Power steering vibration

[Gelf VXR]

Ive driven several hundred miles since replacing my headers which involved dropping the steering rack, which I had disconnected the hydraulic lines, I refilled and everything was ok after I thought the air had bleed thru. Last week I noticed some vibration when pulling into the drive. I turned steering full lock a few times and nothing. Today it did it again, I felt vibration when braking, now when parked stationary and I apply the brakes and turn the steering wheel there is a lot of vibration from the front area of the car, the cooler I think.

Do I need to have the system bleed, I read here about a procedure that applies a vacuum to the system?

I've checked all the clearances still there and bolts are all secured ok,

The vibration can be felt in the steering wheel, and rattling from the cooler, I think it's air or maybe the pump failing when I turn the steering wheel, but I don't understand why applying the brakes causes it?

A few threads on Ls2gto on this, I topped up fluid to the max level, left the cap off turned the steering wheel full lock a few times, it's better now, just a hint of vibration

I guess steering rack its got to come out now, leaking fluid everywhere, doesn't look like its any of the unions, must be from dropping the rack to get the headers out and back in again

Do you remember what torque you tightened to? I have received the part now and noticed it has a rubber o ring.

The torque setting is 0.3Nm which hardly anything at all, got both pipes now will get them swapped this weekend.

Here is the installation and air bleeding procedure in case anyone needs it.
