Rewind it with a piston rewind tool or, at a pinch, use needle nose pliers.
You can use a large C-Clamp to compress the caliper piston.
To compress the caliper piston on a 2007 VW Rabbit, you’ll need a brake caliper tool or a C-clamp. First, remove the caliper from the bracket, ensuring you support it to avoid straining the brake line. Then, place the tool or C-clamp over the piston and the back of the caliper, and gently compress the piston back into the caliper housing. Make sure to check the brake fluid reservoir, as compressing the piston can cause fluid to overflow.
To compress a caliper piston, you can use a brake caliper tool or a C-clamp. First, ensure the brake fluid reservoir cap is loosened to avoid pressure buildup. Then, position the tool or clamp against the piston and the back of the caliper, and slowly apply pressure until the piston is fully retracted. Be cautious not to damage the piston or the caliper during the process.
To compress the rear brake calipers on a 2008 Taurus X, you will need a brake caliper tool or a C-clamp. First, remove the wheel and brake caliper to access the piston. Then, either use the caliper tool to rotate the piston back into the caliper housing or place the C-clamp over the caliper and gently compress the piston straight back. Ensure the brake fluid reservoir is checked to avoid overflow during this process.
To compress the rear brake caliper piston on a 2003 Acura MDX, you need to first ensure the brake fluid reservoir is capped to prevent overflow. Use a caliper tool or a C-clamp to gently push the piston back into the caliper housing. Make sure to apply even pressure and check that the brake pads are properly aligned as you compress the piston. Once fully compressed, you can reassemble the caliper and install it back onto the vehicle.
on a mazda3 rear caliper there are two dimples in the piston, you can use needle nose pliers to turn the piston while you push on it, or you can rent a caliper compression tool from a local auto parts store, if there is a harbor freight in your area you can buy the tool for around $20. using a c clamp will damage the caliper, it has to have pressure and rotation to be compressed
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
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
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
You will need a caliper rewinding tool
C or G clamps.
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.
