I tested this on the bench before installing and no noises. After installing it makes this clunking noises when pedal is pushed in. It feels like it could be catching the spring or something like that.
Do any of you have any suggestions what it could be.
Pedal box is not fully secured. Just held in place with a few fixings.
Brake transfer bar is not been adjusted. Pedal position looks close to where it should be.
Clio servo noise.

Not sure if it will make any difference but have you tried it with the master cylinder and spacer fitted?

Not sure, reggid, what's the booster diameter?
Jake, where would the spacer go? What do you mean? The master cylinder is fitted, full pedal box.

Copied from link below.
Because of the physical bulk of the M5x, you're not going to have room for your standard brake servo. For that purpose, you need to find a smaller unit that doesn't compromise on braking assistance. While the original swap guides called for the use of a Golf servo, these components are now approaching over 20 years of active duty, so we recommend upgrading to a Renault Clio servo from any car from 2001 onwards (with plastic wings).
The servo may need a slight adjustment - some do, some don't. The trouble is that the rod from the servo to the master cylinder often isn't long enough to make full contact. This leads to a high brake pedal, and binding brakes. While the rod can be twisted to adjust its length, sometimes not enough length is offered, or not enough thread is left on the rod to ensure a firm grip with the servo; this leads to the threads stripping and ruining the servo.
If you find yourself in this scenario, you may just need a spacer. A small bullet of steel up to 20mm in length can be slotted into the receiving end of the master cylinder. That way, the incoming rod from the servo doesn't have to penetrate so far into the master cylinder, and can therefore be screwed down tightly in place and secured with threadlock.

If it was me i would fit brake master cylinder to servo and fully secure the pedal box Then adjust the brake bar if needed and see if that sorts the problem your having atm.
2/3 down the link will show you where the spacers goes.
