brake pedal to the floor after new discs/pads/bleed

If the pedal sinks slowly to the floor I'd strongly suspect a problem with the master cylinder, probably aggravated by not using a pressure bleeder.

Pressure bleeding is fast, easy, safe and very effective at dealing with 'difficult' systems. For the home mechanic, the Gunsons Eezibleed is £20 from Halfords and works perfectly. I've had one for many years. The're great for fluid changes. I doubt that a professional unit is that expensive and I'm amazed that a commercial garage wouldn't use one.

I believe that bleeding in the traditional manner is no longer considered good practice.

with light pressure, similar to return spring the pedal doesn't sink. It requires more pressure.

It is strange though, just tried the car from cold, and now the pedal is firmer and pedal doesnt reach the stop as yesterday. it seems to be much closer to what I would consider normal 🤔.

Very confusing.... could the car being totally cold make a difference?

I'm going to be careful and monitor and consider bleeding myself or using a different garage. From what Ive read it now sounds like the master cylinder is okay and the likely cause is air in system or a minor leak somewhere I cant find... its odd
