Exactly - they can't even get a brake light bulb type right!!!! MKV lights take a twin filiment combined tail and brake light - get a life!!!

I like semi - main reason being it's easy to switch either way - mineral to fully synth is seriously bad news

Ian, bit of change to the subject but what brake fluid would you recommend?
DOT 4 any make

- fer c's sake don't use fully synthetic brake fluid (scary stuff that is)

- marketing plus - it won't damage your paint work and doesn't absorb water so boiling point is a constant over the lifetime of the fluid

negative point - you may notice an increase in pedal travel WTF!

- Ian's points - Don't spill it (non synthetic brake fluid) and your paint works fine - change it every year and water absorption is minimal :wink:

True situation - OMG pedals hit the floor!!! I put it in the LC and I can tell you stopping two tonnes of car at 180 mph and having the pedal on the deck is not nice or clever - changed it straight back to normal DOT 4 and instantly got the brakes exactly how I want them.

PS I use an easi bleed so no there wasn't any air in the system :roll:
urrm ok how does that work you will notice a incrase in pedel travel??

unless you can compress the fluid ( seems illogical due to simple physics ( fluids dont compress) )

I was told it was very possible to get an increase in brake pedal travel in systems designed for "non" synth brake fluid and experience bore out that fact.

It is apparently incredibly difficult to change from mineral to synth - I used 4 litres of the stuff to fully flush the system thro - that wasn't cheap!!!

When you change the brake fluid it's fantastic - the brakes feel sharp and crisp - I change it every year on all my cars - when I changed mine to synth they initilly felt sharp and crisp but after a very short while the feel went away and I was left with softer brakes - this doesn't happen so quickly with mineral fluid in fact it happens so slowly you don't notice it untill you change the fluid again......

I think it must be due to the incompatability between the two types of fluid and I can't have got all the fluid out.... I am surprised by that after using 4 litres but on that basis would not recomend it to anyone with a car filled with mineral brake fluid

So in summary I would say if your car already has synth or mineral fluid then stick with whatever it has and don't try and change types
