As I stated a couple of times-
I had the same car brake opeerating much, much better after I replaced all calipers.
I know also that pedal firmness can be better (even though it is no comparison with the German cars I have).

SocalSam is correct it is simply the braking power that counts not the absolute firmess ( I have a 996 Porsche and that brake is like a rock). I am not hung up with the absolute firmness of my T4R.
I think that the effort to get the car to a halt is just too much and I cannot drive faster at all due to this condition, it is not safe.

The incident on the highway when the alarm went off during fast driving was very alarming to me.

My only explanation for the alarm during driving is that this had to do with the fact that the motor/pump could not replenish the pressure level as I had to do 2 sudden brake pedal pushes and this triggered the alarm.

Can I ask: Who had a similar experience with their T4R- alarm going off on the road that went away after 15 seconds (no failure of the motor)?

This makes me very suspicious and therefore I am not giving up finding answers and solutions.

My plan is
1)rebuild the front calipers and then test drive, see what happens.
2) install a brand new accumulator and check in again.


How would you proceed?
