Reported cause
I had a similar issue and it turned out to be the brake booster and master cylinder.
Leading evidence: 'brake booster and master cylinder' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'brake booster and master cylinder' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Adjust free-play, i gave the nut about one turn' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I did manage to adjust the free-play, I gave the nut about one turn.

Today I removed the access covers in the frunk to observe the brake action and to check for obstruction but found no clues.

I may replace the master and booster but that's not the repair method I prefer, just throw parts at it hoping for a cure.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have a '99 with low miles, 60k, with a brake problem. Yesterday morning on backing out of the drive the brakes stayed engaged and nearly prevented the car from moving. Today I removed the access covers in the frunk to observe the brake action and to check for obstruction but found no clues. I had my wife start the car and apply and release the brakes and they were working normally. I may replace the master and booster but that's not the repair method I prefer, just throw parts at it hoping for a cure. Any ideas?
Before you search for a mechanical problem, did you wash the car then park it? Occasionally I've had the pads form rust between them and the rotors so bad that it took quite a jolt to get them broke free.
This has happened to me so many times. Wash car, pull into garage, Monday morning back up down the driveway and the pads and rotors are literally stuck together. One good brake application later and no problems.
I wish is were just the pads sticking. I did drive it a short distance with the brakes sticking. All four rotors were hot so they all were applied.I had not washed it.
I did manage to adjust the free-play, I gave the nut about one turn. I know that too having no free-play can cause the brakes to drag. Usually that only happens when things are hot. I'm going to test drive and just hope I don't get stuck with the brakes locked up!
I have an '02 and the same symptoms, been diagnosing 2+ weeks and 100+ miles. I release the brakes by bleeding off pressure at the ABS unit. You are the only other person to report this problem I have found.
Test drive went well. This may have been happening in a small way for some time and would explain the poor gas mileage. I'll get back in a few days, Bob
I had a similar issue and it turned out to be the brake booster and master cylinder. Water intrusion of the brake booster caused corrosion. Here's the link:

Good luck!
Yes please Bob, I have had this problem today of all four brakes not releasing the fluid back to reservoir. Where is the free play you talk about and how do I adjust it.
This is a source reference. Confirm exact model applicability in the original material.
