.com/itm/VINTAGE-SHIMANO-DEORE-XT-9x3-BICYCLE-SHIFTERS-HYDRAULIC-BRAKE-LEVERS-M765-/151247697679

  • It sounds like its an aesthetic part - just put some duct tape over the area and get on with your life. – Batman May 8 '14 at 2:36
  • Most plastics can be effectively glued, if you find the right glue. And, of course, for a brake reservoir cover, you'd have to thoroughly wash the part before gluing. – Daniel R Hicks May 8 '14 at 12:16
  • The way I read it, it sounded like a plastic piece which went over the reservoir to make the setup look nice. – Batman May 8 '14 at 14:54

    The Shimano part numbers for the replacement are Y-6JK 98080 (for left hand lever) and Y-6JK 98090 (for right hand unit), which I found from the ST-M765 exploded view. If you search for these codes, you might be able to find a shop that stocks the part, or you could ask your LBS to order it from Shimano. However, since the parts are a bit old now, the spares may no longer be available direct, and only from retailers who have old stock remaining. – jbuk May 8 '14 at 14:57

    @Batman, yeah, so long as it's just the top piece in the diagram then it appears to be cosmetic, although with it removed the screws might bottom out in their holes in the reservoir body. However, you could just buy some shorter M3 machine screws if that turns out to be an issue. – jbuk May 8 '14 at 15:00

If you have only broken the upper part, which I have marked A on the exploded view diagram, then I don't think that serves a functional purpose other than making the brake levers look nicer. Therefore, you should be able to continue to use the levers so long as part B is in place, but without the added thickness of part A, the screws (part C) may be too long to fit in the threaded holes in the lever body. Shimano lists these as being 'M3 x 8', and they appear to be Phillips pan-head machine screws. You'd want to buy some M3 x 6mm machine screws to replace them and be sure of not bottoming out the screws.

ST-M765 exploded view excerpt

Alternatively, Shimano make available the entire reservoir cover assembly, (26) on the diagram, under the part numbers Y-6JK 98080 for the right-hand assembly and Y-6JK 98090 for the left hand assembly. You may be able to find an online stockist of these spares, or possibly ask your LBS to order them from Shimano. However, as M760 series Deore XT is relatively old, it is unlikely that any spares will be available direct, and you'll have to hope that shops have the parts already in stock.
