Hi guys, I've read posts from people who have similar fails but never seen the solution ...
So, I have an 03 350z coupe and the brakes lock on after 5minutes of driving. ABS and 2 other fault lights illuminate. If I disconnect one plug on the abs pump, reconnect, start the car and accelerate, I feel a clunk around the brake pedal area and the brakes release only to play up again.
I have changed the ABS pump already, it didn't make a difference. I have a feeling that something is failing at operating temperature as the fault comes evry time after 5mins. Any suggestions ?
Thanks guys

Have you checked to see if it's throwing any codes?

Sounds like may be ABS/speed sensor.

I haven't been able to scan it as I can't drive it to a dealer. I don't overly want to get it towed there. I thought maybe a speed sensor, but it's something that occurs at operating temperature that is causing the fault I believe. I'm wondering whether it could be vacuum related, like some form of solenoid that opens at operating temperature..

Try going in the Brake and Suspension Tech area and searching threads.

Good luck!
