<VV> Breaker Brake

[NicolCS at aol.com]

Wow, I'm sure glad to learn that the dozen or so vehicles that I've  
successfully converted to silicone brake fluid couldn't possibly work.  I'm  also 
delighted to know about the higher boiling point of DOT 5.1 so now I know I  can 
have this *useful* benefit of DOT 5 silicone and get back the beloved  
corrosion and paint-damage characteristics of the beloved DOT 3 fluid.
 
DOT 3 Benefits: Cheap, distributes moisture
DOT 3 Weaknesses: low boiling point, permits corrosion, damages paint
 
DOT 4 Benefits: Moderate price, distributes moisture, higher boiling  point
DOT 4 Weaknesses: permits corrosion, damages paint, some rubbers react to  
chemistry
 
DOT 5 Benefits: High boiling point, won't damage paint, dramatically  reduces 
corrosion
DOT 5 Weaknesses: High cost, coalesced water in system may boil,  entrained 
air may cause "spongy" pedal, system rubber should be new upon  conversion, 
 
DOT 5.1 (See DOT 4) + high boiling point
 
Pick which benefits are important to you and select accordingly.  For  me, 
the lack of paint damage and corrosion reduction leads me to DOT 5.   What's 
your choice?
