Passenger Front Brake Constantly Engaged

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.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
