Subject: RE: Metal Break Lines


Hi. I think I found at last out how to send an answer to everybody, not
just to the original sender. Hopes that the solo one that got my mail on
the resourcefull @ people will send it back to me or redistribute it.
 
Ive changed rubber lines to metal (STEEL!!) on a lowbudget saloon racing
car. What will happen with rubber lines is that the fluid will get
extremely hot inside the caliper while braking hard. But everything is
fairly OK then. Then you release the brake, and the hot fluid will flow
back into the lines, that now, when unused will become hot, soft and
expanded. So far so good. But if you do a second panic brake less then
20 secs after the first one........  DONT TRY IT WITH RUBBER LINES!!
Next summer Im going for the alps... I will have steel lines then. An
alpine pass with just one hairpin is nothing for me.
