Triumph aftermarket brake lever issue?

[Warsteiner]

If you want to understand where is the fault, you've to take apart both levers and compare them.

I bet you'll have just to add a washer or use a bigger bolt.

You could remove the nut and install a metal spacer in it's place, buy a longer bolt and a new lock nut on the bottom.....but I don't think this would solve your problem as no matter how much you tighten the bolt....it is not going to crimp that thick aluminum. I think you need to remove the nut/bolt and use a thin washer inserted between the lever and purch to remove the up-and-down play then reinstall the current nut/bolt.

Jam a screw driver into one side of the nut (small pocket screw driver or any piece of metal that can wedge in there) and then use an allen to tightening it.

If you do what AZEKightz said to do it will work. A friend just bought a set of levers from china off Ebay and they had the same problem. He asked me to look at them and I was able to tighten them up by locking the nut in place with a pick tool and then tighten the allen bolt and they are nice and snug now.

Tried the above as a first step but no luck - the gap between the metal mount and lever is too large still. Pretty sure it is a machining issue between the brake mount and lever thickness - about 1mm difference. I'm thinking a half mm spring steel open/split washer or something similar with a bit of lube to fit in the gap, but haven't found the right one one yet.
