Another tool. Brake fluid tester to verify water content.
The brake fluid need to be replaced every 2nd year. ( More frequent than I thought before last change)
I noticed that both my bike's MC had the return holes clogged up when I changed fluid in February this year.
Last change was 4 years ago.
So easy to check if I must change every winter.
I got the tip from a colleague and biker friend.
A small simple tool with leds indicating OK or not.
I had to order a bigger one that can tell how bad. The price was low...
I ordered a brake fluid pump device for my car. Also from Amazon.
Connect to the fluid reservoir, pump to make pressure.
Bleed caliper when changing wheels, winter vs summer.
Empty the container with a syringe first and fill fresh fluid.
It has a 3l bottle for new fluid.
I'll try to use pump first and see how quick I must refill the car's brake fluid reservoir.
Mine for European car standard. Size of the cap.



EDIT:
Test the small tester.
The new brake fluid is OK, 0% water.

Test in water lit all leds.
