No, the piston has not fallen out of the caliper in your vehicle.
Yes, you need to remove the caliper first, then use the old brake pad and a C clamp to push down the piston of the caliper.
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.
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.
If the piston has come out, the caliper will need replaced.
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 fix a sticky brake caliper piston, first, remove the caliper from the brake assembly and inspect the piston for dirt and corrosion. Clean the piston with brake cleaner and use a soft brush to remove debris. If the piston is still sticking, consider using a caliper rebuild kit to replace seals or the piston itself. Finally, reassemble the caliper and ensure proper lubrication of moving parts before reinstalling.
you need to remove the caliper. then use one of the old pads along with a c clamp. put the old pad on the caliper piston then apply the c clamp till the caliper piston is completely closed. install new pads then reinstall the caliper. do the same for the other side. once you are finished crank up the vehicle and pump the brakes up until they are firm before you move the vehicle.
You can use a large C-Clamp to compress the caliper piston.
Remove caliper mounting bolts Slide caliper off rotor Use a "C" clamp to fully retract piston into caliper body If parking brake is used on this caliper piston is threaded and a special tool (not expensive) is required to thread piston into caliper body
Dual piston caliper, 85 ft lbs. Single piston caliper, 37 ft lbs.
The caliper piston may not be compressing properly due to air or moisture in the brake system, a faulty caliper seal, or a blocked brake line.
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
