Mark Davis: Thank you for your help, BIG time. Main thing I got is turn and push, not turn, not push. thanks again.
Gary Williams: Geezus! Now I see this. Just finished replacing the rear rotors (discs) on a 94 Cutlass Supreme. After about an hour of trying to compress the 'piston' with assorted clamps and curse words, I wondered what the purpose of those notches could be other than to rotate it. Sure enuff....
Nick Benjamin: THanks for this Brian.I hope I didn't damage the piston trying to compress it with a c-clamp
Juan Casero: Cool video Brian. I have been doing my own brake pad changes since I was 16 years old about 30 years ago now. All the piston calipers I have ever had were the old design that did not use this new fangled screw in piston method. I have two simple OEM hand wind piston caliper pushers that I have been using for years and they served me well. But they would not work on those new caliper designs. I have yet to encounter one of those but I went ahead and purchased a Sunex master brake caliper set from Amazon today in anticipation that I will need it eventually. So I went digging around youtube looking for videos about these new piston caliper designs and I found yours. Thanks for posting. It cleared up many of the questions I had.
Don Komos: I am having problem with compressing 2011 Audi Avant rear brake piston using the autozone caliper compressor for spiral pistons. Would you suggest releasing some brake fluid @ the caliper?
Raul Morales: My piston its stuck cant twist it, what can i do?
Zackary Fedorovich: I used channel locks and elbow grease....Depressed the Subaru caliper in about a minute. No fancy tools needed ;)
jeffrey r: do you need to crack open the bleeder valve before you collapse the rear piston?
Gary Farris: You can use Channel Locks also. Turn while pushing down at the same time...say it with me.. turn and push down. Very good now carry on.
