You can use a large C-Clamp to compress the caliper piston.
with a c clamp. put a block of wood or your old pad over the piston and tighten with clamp.
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
C or G clamps.
You will need a caliper rewinding tool
The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper. The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper.
The piston on the rear calipers will not compress as most vehicles do, they must be screwed back to there fully recessed position.
AnswerThere is not enough information in your question. A cylinder piston you do not compress, you compress the rings in the piston. There are pistons in the brake system. There is no way of knowing the problem without being more specific.I'm assuming you mean the caliper piston. If it can't be compressed, replace the caliper.
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
It requires a special tool to turn and compress the piston in at the same time.
Use a "c" clamp to fully compress piston into caliper body
there is a special tool that can be purchased at any auto parts store made specifically for compressing brake caliper pistons. I personally use a 4 inch c-clamp. works every time.
# Preparation For Brake Pad Replacement # Remove the Wheel # Unbolt the Caliper # Remove the Old Brake Pads # Compress the Brake Piston # Re-Install the Brake Caliper
Shade tree mechanics use a C-clamp and a flat steel bar to compress the piston. I have also used a large adjustable Channel-Lok-type pliers to compress.
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 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.
Use a C clamp to push the piston out of the way to remove and also to place back on rotor.
Loosen something on the brake if you tighten it will get worse screw caliper piston in or out with caliper tool. they are like that for the park brake function
You can use a C-clamp to compress the caliper on just about any vehicle. You might want to place some rags near the Brake Master cylinder because brake fluid will travel back into it from what is left over in the brake lines. If you don't, you will spill brake fluid onto the floor.
If you can't compress the piston with a C clamp back in to position to fit the new brake pads I would suggest replacing the caliper completely.
some model's that have the parking brake Incorporated into the rear caliper, you must compress and turn the piston until the proper clearance is obtained.
A Caliper Reset Tool is a tool used to 'reset' the brake caliper piston on calipers with an integral handbrake system. The tool spins the piston while applying pressure to compress it enough to replace the old pads with newer thicker ones.
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.
You need a tool mostly used on ford cars that turns the piston while pressing it.
When you are changing disc brake pads, you should use one of the old pads and a large clamp to compress the piston immediately after removing the caliper. This helps to prevent air from entering the brake lines.Use caution when positioning the clamp so that it does not put any pressure on the brake hose, bleeder valve, or anything other than the piston housing.If the piston is difficult to compress, you may have a frozen caliper and/or a leaky brake hose.
