Soft brake pedal + errors :(

[bbrys]

Hi, yesterday after a bit harder braking a lot of errors came up on my dash and I have noticed that my brake pedal became soft.

When I start to push the brake gently, pedal is constantly going to the bottom and not braking well, I have to release it for a moment and once again press it. If I press it bit harder then the car brakes almost like normal.

Now, for a while I have this error on my dash but when I connect INPA, the error is not there and when I clear error history it won't dissapear:

Then, when I press brake hard, another errors are showing:

When I connect INPA, no errors are stored in the memory so I don't know what happened :?
After I restart the car, only one light is in the dash (the one from the first picture).

Does anybody know what is the reason of this? I have checked brake fluid level and it's full, have checked abs sensors in every wheel and all of them are connected.
Do you think ABS pump just said byebye to me?

I had part of that combination of error lights recently, the one within the Rev counter and one of the other two (can't recall which), was one of the brake pressure switches failed, which are located at the bottom of the master cylinder. Was a cheap (purchased from a breakers) and quick fix. No pedal issues with my situation though.

Did you check the errors on the brake module itself?

Either new pads or sensor required

...I think this is the most important bit. Seals in the master cylinder are leaking. Replace / refurb master cylinder before you do anything else.
