I replaced the rotors on my C6 last night and the pedal is now on the floor. bleeders were never touched, just simply pulled off the rotors and replaced with cross drilled units.

was giving me warnings for checking the stability system.
any insight would be great.

I did search the forum but did not see anything describing the same problem, but I apologize if this is a double post.

Thanks

Pump the pedal a few times. That's all you need to do.

maybe,,,,,,, you have to pump the pads back into contact with the rotors if you pushed the Pistons into the calipers to fit the rotors.

and OP, I would also look to see if you pushed brake fluid out of the reservoir. When you push the pads back, it forces fluid back into the reservoir under the hood. When you do all 4 rotors, and really puch back the pads to install new rotors, it's easy to flood it out of the reservoir.......

If you don't know to pump your brakes up after working on them, you shouldn't be working on brakes.

Did you only push the brake pedal down once?

pumped brakes, now pedal is STUCK at the floor. Should of made that a little clearer, sorry.
I know how to pump brakes.
I also didn't even need to push the caliper pistons in, just put the new rotors on.

Did you do it with the car running? Did you try pulling the pedal back up by hand? It should come up. Then pump it half way a few times to pump up the caliper pistons back into position. If you can't get the pedal to come off the floor you may need to disconnect the vacuum line going into the booster.

Have you tried reaching down with your hand and pulling the pedal back up? Or working the pedal with your hand?

Here is a thread - post #10 - where pushing the pedal to the floor damaged the master cylinder seals (evidently) so be careful.

I even got my foot under the pedal and couldnt pull it up. don't know what the heck is going on.
never experienced this before on any car

No way you can replace an old rotor with a new one without pushing in the piston. Even if you used the old pads you could not do this, and if you used the old pads it would be a mistake for sure.

If you don't crack the bleeders and you didn't push the pistons back in....then how much should you have to pump the brakes since the system wasn't "disturbed"...so-to-speak ?....

iroc07

exactly
I don't understand how this happens

NiteriderFRC

Something is off with your story. Did you do all the rotors? Fronts or rears? Did you kink a brake line?? <--- that would be hard to do...Check the reservoir, un cap it and check the level...Hell do all the possible basic diagnostics first and get back to us!

iroc07

just fronts

I must say that I have never heard of this 'pedal staying on the floor' before when it applies to brakes. The only thing that I can think of is that some part of the system is jammed and not allowing the return of fluid into the master cylinder. Just thinking out loud here...

jimmymac25

New rotors are thicker that old rotors, besides the pistons will have to move some, just to allow the calipers to slide off. If you didn't change pads, and just did the rotors, it's a half a$$ job. But the pistons will still move in their bores some to allow you to remove and replace the calipers.

iroc07

they are stillen cross drilled rotors. has anyone had any issues with these before.

iroc07

I was able to just pull the caliper off of the rotor with minimal effort.
