03 530i brakes locked up help please
03
bmw 530i, was driving it yesterday and the car started to viberate bad, then the car started to slow, it seems the
brakes all locked up, and the car slow and then would not move. i could hit the
gas and the car would not move at all. let it sit for a few hours went back to it and it drove about a mile and then the same thing happened again. a roll back came and got it, and when they winched it up on all 4 wheels were locked up. when we got to my place i was able to back it off and pull in spot but then locked up again. Any ideas of where to start looking, and what could be the problem? thanks for your help. This car has been nothing but problems, are these cars usually problematic? thanks

Can you describe the
lock up in detail? It is hard to believe the
brakes are locking up, they are a simple mechanism.
I also have a 2003 530i and I did the brakes yesterday in fact. Are you sure it is not an
engine problem?

when the
brakes start to lock, and i stop, i can press the
gas and the rear
tires will spin a little but it wont move. Also when the pulled it onto the roll back, it was in neutral and all 4
tires where locked up and dragged all the way up. but after it sat for 30 mins (i guess they cooled down) and it would move just a little more. hope this helps.

First thing first:
Jack each
wheel up (don't remove
tire), spin the tire, does it spin.
Otherwise what you described above may be a failing
transmission.

i dont think its the
transmission as the front wheels are locked up and the car is rear
wheel drive, so that would take the
transmission out of it. i know for a fact the front
wheels are locked up.

If it is truely locked
wheels, the only thing I can think of is the caliper seals seized.
But usually this happens one caliper at a time, not all 4.

Another thought is the Master
Cylinder.

Take off the
tires and play around with the
brakes. May be you can identify the problem.
Take off the
pads and reinstall them...

Pull your codes. It might be
ABS related.

If 'my' front wheels were locked up, the very first thing I would do is jack up the car, & spin the
wheels by hand.
Then, I'd remove the wheels, and spin the rotor by hand and take a good look at what's happening.
If I still needed information, I'd have a light person sit in the vehicle to gently press on the brakes as I spun the wheels
What happened when you did that?

Just one caveat: Not all ABS faults show an error code using a 'typical' run-of-the-mill code scanner.
One test of the ABS that 'might' work is simply to disconnect the
ABS control module
harness to see if that changes anything.

I don't disagree that it could be the master cylinder ... but wouldn't that usually affect all four
wheels?

I, for one, don't memorize Pcodes, especially since some are specific to the
engine computer model, version, & date.
What's the description for the P0600 fault code for your particular engine computer?
