You can use a c clap and a piece of wood, put the wood in between the clamp and the round contact area of the caliper and slowly clap it, make sure the brake gluid cap is off, this will allow the fluid to be forced back up out the system, when u go for a test drive, screw back opn the cap, and pump the brake several toimes vefore you move, here youll be building up the pressure again for a minnute youll feel like your brake pedal has no resistance, not to worry, the pressure will builf up every hit you give to the brake pedal.
It requires a special tool to twist the piston back into the caliper.
How do you compress the rear break caliper, pistons on a 2002 Sierra ?
Yes, a special tool is required to compress the caliper pistion.
Chances are when a brake caliper wont compress it is the type that must be turned and compressed at the same time and requires a special tool that you can borrow from a local chain auto parts like Auto Zone. That was the case on my 96 Buick Riveria rear disk brakes. Hope this helps.
I have used a large "C" clamp, to compress the caliper flush to the face.
Remove wheel, remove caliper from mount, not from the brake line or the cable, get proper tool for working on rear disk brakes then twist the piston and compress it back into the caliper, install in reverse order.
If I recall, a g6 has disc brakes front and rear, and are largely identical to the disc brake systems on most other cars, except for one thing; the rear g6 calipers cannot be compressed manually to fit in the new pads. A special tool is required to compress them. If you don't have that tool, you can't compress the caliper piston. If you can't compress that caliper piston, you can't fit in the new pads. Ask at an auto-parts store for a "Disk Brake Caliper Tool" set. Should be less than 30.00usd depending on the brand they carry. Note: The g6 *front* brake caliper pistons compress manually, no special tools needed.
Our 2003 Impala has brake pads.

Chevy came up with the brilliant idea of turn in calipers a number of years back. Check the inside of the caliper piston cup. If you see a square depression in the center, it is a turn or twist in caliper. DO NOT try to compress it. You'll damage the caliper and increase your brake job costs.

It has rear disc brakes with the parking brake built into the caliper.
I have a 2004 TSX and learned the hard way how to change the rear brakes and had to buy a rebuilt caliper for my mistake. Most brake calipers compress with a simple C-clamp to make room for the larger/newer brake pads. The rear brakes on a TSX are different and you'll notice they have a couple of grooves on the caliper piston. They make a tool that is sold at AutoZone that allows you to compress the caliper piston by rotating it clockwise back into the piston. (It looks like a metal cube with metal prongs sticking out) I also recommend using brake grease on the exposed caliper piston boot prior to compressing it as this will allow the piston to rotate without damaging the boot. Don't forget to bleed the brakes afterward since rotating the piston will likely allow some air into the brake caliper.
