I've just put new disks and pads on the rear of my 93 WRX (courtesy of Ian Godney) and HEL brake hoses too.
Just been to bleed them and I've got a slight weep from the pipe that connects to the HEL pipe. It coming from the joint of the actual pipe and threaded part.
I need a new one but where does it go when it disappears under the car?
Does it run all the way up to the front?

 

I think it probably goes inside the car up towards the front of the car. It does on my bugeye anyway.
