Ls1 rear disc (from drum) conversion brake line help
Begginer doing this conversion and so close to finishing but need someone to explain how the thirdgen hard brake line connects to ls1 caliper? I wasnt given the caliper hoses so im wondering if i need these as the middle connection for the calipers to hard lines? Thanx for any help

Yes you need the proper flex lines. You will also have to tweak the factory bard lines since they will not be perfectly bent as is. They should be plenty long, just needing some bending to match up with the ls1 brackets

Thanx! Once i have the flex line does this connect as is or do i need a special fitting for the hard line? If so what size?

fittings are the same, you will just have to bend the lines some to make them work.
