Brake Question

[noog99]

Hey, I was wondering if you guys had an explanation of this. Let me explain.

Rotors were warped and they were a few years old anyways so this past weekend we changed the front rotors and pads, without any problems. Finished up and took it for a drive, and noticed the pedal felt spongy. So we bled the brakes...drove it some more but it stayed the same. The car stops fine, but once it comes to a stop I can push the pedal to the ground. That's the strange thing. I don't know if it was doing this before changing the brakes, it was only something I checked after changing everything.

Anyways, any suggestions? Bleed the brakes again? Master cylinder going bad? Thanks for any help, this site has been a life saver.

You could try to bleed the brakes again, but its probably a bad master cylinder. I know when i first put my brakes on they did not feel very good for about 20 miles or so, but I was never able to push the petal to the floor.

Bad master cylinder. Had the exact same thing happen. Mine was caused because I forgot to loosen the lid of the old master cylinder before compressing the caliper pistons.

thats not good news for me either then because i can do the same thing. It doesnt bother me though. as long as my car stops it will do.

We were thinking it might be a bad master cylinder, although I am 99.9% positive that we took off the cap before compressing the piston, so while I don't think it's from that, it could be I guess.

Thanks for the help, now I just have to figure out how hard it is to change the master cylinder.
