what brake fluid can i use???i have a 06 636 and it hass the hhd big rotor kit 4 piston hand brake with 13mm magura and after i ride for 20 min it over heats and loses pressure so what are my options ???

 

bel ray dot 5

 

motul rbf 600 is bad *** but make sure you flush the whole system with it cause they recommend you dont let it mix with other fluids ..

also check to make sure your brakes arent dragging when they get hot , over filling the reservoir can cause this because the brake fluid expands when it gets hot so only fill it to the full line ..

if thats not your problem then make sure your foot isnt resting on the brake , and if thats not it stop raping the brake ..lol

 

i HAD THE SAME PROBLEM i SWITCH TO MOTUL 600 ITS A SYNTHETIC DOT 4 THAT WORKS REALLY GOOD i HAVN'T HAD ANY FADE ISSUES SINCE i STARTED USING IT.. THERE IS ALSO A SYNTH CALLED 5.1 THAST WORKS GOOD TOO

 

you have to be carefull using some 5.1 brake fluid because some of those have silicone in them and you dont want to use silicone in a brake system not designed for it

 

Yes dot 5 is a silicone base and you can't mix with 3&4 , but the motul 5.1 is a synthectic fluid it doesn't have silicone in it niether does the motul 600

 

I uesd to run the blu ray but quickly found out that it was not that great, and it breaks down fairly quickly. My boy Fuzzy had me switch to the RBF and i have not yet had a problem, and its been in their for almost 2 years now.
just my opinion tho

 

thanks for the input

 

I use the Liqui Moly 5.1. High boiling point and does not break down quickly! Never cooked a standard RR's rear brake and I was hard on the foot.
