Got a strange problem with my Echo brake. After finding out the thread in the TPA was a bit fecked, I took it all out, fiddled with it a bit, then got it working again. But now the brake is actualy SOLID just as the pads touch the rim. It's not even set up that brilliantlt, but there's no flex at all. Even when it felt fine yesterday (tiny bit of flex, how I like it) No matter how close the pads are to the rim, the lever is nearly at the bars. Even after i've bled it properly. It's like the piston is bottoming out, but it's properly bled and set up?
