Do you mean your brakes? If so when was the last time your brake fluid was flushed and refilled?
Brake fluid over time absorbs water and under some circumstances can boil and give symptoms similar to what you described. Once it cools off it will appear to be fine.

if you had brakes checked did they mention anything? Did they use a test strip in the fluid? Is the brake fluid low , discolored or smell burnt?

my suggestion is have fluid flushed and replaced. This will also ensure no air in system which can also cause issues you described. But if checked by a competent mechanic then that is unlikely.

Being at max does not indicate it has no water, or no air in the system, and it is not contaminated. Someone could have just added fluid to it. If they added a different DOT rated fluid and it is not compatible with existing fluid that can also cause issue you indicated. Has it ever been flushed and refilled since you have owned the car? If not have it done ASAP.

If ABS module failure( it is not "good"), was there a light on the dash or did they mention a code? If the module failed did they suggest replacing it? Brakes are very important and if you have any problem with Brakes it puts life at risk, Not just you but everyone on the road with you.

And it is Brakes Not Breaks or Breacks.

If this happened to my car, it would be either at an ASE(Automotive Service Excellence( https://www.ase.com/Home.aspx)) certified(in brakes) mechanic or a dealer and would not be driven till the issue was fully diagnosed and certified fixed. I am not sure if there is ASE in the UK but I presume something similar exists.

But as all have seen me type many times your car, your choice , your money & most of all your life!

They said they did alot of tests on the hidraulic system and the breaks itself and didnt found nothing but based on what i describe to them they told me that there might be a problem with the abs modul pump and i should take it down and sent it to bee checked and replaced if needed , also i just tested the car again on an empty road and the same thing hapened again wen i pres the breaks real hard , the fluid hasn’t been replaced since i own the car , i remember i had a batery problem as the alarm was going on by itself and was draining the battery and wen i wated to start the car it was showing me an abs sign , i thought it was because of empty batery so i disconected that cable from the hood , after that i didnt had any batery problems but im just thinking if it was something to do with the abs system aswell , so i will stop driving it and get it cheked again

Battery failure will turn on erroneous error lights. Go to a different shop tell them it has happened 2 times. Do not mention anything else the first shop said or did. At minimum have brake system flushed and filled. Obviously the first shop is not skilled if they did a bunch of tests and system still fails.

This sounds like the proper operation of the ABS system, aside from the loss of braking power.

12v Battery failures cause various problems with the CRZ that don't fit the profile of a dead battery in more traditional cars you may be used to.

All that said, take your car to a brake shop and have the brake fluid replaced. Unless you did it within the last year, you need new brake fluid anyway.

This is my concern. The pulsations are normal the complete loss of braking is not. Unsafe to drive till diagnosed and repaired.
Is it loss of braking when the ABS cycles, or is it loss of traction when the ABS needs to cycle though? Last time I drove on glare ice, the ABS cycled, and the pedal went to the floor and the car didn't slow down - but it wasn't a loss of braking.

Depending on conditions I guess but first shop saying potential ABS module would concern me but it may just be the way it was explained.
If it were me I would take it to a big obstruction free dry sand free parking lot and do some hard (locked) braking testing to see if it was the conditions or really a brake failure.
