does any body know how to depress the piston into its bore on a 1997 cadillac deville cause I use a C-clamp on mine its stif and I disconected the brake hose, detatch the parking brake from the lever its stillstif can I get some help please?

 

The C Clamp is how I always have done this. Could be your's is siezed and the caliper needs servicing.

 

i belive you have to screw the pistons back in, there should be two notches cut into the pistons, and there is a tool (brake cube) that will fit into these and tighten them in, it takes quite a few turns to get them all the way back in

 

thanks for the help katzmanz and stsscott, yea there is 2 notches cut into the piston and there,s a tool huh thanks for the help

 

the C-CLAMP works well in the front calipers but not in the rear calipers.
at least not in the Allanté. no amount of pressing will move the piston.

for the REAR calipers, i got a little spanner wrench type of tool to retract the
rear pistons, tool # K-D 3163, which is a little metal cube that
attaches to a 3/8" drive and has lugs that fit into the slots on the pistons.

the tool is used in the Allanté, dont know what other Cadillacs it fits.

lol

 

Yeah, I have the same tool, and am not too thrilled about it. The bow-tie shaped notches are too shallow, and when turning the cube with a simple 3/8" socket wrench, it often slips and I bust my knuckles. Usually, I have to hold the caliper with one hand and struggle turning the cube with the other. Maybe there are better tools out there, but since I do this rather infrequently, so far haven't botherd with getting one.
