Best to just buy a rebuilt caliper complete. Cost is about 20 bucks or so.
How do you compress the rear break caliper, pistons on a 2002 Sierra ?

If your timing belt were to break while the engine is operating, the camshafts would be out of time with the crankshaft. This 'out of time' would cause the valves to open at incorrect times in regard to the crankshaft/pistons. This break in the timing belt could cause valves to bend or break as well as damage the head itself; pistons could also become damaged in the process.
I change mine every 8 yrs, just to be on the safe side, because if it were to break, the pistons will slam into the valves bending them and causing a MAJOR repair bill.
on some engine designs when the timing slips or is wrong the valve train will hit the pistons. something has to break, the valves, pistons, or the rods will bend.
The 2000 Mercury Villager uses a timing belt and has a non-interference engine. Which means that if the timing belt were to break that no engine damage would occur from the valves and pistons hitting each other.
The valves get bent by the pistons and the head/pistons an be damaged. In expreme cases the connecting rods can become bent or break and the crankshaft bearings can become damaged.
The timing belt is what keeps the valves from moving in synch with the pistons. If the timing belt snaps or cogs over the pistons are likely to collide with the valves smashing them both.
No it does not, it is a non-interferenceif the timing belt break the valves will not collide into the pistons.
One place to look for problems is the wiring where the harness passes from the drivers door into the body. After opening and closing the drivers door hundreds if not thousands of times the wires break where they have been bending all those years.
When Mercury and Iodine are ground together, a compound called Mercury(I) Iodide is formed with the chemical formula Hg2I2 but this compound is sensitive to light and will break down into elemental Mercury and Mercury(II) Iodide with the chemical formula HgI2 .Interestingly, Mercury(II) Iodide changes color with changes in temperature, changing from orange at room temperature to yellow above 126 degrees Celsius due to a change in crystal structure.
If it is a Mercury 1300 then remove the case and pop the internal BIOS battery - job done!
