The easiest way I find is... Disconnect the brake pipe going to the rear off the car,take this and use it ad your feed into your hydro,then flare the ends off a copper pipe and tread this into your feed out on your hydro and back into wear you took off the original pipe from the back,job done..ive always used this way and has worked perfect...you could buy braided lines but if you wanna do it cheap I fins this the easiest way and works perfect!
