Passenger Front Brake Constantly Engaged

[funkymonkey]

I've got an R32 GTS4 with ABS, and I noticed that my front passenger brake was constantly engaged. Thinking this was due to a seized caliper or something I changed the caliper out, and while I was at it, fitted a new set of rotors and pads to both sides. Gave the brakes a bleed and fitted it all up. I didn't bleed the ABS system though.

The brake still refuses to let up once engaged on the passenger side. I'm trying to figure out a process of elimination to find out what's wrong. I don't get any ABS error codes from the ECU or lights on the dash.

Could it be:

something stuck in the line acting as a one way valve

faulty ABS

faulty line

or something else?

Has anyone had similar symptoms? What can be tried and fixed?

That's odd. If you open the bleeder on that caliper, it will loosen the brake if its a hydraulic problem. If it stays on, then the new caliper is suspect. Rebuilding calipers is pretty easy BTW.

I thought the first caliper was faulty so I put a replacement one in. Both work in one direction only, ie they clamp but don't release.
