Titolo: Grimeca sistema 11

Salve, conoscete i freni Grimeca Sistema 11?
Nuovo e ottimo freno per freeride impegnativo e dowhill, praticamente si
tratta del meraviglioso sistema 8 soltanto che è stato maggiorato.
Ne ho un po' di coppie nuove inscatolate e le vendo a £ 550.000 (freno
anteriore, posteriore e relativi dischi, 180 anteriore e 160 posteriore).
Se vi possono interessare scrivetemi in questo group e lasciatemi la vostra
mail per un contatto.
Grazie e ciao!
Michele

 mail per un contatto.
Non ti sembra di esagerare???
Passi la pubblicità, ma "scrivetemi su questo gruppo"... forse è eccessivo!!!

Si in effetti esagera giusto un cicinin!!
PS. Mi vendi un disco anteriore da 180mm?
PPS.  Che faccia di m...a che ho!!!!

OK OK!! Ma per il disco da 180mm?

tratta del meraviglioso sistema 8 soltanto che è stato maggiorato.
dove e' stato maggiorato? solo il diametro del disco anteriore o ci
sono altre modifiche su pistoncini e tubazioni?
se fai downhill lunghe ti consiglio di provare l'olio dot5.1, ha un
punto di ebollizione piu' elevato. lo hai mai provato? in caso di
problemi di surriscaldamento al posteriore puo' essere una soluzione
interessante ed economica.

Beh, allora.... ok!!
Pensavo fossi un negoziante che cercava nuovisbocchi!!! :oPPPP

Eh EH Eh !!!  Anche io ho appena fatto spurgare il mio impianto Grimeca con
il Dot %!!  Funge davvero bene!!

il Dot 5!!  Funge davvero bene!!
il dot5.1 o il dot5? il 5 ha una base diversa rispetto a quello
montato di serie (e non e' mischiabile con dot 3, 4 o 5.1) ; non ho
idea se cio' possa creare problemi all'impianto pero' nel dubbio mi
informerei. 
nel caso ti interessasse l'argomento ti incollo sotto alcune notizie
(in inglese)

DOT 3: This brake fluid has a glycol base. It is clear or light amber 
in color. Its dry boiling point is 401░ minimum and wet boiling point 
of 284░ minimum. It will absorb 1 to 2 percent of water per year 
depending on climate and operating conditions. It is used in most 
domestic cars and light trucks in normal driving. It does not require 
cleaning the system and it can be mixed with DOT 4 and DOT 5.1 without
damage to the system. The problem with it is that it absorbs moisture 
out of the air and thereby reduces its boiling point. It can also 
damage the paint on a vehicle. 
DOT 4: This brake fluid has a borate ester base. It is clear or light 
amber in color. Its dry boiling point is 446░ minimum and wet boiling 
point of 311░ minimum. It is used in many European cars; also for 
vehicles in high-altitude, towing, or high-speed braking situations,
or 
ABS systems. It does not require cleaning the system and it can be 
mixed with DOT 3 without damage to the system. The problem with it is 
that it absorbs moisture out of the air and thereby reduces its
boiling 
point. It can also damage the paint on a vehicle. 
DOT 5: This brake fluid generally has a silicone base. It is violet in
color. Its dry boiling point is 500░ minimum and has no wet boiling 
point in federal DOT 5 specifications. It is used in heavy brake 
applications, and good for weekend, antique, or collector cars that
sit 
for long periods and are never driven far. It does not mix with DOT 3,
DOT 4, or DOT 5.1. It will not absorb water and will not damage the 
paint on a vehicle. It is also compatible with most rubber
formulations.
 The problem with it is that it may easily get air bubbles into the 
 system which are nearly impossible to remove, giving poor pedal feel.
 It is unsuitable for racing due to compressibility under high 
 temperatures. If as little as one drop of water enters the fluid, 
 severe localized corrosion, freezing, or gassing may occur. This can 
 happen because water is heavier and not mixable with silicone fluids.
 It is unsuitable for ABS. 
DOT 5.1: This brake fluid has a borate ester base. It is clear or
light 
amber in color. Its dry boiling point is 500░ minimum and wet boiling 
point of 356░ minimum. It is used in severe-duty vehicles such as 
fleets and delivery trucks; towing vehicles, and race cars. It can be 
mixed with DOT 3 or DOT 4 without damage to the system. It maintains 
higher boiling point than DOT 3 or DOT 4 fluids due to its higher 
borate ester content. It is excellent for severe duty applications.
The 
problem with it is that it costs more than other fluids and there is 
limited availability. It also absorbs moisture out of the air and 
thereby reduces its boiling point. It can also damage the paint on a 
vehicle.
