A problem in the system could very well cause fluid pressure to build as was described. Remember that the fluid forces the caliper piston out under pressure and when you release the pedal, that pressure is supposed to be relieved. It just doesn't magically disappear. Also, if you read the very first post, you would see that the problem happened BEFORE he replaced the calipers, so it is unlikely that any air was in the system at that time.

By the way, brakes will stick if the pins have corroded inside the caliper bracket and do not slide freely. You most likely will notice this first on your rear brakes as the caliper bolts bolt into the slider pins. The slider pins must move freely in the bracket and there should be no tears or dry rot on the boots. The front is slightly different as the bolts screw into the caliper and only slide into the bracket. (with the rubber boot protecting the exposed surface) PS, if you got bolts that require a torx T-25 or whatever size to remove them, get rid of them, and find the bolts that use a regular 6 point socket. You will find the work to be easier down the road when you don't strip out the torx socket hole on the pin. I have this issue and now when I replace my brakes, I take one pin out and have to rotate the caliper up and then off the bracket as the one pin is stripped out and I cannot loosen it. I suppose eventually I'll get a new caliper but it works perfect otherwise.

Agreed. The only rubber things that should have been used were the corrugated looking rubber boots. They are soft and pliable and go between the caliper and bracket to protect the surface of the bolt from corrosion so it will slide in the bracket. The pins should slide right into the caliper bracket with almost zero effort. Those two inch long rubber tubes were probably slid over the pins so that they would be protected from any corrosion or damage in shipping. If you pull the caliper and take the pads out, put the caliper back on, you should be able to slide it back and forth on the bracket with ease. That is a perfect test. If you cannot slide the pins easily in and out of the bracket, you have a problem with the bracket. This is a 10-15 minute job per wheel, so just do it asap. I don't think your hoses are the problem. It is that hard rubber tubing that you forced onto the pins.

I have an 04 with 17x,000 miles and you guys are scaring me. I can see needing some new tubing here and there, but the fact that the lines would be so corroded, hard to replace, and hidden through and behind things scares the crap out of me. Looks like I'll need to start accumulating some tools here and there and prepare for the eventuality.
