I've just bought a onza zoot with the echo TR brakes on it, and after a couple of hours fettling it the garage and half hours worth of playing on the yard. I went out for a first real play and five minutes in the front brake lever fell off! Where it mounts to the master cylinder, it had just snapped. I've ordered a hs 33 now but just wondered if this was common with these brakes? no visible indications of it having a bang and the metal looks a bit "cereal box special" lol.
