looking for any info on what psi brakes operate at, the powersteering, and tranny(auto). we got a new vendor for our hydro hoses and was wondering if it will hold the pressure it would be a lot cheaper for me to build my own versus buying the tubing and flaring it and trying to snake it thur the frame

Proof strength on the PS hoses and brakelines I build at work is 1500 psi min. Tranny lines I have not done, but I have heard 200 psi is acceptable.

FMVSS106 specifies that brake hoses must have a burst strenght of not less than 5000 psi and be able to withstand 4000 psi for two minutes without rupturing.

Doesn't sound like 1500 lb rated is good enough....

Burst strentgh is typically much higher than the rated pressure. Most DOT hose is rated at 1500 continuous.
