My dad owns an Acura TL 2007 model. He has described to me an unusual problem but doesn't like computers too much so asked me to post this for him.

Over the last few months he has a strange behavior. He will wash his car and leave it in his garage clean for a few days. The next time he drives it, when he tries to back out of the garage the brakes feel like they are locked (almost like the emergency brake is on but it is not). He has to almost gun it to get it go in reverse. Once out of the garage, it still feels "locked-up" for a few hundred yards going forward until it seems to "free up". He drives it for weeks for no problem until he washes it and puts in the garage again for a few days.

Has anyone seen or heard of anything like this. Right now he has given it to his dealer to see if they can reproduce this and determine the problem.

I do not know, that seems to be a toughy, with a random outside factor. The piston caliper should be fine, and the pressure of your break fluid is maintaining, the only thing that seems to be reasonable is that your cylinder boot for the caliper may be damaged or got fold up in it so it isn't allowing it to properly retract. The only other factors are your master cylinder for your break fluid.

Has he had his brakes changed anytime recently?
Anything to do with brakes? caliper? brake lines?
how far down is his brake peddle go when he presses it? estimate by inches

C25 probably has the answer

No such thing should happen as "free up" as your drive a bit. The brakes need to be free, until they are engaged. Generally there is a leak or lack of pressure and you feel poor braking capabilities. However, this is the complete opposite which is and has to be related to your entire braking system.

Thanks for your reply. I'll have to ask him your questions. I'll pass on your comments to see if this helps him.

Who is C25?

This is kinda common and isn't really an ABS issue. Part of it has to do with the pad compound and the other is nature. Basically your dad has been putting the car away "wet" without really drying the brakes. So what happens is that a thin layer of surface rust will form on the rotor and depending on the metallic levels of your brake pad compound, on the surface of the pad where it meets the rotor. So, in essence, your pads have stuck to the rotor or seized itself to the rotor. I would suggest taking the car for a spin around the block after washing before putting the car away. That should cure it of any pad sticking issue.

Oh, and it's more prevalent if it was put away wet and parked with the hand brake up
