on the topic of brake lines



I called matco and Cleveland to get the low-down on brake line pressure and

here is the scoop:



the pressure of the brakes (matco) is .6 x gross wt divided by the number of

brakes (2) or about 500 psi.  the units are rated for a maximum pressure of

1750 psi, max use of 850 psi but the rep said you don't get much improvement

in braking after 800 psi. 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.
