You need to turn the piston clockwise and it will slowly retract as you turn.
To retract the brake caliper piston on a G20 Infiniti, you'll need a brake caliper tool or a C-clamp. First, remove the caliper from the rotor by unbolting it, then position the tool or C-clamp over the caliper piston and gently turn or squeeze to push the piston back into the caliper housing. Ensure you do this slowly to avoid damaging the piston or seals. Finally, reassemble the caliper and check brake fluid levels before testing the brakes.
if it is the caliper at the rear u need the special tool to turn the piston clockwise to push in and counterclockwise to pull out
To change the rear brakes on a 2000 Infiniti G20, first, lift the vehicle and remove the rear wheels. Next, remove the caliper bolts and slide the caliper off the rotor; support it to avoid straining the brake line. Replace the old brake pads with new ones, ensuring they are properly seated, and compress the caliper piston if necessary. Finally, reassemble by reinstalling the caliper and wheel, then lower the vehicle and pump the brake pedal to ensure proper function.
How to replace starter on a 95 G20 infiniti?
Yes. The rear bumper cover was the same on the Infiniti G20 from 1999-2002.
You need a caliper tool and a ratchet. Caliper tool is a cube with prongs on it, a couple dollars at a parts store or online. Just turn the caliper tool and on the caliper and it will compress.
Easiest way is to use an old brake pad and a C-clamp. Put the pad over the piston and crank the clamp. If you don't have an old pad, use a small piece of wood to cover the piston.
To change the front brakes on a 1999 Infiniti G20, first, lift the vehicle and remove the front wheels. Next, remove the caliper bolts to take off the caliper, then detach the old brake pads from the caliper bracket. Install the new pads, reattach the caliper, and ensure everything is properly tightened before putting the wheels back on and lowering the vehicle. Finally, pump the brake pedal a few times to seat the new pads before driving.
I posted this question and finally was able to get them to retract with pure determination and elbow grease. The caliper piston is tight and takes many clockwise turns. Lube and loosen the seal around it with a very small screwdriver, so it doesn't tear when you turn the piston. You need a special spanner wrench to turn them. I was able to make one, by putting (2) 1/8" pins into the end of a 1 1/4" x 1/4" piece of bar stock, that was 10" long. I started to use a pair of vise grips(and you could get away with them) but they bugger up the end of the piston. If you use grips, file the end of the piston flat afterwards. Good luck, Eric J
