It came time to change my brake pads today, and I managed to get the things apart and get the old pads off. I threw the tool on to back the piston back into it's cylinder so it would go over the new pads. Well, it won't back in. On other cars they might have been hard to push them back in, but they always went.



My dad says that there are certain ones that have to be twisted to get them back in (in which case he has a tool for it), either that or it's froze up. Since the ebrake works, I assume it's because they twist.



Can anyone verify that on an 85 GSL-SE?

rear disc brakes do twist in, very common on rear disc setups in order to keep pedal height

Thanks much, I'd never seen one like that before.

It does twist in. Local auto parts store sells the tool to twist it in. Just stick your socket wrench into the tool and turn it in.



OR, just open the brake bleeder and use a C-clamp to push it in. If it doesn't have pressure, it'll move in.

Picked up that tool today and got the brakes changed out in about 30 minutes. I really like how the calipers flip up, makes life easy.
