Installing new Shimano pre bled brakes question

I've just bought a new set of pre bled SLX brakes. Hoses are attached to the calliper but not the lever which is capped. I'm not shortening the hoses at this point as bars and stem may well be changing. The question I have is do I need a new olive and insert. I imagine not, it appears that the insert is fitted and I assume the unused olive is behind the cap on the lever. I'd just like confirmation I'm getting this right before I start.

Thanks

Yeh the olive will already be inside the lever so push it in nice and hard and tighten it up.

I can't imagine that a brake, not already fully assembled wouldn't need a bleed. Even if both parts are filled, at least do a lever bleed. If that doesn't work, then do a full bleed, just to be sure.

I've installed hundreds of those brakes and swapped (L/R) hundreds more. I've needed a subsequent bleed only 2 or 3 times.

I'll do a lever bleed once I've got everything else done, brakes are on and working. Front feels good while the back feels like it will need a lever bleed. Very little fluid escaped while fitting.

Now just fighting the internal gear cable routing. There is a thin liner in the frame, On One Whippet, but it's moving and crushing up against the outer as it enters the frame. Shifter works at first then stops as the friction increases. I've got some full length outer arriving today so I'm going to try routing that right through the frame.

Ok, sounds good then. I have only ever bought fully assembled ones or ones not assembled at all. On maguras, I have always done a lever bleed after a hose shorten, L/R etc.
