So long story short I bought a g6et and previous owner gave me a decent deal on xyz brakes fitted.
but once he installed them and bleed the front and rear with new fluid, started getting spongy brake pedal.
He replaced the master cylinder but that did not help and he got super busy and I had to get it towed on Friday from qld to nsw.
Have now got it in my garage finally, so figuring it out if I should replace the booster or try rebleed it myself and see if that was the issue
Was told it was braking fine with the stock brakes before upgrading to these.
no error codes showing on the torque app.
