Just a word of caution Simon the Silicon Dot 5.0 is not miscible with any other brake fluid - if possible use only after a full dismantling with clean master cylinder, caliper innards, flexi hose & pipes.
If you have just drained the master cylinder & pumped out the fluid using some Dot 5.0 as a flushing agent then after standing for a day I would pump out some fluid from the caliper bleed nipple into a glass test tube or similar to check for traces of the old fluid.
The new silicone fluid will float on top - the old fluid will be in a puddle at the bottom like a sediment.
PS Don't ask how I know this.
A short ride might help the shake down.
