Why does my abs kick on at a stop sign?
For whatever reason, when coming to a normal stop at a stop sign, the ABS occasionally kicks on. This is on dry pavement with good tires. It seems to only happen for the first stop after starting, so it may have something to do with temperature. I also never noticed the issue before the Winter. Any ideas of things I should check?

Just being below full doesn’t indicate a leak, since the level goes down as the brake linings wear. But it should be above the minimum as long as the you’ve got a decent bit of material left on them. Hard to judge fluid loss sometimes, because people like to ‘top off’ a sealed system.
