Was How not to juggle rotors - now is brake fluid advice..lol ;-)

[Equus]

Just a FYI
if you wanna juggle brake disk rotors, because you get that juggling itch, make sure to look for
loose metal shrapnel on the edges. If you don't, you can get a nice cut on your finger and hand from it.

This message has been brought to you today from experiance. Thank you.
Carry on

Hope your cut is not too bad Elaine, and you heel quickly.

I've got a post in the 1-800-cafe-help section on Changing from Dot 5 to Dot 4 brake fluids.
Any wisdom from a Motorcycle Mechanic?

LOL thanks finger is better today..

I am only a Mechanic in training still... just begining (sp?) my apprenticeship..but, I am happy to help if i can.
What the school has taught us so far, please feel free to correct me if I get something wrong.

Main Object of the braking system on motorcycles is to convert kinetic energy into heat. With that in mind..

Brake Fluids:
Requirements:
High boiling point
Low Freezing point
Resist Aereation (No air pockets)
No Evaporation
Lubercate
Be compatible with rubber and metalic componets.
Maintain rate of expansion and contraction.

Types of Brake Fluid: (Dot = Department of Transportation)
Dot 3 + 4 - Glycol base-Polyalkylene
Dot 5 - Silicone base with Polylmethysiloxanes
Dot 5.1 - Glycol
HSMO - Hydraulic System Mineral Oil

Dot 3+4
Both fluids are compatible, but you really should not mix
color from clear amber to brown
water soluble
Is compatible to rubber and will blend well together.
Hydroscopic (absorbs moisture)
Disadvantage: Dissolves paint on bikes.

Dot 5
color purple to blue or voilet
High boiling point
Non reactive - Inert
Disadvantages: Not Hydroscopic (does not absorb moisture -
will allow water into calipers - spongy feel to lever)
Expensive
Ok if spilled on paint ?? not sure..on this point.
Not compatable with other brake fluids DO NOT MIX

Dot 5.1 - sorry I don't have a lot of info on dot 5.1
color red??
Glycol based like dot 3+4 types
not silicone based

HSMO: - not too much info on this type sorry.

Mineral oil contaminatoin (most oils are mineral) used in brake systems will cause severe swelling of all rubber parts and must be replaced.

Side stuff:
FYI: The average braking system absorbs about 2% moisture a year. This reduces the boiling point of the brake fluid.
Always use fluid from a new sealed container (less moisture content than if you have one open on the shelf) All brake fluids once open will absorb moisture.
Change/Flush brake fluid every 2 years - moisture reduces the boiling point of brake fluid by 50% with appox a 4% contanimation rate.
When in doubt flush.

ALWAYS a good idea to flush...makes it better in all ways concerned.

And make sure you put the seat down... especially in a house with 2 women

and wash you hands after too, please.
thanks

: LOL ^^^ very funny you 2

Some more added bits: The Dot designations specify the brake fluid's ability to withstand heat without boiling.
Boiling brake fluid will lead to drastic loss of braking force due to the air bubbles that form within the system. The greater the Dot number the higher the boiling point.

Although Dot 3 and Dot 4 are made with the same chemical base, they should not be mixed.

Most important: Your bikes service manual will have the correct Dot fluid to use.

Hmmm....kinda sounds like the Equus Service Centre will be opening soon, book your appointments early. ;D

Looks good too! Now your in business Equus ... LOL

Just try to ignore its a harley parked out front ... lets say its a Vincent Black Shadow.

Hey that is really great! I like it! Great imagination.. I like bikes lol no worries about the Harley
