Question Pedal to the Floor (BRAKES)

Having an issue with my brakes.... I have to push the pedal pretty far down to have my car stop completely. I've noticed it for the last month or so, my brakes and rotors are still good just passed inspection. I recently moved to Philly and have yet to take my car in for service at the Lexus Stealership and I don't know shops to check it out. I also don't have any tools at my apt. here. My IS 250 is a 2007 and I have 88,000 miles its still under my extended warranty. I think the Lexus dealership will charge me an arm and leg to look into the issue...

I checked my brake fluid still full
Brakes and Rotors are still good
Checked front brake lines so visible leaks

Anyone have any ideas?

There could possibly be air in your brakes lines

This is dangerous. I would go the the dealer to have it fixed asap over anything else.

Could be air in the brake fluid system, Master Cylinder goes out/leak, or seized caliper pins.

I agree with everyone else. If you've done all you've listed right, then it definately could be a Master Cylinder issue. When did you last change your brake fluid? You're coming up on the next change BTW.

funny how people call it stealerships, yet go to them for service anyways. dealership techs and advisors only "recommend" you do the services, they don't force you to

well **** if lexus is gonna fix it for free, take it to em!

what color is your fluid?
if its dark, i would replace it, hell i would replace it anyways.
and then bleed the system.
and if that doesnt help then you might need to the BMC
rebuilt (replace internal parts.) rebuilding is cheaper
than replacing but it accomplishes the same thing.

It sounds like its your master Cylinder, get it in to a shop ASAP before you lose braking power

Sounds like air in the system or the seals in the master cylinder has gone bad.

You should check your rear calipers. Most likely its seized. Same exact thing happened to me. I could not get them unseized...rusted solid. Ended up replacing the calipers, rotors and pads and now the pedal is much tighter and does not have to travel so far to engage.

BTW, you don't have to replace the pads and rotors...mine were just due for a change anyways.

Sorry it took so long to update, well it happened to be both rearcalipers were seized. $800 it cost me and my hands were tied because I just moved and have none of my tools here. Funny thing is this was 3 weeks ago and my pedal again is once again to the floor.

You think they've seized again?

I dunno it feels like it, I'm taking it in tonight. When they replaced the rear calipers they told me they would replace the slider pins and well. When I got the car back I noticed they didn't replace the pins because they still have red paint on them from when I painted them. I called to complain about it but I was told they rebuilt them. Its a pin wtf, I spent $800 already I would have gladly paid a little more to get the job done right.
