Hi,
Is it normal to have several drops of brake fluid within the rubber caps on the brake nipples after a track day. I know the brake nipples are tight i dont want to over tighten them

The threads and seat can wear over time, brembo calipers suffer from this.
Usually caused by wear and tear of lots of brake bleeds and overtightening .

Take them out, clean up threads and seats then do a full brake bleed making sure not to overtighten, see how you get on.

Sometimes slacken off then retighten can stop it to.

If it still persists try new bleed nipples from AP

No probs Derek, worse case scenario is retap and new nipples.

Cheers, I'll go and but new ones hopefully not need to retap them , is there a way to check they are sealed properly I pushed the pedal multiple times after bleeding the last time to check for any leakage,

Other than that no. Just keep monitoring after driving.

When bleeding, clean all bleed nipples and rubber caps before installing caps.

I wouldn't worry unless you are certain there was no fluid there before hand - when you bleed the brakes you always leave some fluid in the top unless you manually clean it out.
