Use a C clamp to push the piston out of the way to remove and also to place back on rotor.
You can use a large C-Clamp to compress the caliper piston.
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.
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
You will need a caliper rewinding tool
C or G clamps.
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
It requires a special tool to turn and compress the piston in at the same time.
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.
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.
Use a "c" clamp to fully compress piston into caliper body
Get a 4 Inch C Clamp Leave the Pad In The Caliper On The Plunger Side Open The Clamp Wide enough To Clamp on The Back Of Caliper and Pad. It should Easily compress. However, as these are rear disc, the emergency brake is connected as well. A C clamp will not work in this situation because the piston caliper is threaded and has to be retracted by turning the piston caliper with a special tool that can be gotten at most auto parts for around 10-15 dollars. Make sure the cap is off the master cylinder reservoir. Not difficult.
