    Stainless works best when everything is new. Trying to get SS flare to seal on an old seat can cause problems.

    If you're making your own, I recommend the Copper/Nickel line. It's very easy to work with for bending and flaring plus, it'll last as long as SS most likely. That line costs a bunch more but worth it, IMO.

    I got them to seal but it took some work. Tightened then loosened a few times. They eventually sealed. The bad part was it leaked on the paint and I was using Dot 3.

    As an aside, I saw an earlier comment showing 76-80 front brakes lines under a single PN. 76-77 front lines are not the same as those from mid 78-80. Routing is entirely different. Not sure which version Dantes is offering.

    1980 is different due to the calipers mounted toward the back of the rotor

    Great Point Kevin. So few people have your expertise in the uniqueness of the '80 as an F-body. So that would mean it uses the same lines as all the later M's and there's actually three different line sets for F's.

    My '79 has the rotors mounted to the rear of the rotors. Thought all years were that way.(?)

    That's still the early style caliper and hose. They changed the caliper bleeder location when they moved it and routed shorter lines to put the hoses behind the control arms. A real improvement. I'm inexperienced in '80 specific knowledge but knew the later M's are all that way.


    Early cars had the passenger side front line running along the bottom of the core support. They rerouted it across the firewall later and changed the driver side also, while keeping the same hoses and caliper configuration. Then they finally got smart and just shortened up the whole system.


    DCAspen, does the shorter system change the proportioning valve also? Or did that remain the same?

    Funny thing. I thought the earlier F bodies got the recall front brake hoses for routing but it appears the 80 had the issue???? 76-79 were recalled due to cracking. Hmmm.. So I`m kinda up in the air as to which is better?

    the front brake hose routing on the involved vehicles may allow interference between the hoses and the front tires during extreme turning angles.

    Special brake hose restraining straps will be installed on each involved vehicle to relocate both front hoses and ensure that adequate hose to tire clearance is maintained.
    Vehicle description: Passenger vehicles.system: Service brakes; brake hoses.consequences of defect: Abrasion resulting from such interference could causehose failure, loss of front braking capability and an accident.note: The instrument panel light provides warning of partial brake failure.
