Have had someone ask me to service his brakes but, they are insisting that I use DOT 5. My supplier only lists 5.1, is there any difference ?
-
Found this Trigg
Image result for difference between dot 5 and 5.1
Since DOT 4 and 5.1 are both glycol-based brake fluids they are compatible with each other, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.

Interesting, but why not just use DOT 4 ? Any benefits to using 5.1 or draining the whole system and using DOT 5 ?

The only benefit I can see with DOT 5 silicon based is its kinder to the paint and supposedly doesn't need to be changed as often.
I think it also has a higher boiling point not that that's ever an issue for road use.
-
DOT 5 is hydrophobic. So doesn't require changing as often and doesn't damage paintwork. Allegedly. :)
-
That's what I said :P
I don't trust the paintwork claim. Someone needs to try it out. ;D
-
Yes dot 5 is silicon and gives a good shine to your paint when you wipe it off much better for our classics paintwork

If you use silicone fluid in a system previously filled with a non silicone fluid you need to change all the seals apparently otherwise they will swell.

Buy a litre and send it to me, I have some tanks to try it on ;D ;D ;D

I will buy you a litre and personally deliver it to your door if you do my pegaso headrace bearings. ;D
Still haven't touched the dam thing finally get the free time but been too ill to do them. >:(

It is a Italian bike, just squeeze another bit of tin foil in the gap ;)

A bit of reading for anyone interested. http://www.buckeyetriumphs.org/technical/Brakes/Fluid/Fluid.htm

Your getting as bad as Hairy ;)
Nothing wrong with Italian bikes.

Never seen you on one yet ;)

My Guzzi managed about 1000miles before springing a leak and the Aprilia managed about 300miles this year what more do you want . ;D

Enough said! You drop yourself in it every time, you come onto a Honda forum, and complain about how unreliable and expensive to fix your piles of Italian dung are, then whine if we take the piss! What do you expect????

I best not mention my Laverda Jota (or Lada Jota as a few mates call it) 8)
-
DOT 5 is hydrophobic.
I thought that was a fear of water :o

Lada120 gets it.
Hondas are great if you need to get to your destination. Italian bikes make the day all about them and make the day a little more interesting as your never to sure your day is going to go to plan.

Exactly - it does not absorb it! Hyrdroscopic on the other hand does attract water per "normal" brake fluid....

You do need to flush the system thoroughly as the two fluids are not mixable but you don't need to change the seals.
However if you happen to be rebuilding or reconditining the hydraulic system then that is obviously a good time to switch to silicone fluid should you wish to do so.

That's very true and wonderfully put Mr Green. Honda is ultra reliable and fun (old 400/4, 250RSA and CR750) but the Jota is a bruiser and is an assault on the senses. It has to be said the alloy castings on the Laverda are far superior to those of a Japanese bike. The Morini 350 Sport is also great fun and in my opinion better handling than my Triton I built 10 years ago. BUT.......the quality of the engineering on Honda's is far superior in my opinion and spares availability even for the older Honda's is much better, trying buying second hand tanks or sidepanels for Laverda's, crazy money and they are nearly always in Australia!
All the above said though, I'd never sell any of my bikes, they are all unique and all have a character of their own. Bikes are brilliant full stop ;D
Now back to the brake fluid thread....... :o
