you need a special caliper tool that turns the piston as it pushes it in, or if you are on a tight budget grab a wrench and a regular caliper compressor and turn the caliper clockwise as you tighten the tool (or ask someone for help, easier with 2 people) hope this helps.
How do you get the brake piston to retreat back in caliper ?
if it's like older jetta's or most imports you need a special tool{or a channel lock pliers} to turn the piston back in
You need a tool that can compress the piston at the same time you can rotate the caliper clockwise. Or you can use a clamp and a screwdriver to gently compress the piston.
If the emergency brake is not connected to the caliper use a "c" Clamp If the emergency brake is connected to that caliper a special tool (not expensive available at Sears or auto parts) is needed Caliper is threaded. Turn Clockwise to compress

You can use a large C-Clamp to compress the caliper piston.
Replace the caliper and bleed the brake system.
To change the rear brakes on a 2004 VW Jetta, start by safely lifting the rear of the car and removing the wheels. Next, remove the brake caliper by unbolting it and sliding it off the rotor, then replace the brake pads by sliding them out of their slots. Use a brake caliper tool to compress the caliper piston back into its housing before reattaching the caliper. Finally, reassemble everything, ensuring all bolts are tightened, and pump the brake pedal to ensure proper brake engagement before driving.
I have used a large "C" clamp, to compress the caliper flush to the face.
To change the brakes on a VW Jetta, first, lift the car and remove the wheel. Next, remove the caliper by unscrewing the caliper bolts, then slide the caliper off and support it with a bungee or rope to avoid straining the brake line. Replace the old brake pads with new ones, ensuring they are properly seated, and compress the caliper piston if necessary. Finally, reattach the caliper, replace the wheel, and repeat the process on the other side before lowering the car and testing the brakes.
Yes; the Volkswagen Jetta tdi had a thick disk brake in the front end and the rear disk brake is larger in diameter than the front brakes but not as reinforced.
