I believe you need a speaical tool that most parts stores sell, it fits into the piston and you can turn it with a ratchet and extension as the calipers acually turn to go in and out like a screw.
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.
How do you get the brake piston to retreat back in caliper ?
replace brake hose they colaspe
# 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
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
Use a "c" clamp to fully compress piston into caliper body
There is a 14 mm bolt on back of caliper. Remove this & use a 4 mm Allen wrench to back piston into caliper.
Use a large C- clamp to depress the piston enough to remove the caliper.
The brake caliper piston seals are bad.
Hydraulic force, transmitted by the brake fluid.
You can use a large C-Clamp to compress the caliper piston.
The piston is forced out of the caliper by the pressure of the brake fluid. This pushes the brake pads against the rotor, in turn stopping the vehicle.
