I have a 2015 Vauxhall insignia SRI 2.0 CDti VX line. My brakes suddenly stopped working properly, the brake pedal went really hard and the car was struggling to stop. Tried to get it booked in but everyone saying it could be a couple of weeks before they can look at it. I decided that I will have ago at it, I've done brake pads and discs before. After watching loads of videos and reading up on YouTube I checked the servo first and discovered that this wasn't working, the brake pedal was not dropping slightly when starting the car. I replaced the servo and master cylinder and then bled the brakes but still no difference. The brake pedal is however dropping slightly when I start the car. I decided to then change the ABS Modulator pump and re bleed the brakes but still the brakes are very poor with a hard pedal.
Is there anything else I can try?

Ok. So I've now replaced my front brake pads and discs and then bled the front brakes. Still have the same problem. I've noticed some oil around the vacuum pump. Also I keep getting an oil pressure fault intermittently displaying. I've ordered a vacuum gauge tested which is coming tomorrow that should tell me if I'm getting enough suction from my Vacuum pump. There is just no brake assist at all.

Ok, I've just connected a Vacuum gauge tester and my readings are 27 inHP. I've checked what I should be getting and it should be between 16 and 25. So I'm getting more than what is expected the max shouldn't be more than 30. My head is wrecked now. Like I said I've got alot of oil around the pump but if this was a problem then surely my readings would be alot less, take alook at the pics.

I've tested the vacuum with the hose connected to the pump.

Is there anything else which could be stopping me from getting the assist for the brakes?

Ok, I've attached a video of the noise when you press the brake pedal. After reading more on the problem I have, everything is pointing towards the servo and master cylinder, even though I have replaced it with a used one the used one could also be faulty. Can you test this by disconnecting the brake lines out of the reservoir and then do a pressure test by putting a vacuum gauge on one of the outlets of the reservoir?
