The car has been in the garage since Friday, with regular checks on battery voltage.
All seems good, it has settled down to a healthy 12.61 volts, which is what a fully charged battery should.
The battery I removed, despite being fully charged by the charger and not on a car has dropped to 12.4 volts, so it is not as good.
Some more discussion on disk and pad bedding in here.
It does seem like I need to take a hard-work approach to the brakes, so I guess that is one for Sunday and the Supra meet I should be going to (I know the car isn’t a Supra…).
