An poorly designed self adjusting automotive hydraulic clutch using 
regular brake fluid fails regularly. A test with a heavier viscosity fluid 
(Dextron ATF) solved all of the operational problems, but the chemical 
makeup attacked the rubber parts in the system. Looking for a fluid that 
will be heavier (like ATF) but will not attack rubber parts. High 
temperature resistance is not a requirement like when used in a braking 
system. To be used in a 15 year old automobile. There are still thousands 
of these cars on the road. Most of which have the same problem. This is 
very important to me, and I ask you to take my request seriously.
Thank you,
