Spongy Brakes - 89 535i
New Brembo rotors and pads all around 4k ago. I do not know the history of the calibers, master cylinder or servo since I bought the car in 2006.
Brake fuild flushed last Fall.
No brake warning light.
Pedal travel is about 4 inches and distance from the firewall is 3 inches approximately. Just feels weird.
Searched around in the archives but didn't find anything similar.
Thoughts?

is it soft and seems to require a lot of pressure? Mine is similar after Ate rotors and Raybestos Qs ceramics. Been so for about 25,000 miles for the front. Rear rotors/pads this year did not change anything.

Not actually a lot foot pressure per se, it just the pedal travel distance seems excessive. The braking distance seems a tad longer. Feels like I'm almost clutching :>

make sure that all of the calipers have their spring clips inplace, they can be seen though the holes in the wheel, if they are missing the caliper can flex away from the carrier, this is on all cars with single piston calipers, on cars with multi piston calipers (pistons on both sides of the rotors) one piston or one side can stick and the other side still works, this will eventually start flexing the rotor more and more as it wears the pads on the dead side

mine has a lot of travel as well. Pretty sure, I have all the springs as winfred states. Even so, I will check for caliper travel.

ditto. If that works but it happens again, its probably time for a new master cylinder.
