XK8 brake pressure loss to rear wheels??

[fast cars]

Hi I have a 1997 XK8 with 119k miles and it has just lost pressure to the rear wheels after having a brake line replaced (just small section for the front wheel)

Can anyone tell me what this could be due to?

Thanks

Sounds to me like they probably need bleeding again.

Was the pipe changed to the front calipers, or a section of the rear line?
