Just checking my records and realised it's been just over 2 yrs since I last did brake fluid,checked moisture content and 4% so just spent a pleasant hour in the sun with my trusty plastic tube flushing it through. Used the same 3/4 bottle of brake fluid I used last time 😎crystal clear and moisture content tested at 0% so gotta be better then what was in the bike 👍
 
Yes exactly that 👍been brilliant used it on Mrs car dads car etc, well worth the money. When I first got I tested it on brand new fluid and some old fluid just to see what reading, new was o %old about 4% so I knew it did the job.
 
I see that tester shows >4% so the true amount of water in your fluid could actually have been much higher.
Good job you changed it.
 
Nah ... must have been done by dealer at service, surely?

What dealer ? apart from first service ive always done it myself. Bike has less than 8k miles on it so didn't see the need to do it. However it will be done very shortly when bike is parked up for annual chucking down of salt festival.
 
I was surprised at the moisture level myself. Did 110000 miles on my vfr and changed brake fluid once, oops! must have been 20% water!!
 
Only ever experienced serious brake fade once.
An interesting experience.:eek:

I have once only as well, at the bottom of the hill at Fochabers many years ago. Try braking and having no brakes with a fully loaded artic. All i can say is thank feck there was no traffic coming from the Buckie direction otherwise they were toast. How i made a 90 degree junction was down to pure luck. When i did manage to stop i had to change my pants !!
 
Would have made an interesting re-arrangement of the auld kirk / antique shop across the roundabout!
 
These testers are less than £10 on eBay, may invest in one myself.
 
Ive only had one vehicle get proper brake fade. I was on a 1970s Kawasaki down a long his in the Peak District and the brake lever kept moving back towards the handlebar. I got to the bottom just after the lever hit the handle grip. Defy not a goo underwear moment.

If you never really work the brakes hard, the main issue is corrosion. Even a slight scratch through the caliper body anodising will corrode the aluminium. Ally oxide is more than 2x the volume of aluminium metal so the piston seals get squashed and chewed. BMW sell new seals for the back brake at under £20. The fronts come with new pistons at £60 a side.

It's much cheaper to change the brake fluid regularly.
