Hydraulic brake lever woes

robbytres

Hi, I have recently installed a dura ace hydraulic groupset onto my bike and having noticed that there was some brake fluid leaking from the left hand lever, have tracked the source of the leak down to this bit, having previously thought it was coming out of the bleed screw above.
First thought was to tighten it up, but closer inspection shows it to need a specialist tool. A quick google of the problem revealed someone else with the same issue being told to go back to the dealer for a replacement lever.

Any ideas?

That's just a torx head isn't it? Could you not get a set of Torx bits and try those?

Otherwise you've hit the nail on the head, take it back to where you bought it from and get them to sort it....

It is a Torx but it's a 'no interference' one so you need the torx keys with the hole in the centre. Worth making sure the thread isn't crossed before tightening it. If it still leaks after tightening then it's a warranty issue.

I thought that, but the thing in the middle that looks like it might be a pin also looks like it might just be a trick of the light/reflection?

Certainly it doesn't appear dead centre to me which one of the no-interference pins would be.

Thanks for the input. I got hold of the non-tamper torx doobry, and tightened it up, and it's still leaking sadly, so have begun the process of returning it under warranty. Gutted as I imagine this is going to take a while to sort out so new bike will be out of action for a bit.
