illenium Posted September 24, 2015 Share Posted September 24, 2015 (edited) Hi Guys, I'm a lurker since April this year. I bought a 1994 Beta and since day one have struggled with the rear brake. When I first investigated after hours of unsuccessful bleeding I noticed its missing an oring the piston. To be more specific, its lacking the circular oring towards the top. I tried all my various rings but to no avail. Can't find a kit online either (within the US). Does anyone know the exact dims / thinkness of this oring? Its the one towards the top, not the one on the bottom of the cylinder. I would love me a working rear brake. Cheers Edited September 24, 2015 by illenium Quote Link to comment Share on other sites More sharing options...

betatechnopilot Posted September 24, 2015 Share Posted September 24, 2015 Goudrons is right. While not in the USA, Trials and tribulations has alot of Techno parts. Quote Link to comment Share on other sites More sharing options...
illenium Posted September 29, 2015 Author Share Posted September 29, 2015 Thanks guys, I have checked their website a couple times but I'm still baffled that I cant find an oring kit in the USA for what seems to be a popular bike here (for a trials bike) Biting the bullet...ordered. Hope this works Quote Link to comment Share on other sites More sharing options...
betatechnopilot Posted September 29, 2015 Share Posted September 29, 2015 I wish I would've thought about it sooner but a call to Bill Haskell at Balance Trials Supply in Colorado or Mike Damm at Trials Superstore are both good at finding Techno parts too. But Ian at Trials And Tribulations is a great guy and you'll have no problems with him. Quote Link to comment Share on other sites More sharing options...
