Can you tell some how if brake fluid needs changing or is it just a age time to change,
the car has .4 fitted as far as i know the oil is 2 years old

Look at the brake fluid colour, Depending on what sort of life it has had and can vary dramatically.
the car has only done 11,000 miles from new 2 years old
Any track life? On our race cars we will change fluid every few meetings but thats because we tend to overheat the fluid.

The only reason to change brake fluid is because it absorbs water - and that reduces the boiling point of the brake fluid.
...and we all know that's bad because IF the fluid boils you'll lose all braking.
It's very difficult to tell how much water your brake fluid has absorbed without testing with special equipment therefore vehicle-manufacturers
always recommend a service interval for the brake fluid based upon it's likely rate of absorption of water.
All of this means that you SHOULD change your brake fluid around 2 years in service or whatever your manufacturer recommends
Change it and pur blue racing fluid in as it turns green when it's absorbed to much water or been over boiled to many times
weigh up the cost of changing your fluid every two years, compared to running into the back of another car because your brakes boiled - simples!

Its a road car NOT a race car
Thank you for your help

Racing brake fluids should be avoided unless the brake fluid is operating close to fluid boiling point.
Racing brake fluids absorb water much more readily than DoT4 or DoT5 fluid, and any absorbed water will drastically lower the boiling point of the fluid and also cause internal corrosion of the system.
Most ester based racing fluids also are more inflammable than normal ester based fluid.
With DoT 4 fluids changing the fluid every 2 years is more than really required, DoT 5 fluids are generallyna bit more water absorbent so if you push the brake temperatures up then. change it every year.
