Thanks, the rear brake light is fine and only comes on when the lever is pressed.Just a reminder, check your rear brake light adjuster switch, especially when adjusting the lever. You don't want it illuminated all the time or not coming on when it should. There's a plastic nut tucked in on the switch (kind of a PIA to get to) to adjust the switch..
If the bedding in doesn't get any better, I have/used a Mity Vac (don't know if its available down below) when I replaced my rear line with SS braided.
If not, you might have some some air where the brake line rises from the caliper . A fix for getting it out, pull off the caliper, block the piston so it can't COME OUT, hold the caliper higher than the master cylinder, so the air rises to the caliper and can be sucked out or pump/bleed (normal, no fancy tools bleeding). That's the only place air can be left, between the caliper and the rear brake pump..
I went for a bit of a burn 120km and the rear brake is now perfect.
Cheers
