Believe it or not the shimano fluid is up there with dot 5, the mugura is lower than all dot's as weve both thought, i change my fluid regular on all my bikes, iv felt the difference it's made on a race bike, it's a cheap and easy job to do mostly too.
Uh ??. So... DOT 5.1 "IS" hygroscopic, just like 3 and 4... Dot 5 is hydroscopic, silicone based so is the odd one out, And should not be mixed with the rest, i see youve done at least one change, So should know It's exactly the same job, you bleed fluid, you bleed air... Same job Unless ur...
Horses for courses on this point, DOT definately loses performance from absorbing water, i like most, bled my brakes after 3, 4 race meetings, and you would feel the difference in stopping power. DOT is better than a DOT & Water mix, Pretty sure it's part of the service my amarok is having...

If no faff wanted and you want something...
Another cracking campa, Same 3.0 motor, Pretty much the same layout as the kontiki just other way round, And bit more luxurious. Theres a nice one of these on e'bay now, priced reasonable at £45k, it's in newport just down from me.
If youd read all iv said you wouldent have needed to write this "not for even a second..." The first thing i said was to suggest my bosch battery chainsaw, iv not mentioned using a petrol one once. iv also said if not savvy with chainsaws then use a recip.
