Hi,
I am new to the forum and need some help .
Have owned the car for over two years but around 6 weeks ago the brakes went spongey and totaly failed after two days.( no external leaks )

I diagnosed the problem to the master cylinder which I replaced and changed all the fluid.

The new cylinder lasted around a week before the brakes went spongey again. Tried bleeding the system but no air in it.

I returned the new cylinder and had to buy yet another and await test to the returned unit (still waiting ).

The third cylinder now seems to be failing after being fitted for a month.

What is happening?

Has anyone experienced the same promlem ?:bang:
