Brake Fluid

EdGasket

So how much water do you think is going to enter a sealed, half-full container of brake fluid roneik? Not enough to make a gnat's p*ss of difference to your average car and I'll wager there'll be a lot less water in that sealed can than in the brake fluid reservoir of your precious mini just one week after your brake flush.

You do know that brake fluid goes a darker colour when it's absorbed moisture? It should be clear with a yellow tint, if so then it's fine.

The main point is if your putting fluid in either
You pads are getting low in which case they need replacing mechanics going to hate you for topping it up if this case.

Or you've got leak in either case it needs some attention the MOt was two months ago, a lot can happen in two months.

Water is non compressible - I thought that was the general idea of a hydraulic (brake) fluid?? As Richard has said the problem with water in the system and 'spirited driving' or even having sticky calliper's, worn disks etc is when the water in the system boils and you find the brake peddle hits the floor as steam is very compressible. Also in colder climates water freezes at a lot warmer temperature than brake fluid.


On 2 wheels with your reservoir being in plain sight its easy to have a visual indication of your brake fluid, light 'straw colour' from new fluid, tea colour (no milk) for older fluid.
