Cleveland's was about the same. their setup has a max pressure of 600 psi. with this in mind, I wonder if the aeroquip 666-3 line isn't a good choice for our brake setup. it's operating pressure is 1500 psi and it's max is 2-3 times that. it is very tough and covered with a stainless braid. best of all it has a Teflon core which will take high temperatures and has a nearly infinite shelf life. it is also cheaper than the DH hose. the -3 is small enough (I think) to minimize mushy brake feel. any responses the these ideas on this would be appreciated.
