Dr30 Rear Calipers - Pushing Piston Back

Hey guys.

I got a caliper here that I could do with a blown up diagram of.... But can't find anywhere.

My issue is that the piston won't return back, nor rotate (to screw back) so I can replace the pads.

Is this a common issue or am I just doing it wrong? I've put a lot of force on it, maybe not enough but I'm not too sure.

Tips, advice, pictures!

I tried to spin it with a pair of multigrips but couldn't get it to budge.

Its been sitting around for a while before I got to it, but it still had fluid draining from it when I got it, so it hasn't been entirely dry.

I'll make some more attempts but it may be a rebuild job...

Photos of the rear (handbrake section) would help. It's definitely a windback piston, some calipers do have a screw in the rear for winding back. Give the piston face a few taps with a hammer too, it helps to free them up alot of the time.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
