You need a special tool kit for the rear calipers not only for cadillacs with rear disc brakes, but for most vehicles with rear disc brakes. This tool turns the piston using the slots located on the piston. Note: when finished, be sure one of the slots on the caliper piston aligns with the bump on the back of the disc brake pad. Also double check that you haven't knocked off the electrical connector located in back of the rear wheel bearing as the "ABS" light will come on.
One of the parts in the piston are the piston head,
I had the same problem on my 98 eldo for a while. The electrical connection on yours(as was mine) is lose. I found the connector was not making good contact so I simply wrapped the unpluged portion of the connector with electrical tape to make it a tight fit. You can test your motor by take wire leads from the connector to the actual motor but be very careful you dont test it for too long or your latch piston will pop off.
A bent engine piston is a reference to the piston rod. The piston cannot be bent, but the piston rod can be bent.
The driving force action on the piston is called piston effort.In other words the net resultant of all the other forces acting on the piston is called piston effort.
The piston rings create a seal between the piston and the cylinder wall.
There is the penis, the testicles, the scrotum, the prostate, the sperm duct etc.
A piston seal is a gasket designed to keep fluid from leaking around the piston. Piston seals are commonly used in brake calipers.
The piston doesn't twist it's way out. There is a ratchet screw adjustment that takes up the slack behind the piston. Screwing the piston back in resets the adjustment.
It is a spring metal sleeve that goes over a piston to compress the rings so that the piston can be install in the motor. It tightens down on the piston, forcing the rings into the grooves in the piston then you tap it into the cylinder.
It connects the piston to whatever the design calls for the piston to push or pull on. In a combustion engine, the piston rod connects the piston to the crankshaft, turning linear reciprocating motion into rotary motion.
A larger piston skirt to cylinder wall contact raises piston cooling. With turbo motors, they have piston oilers, they spray oil on the underside of the pistons, cooling the piston /crown.
