maybe I am expecting too much....here's what I notice still with the new master and booster (ATE)
1. Three applications of the brake will turn the pedal hard...is this "normal" while driving at city speeds in that will 3 quick sucessions cause the pedal to become hard, until the vaccuum catches up and improves it in about 20-30 seconds.
2. The vaccuum connector at the door lock vaccuum connection reads -18 PSI and holds the vacccum steady while car off...I capped off the ACC vaccuum line and that seemed to help slightly (I stilll have some leaking ACC dashpots I believe, but would that affect brakes?)
3. Also, what fluid do you guys recommend in terms of fluid? I put DOT4 Valvoline Synthetic...I'm wondering if I'll have better performance and braking power by going with genuine mercedes fluid....
4. I did accidently introduce air during bleeding after changing the booster and master in the left front wheel bleeding. I believe I have got it all out with the power bleeder (bled all four wheels again RR, RL, RF, adn LF)....if there's residual air it would causing a sinking pedal adn not a hard pedal right?
