I would bleed the entire system. You might not think there is air in it, but there could be. Plus brake fluid absorbs water anyhow, so it could just be old to begin with.

Did you manage to resolve your problem as i have just changed my front brake pads and it is doing the exact same thing, before i changed them the braking was perfect apart from the "check brake linings" light came on the instrument panel, i changed one side then pumped the brakes and the pedal came up to pressure then i changed the other side pumped the pedal and the pressure came up again but then when i went to test the car the pedal went very spongey the brakes do work but they could be better !

I have the same issue..... I can brake but, the pedal is softer now than before I changed the pads.
I bled the system and performed the "Bedding" procedure and it still feels like my brakes are too soft.

Any help would be great guys!!!

The brakes work still even when they are on the floor.

Is the a problem? And what could it be.

I don't think there is air in the system as with the ignition off It would be soft.

Please let me know

RS - last summer i replaced all my rotors with stop tech rotors and new axxis delux pads.....and painted my calipers, etc. etc. ............with all of that said..yes the same thing happened to me. Bring to an indie and get power bled on a machine. once that is done ...well if they are a bit more soft ...then you have to live with it. Also...when car is off the pedal will be rock solid. So..for piece of mind, have an indie that you know and trust bleed those bad boys and take it from there......

Mine are a bit softer......but work pefectly fine! i thought with all the upgrades I was going to have this race car braking system that stopped on a dime...not the case!

I hope this helps!

If the rotors are warped you will never have a stiff pedal. The warped rotor will push the pads back into the caliper causing the calipers to need more fluid to clamp them down on the rotor again. Manys times it's more than the master cyclinder can give in one stroke, IE spongy brake pedal. When ever you put new pads on you should at least have the rotors refaced (very light cut) this way you'll find out if your rotors are warped. Also most shops won't cut them if they are marginal on thickness. It doesn't make sense to put new pads on worn rotors.

Richirich,
You should be stopping on a dime. If you have a spongy pedal I think you need to look further IE master cylinder or warped rotor

My X3 does this. I don't ever remember my E46 3.0i sport doing it so I took it in to the dealer. They claimed it was 'supposed to do that', and because of my disbelief, the service manager got the keys to 5 X3's in the used car area and I tried each of them and they all did it.

Exactly the symptoms you describe, pedal is rock solid until you turn the engine on, then holding the pedal down hard it will gradually sink to the stop. Just had the brake fluid done as its 2 years were up and thought that may have fixed it, but nope. Still doing it.

Must be something peculiar to the SUV's though as like I said, my E46 didn't do it

The brakes on my X5 are now fine i pumped the brake pedal up and blocked it with a piece of timber against the seat base and left it over night (this opens all the valves etc in the system and any air can travel back to the master cylinder, it works) and i ran the car and as the pads bedded in the brakes came back to normal. I think i have a wheel bearing going on the front n/s but i belive you need a press to do the job !
