Hey everyone, long time since my last post. Ive been having some trouble with installing my rear brakes. I bought all new rotors and pads all around on my 96 cobra... even bought new caliper brackets for the back since i found out one of the pins was frozen. Ive now been having trouble with the piston on one of the back brakes. It just wont seem to push in all the way. View attachment 377204 I've tried using that little cube (sucks), and just went to autozone to rent the better tool. Still wont go in further. It is honestly about a 1/16 of an inch of difference and it would go on wonderfully. Im not the most mechanically versed, so please go easy on me. Im mostly self taught (which is not the greatest to say the least).
The E-Brake is off. The cap to the brake fluid is off, as Ive heard it relieves some pressure.
Am I right to assume that if this piston screws in, that it must have a stopping point and wont just keep spinning? It pushes out, as Ive loosened them and it goes fairly nicely.
Im stumped View attachment 377205 .Any help here would be mostly appreciated
Thanks!
p.s. i did a couple searches, got close to what i needed, but still not quite there. Also, Front pads are Carbotech Bobcats, and the backs (unforunately are from Autozone, Duralast. all my local dealerships are out of pads for the cobra)
 
+1 new calipers. Just to make sure you know...the rear calipers must have the pistons ROTATED in, not just compressed in. If this doesn't work, then the calipers are seized. You can open up the bleeder valves on the calipers also when compressing the pistons back in, this will guarantee it's not a pressurization issue.
 
My next door neighbor owns a brake shop and helped me with mine when I had the same problem. After we finally managed to get it retracted, be told me that more than half of the rear Cobra calipers he deals with have to be replaced.
