I want to replace the 2 small o-rings to connect the 2 caliper halves once you separate the chambers of the SRAM Guide R brakes. Does anyone know the o-ring size for these please?

Read that whole manual. Had no clue there were that many parts of a brake.

Don't bother googling, it's impossible to find cause SRAM doesn't list the sizes anywhere. Probably cause they want you to buy the whole kit. Not sure if they're the same, but it's size 4.5x1 on the RSCs.

Yes I did the google search prior without a result - hence why I asked on the forum. Yes the RSC will be the same size.. Is the 4.5 the outside diameter of the oring?

Yes, it's measured in outside diameter (cause thickness varies so inside isn't always the same). I have about 50 of em that are part of a set I'll never use. Would be happy to mail em to you if you drop a message.

Edit: How did you even diagnosis that and know you needed new o-rings? That's pretty impressive you were able to figure that out considering all the small parts.

Thanks very much for confirming and the offer to send me some of yours. I'm in Australia so I can easily source them locally and quickly. Really appreciate it though! Till next time...
