I noticed that the brake pedal has quite a lot of travel after you stop. When stopping all is normal, good braking action and comes to a stop completely. However, once completely stopped you can push the brake pedal down an inch or more. I checked other forums and this complaint is on most of them.
You cannot pump the brakes up. So, I don't think the system has any air in it. My 2006 Frontier only has 2200 miles. I think it has been this way since new. I just happened to notice it recently.
Does anyone else have this problem? Have you had it checked out by the dealer? I almost believe it is a normal condition.
Thanks for your responses.

We also have a 2005 GMC Envoy. I tried the same thing on it today. After coming to a complete stop you can push the brake pedal down another 1" to 2" inches. This must be something to do with the power booster unit, because after you shut off the engine and cycle the brake pedal until all the power assist has been bled off, the brake is solid as a rock. I think this is a normal condition.

westex39;

... Some modern vehicles come from the factory with vacuum pumps to assist the vacuum operated power brakes. It is probably to cure that issue.

Have a good one, and CUL.. Don S..

I know this is an old post but did you resolve the problem?

My brakes on my 05 Frontier were rock hard I put new front pads on it the other day and after that the pedal has been spongy. I never opened a line or bleeder to let air in the system. I went ahead a power bleed the whole brake system to get fresh fluids in and any air out. But it didn't help the pedal feel any better. I now have to press the pedal down half way to stop and I can still press it to the floor when at a stop light.
