Depends where its gone, they normally go near the rear axle n next to the petrol tank which is a pain to get to
a roll of pipe isnt bad at about 20/30 quid
and a flairing tools not bad either.
you can get the ends from local auto factors aswell
but it is a major saftey feature so if you can afford to id get it in a garage, I had front to back and a few little 1s at the rear for £100
some auto factors will make you pipes up if you take yours up to match them to.
Then refit and bleed up.
