Brake caliper piston

[Merritt5]

I have a 93 Fox that I have upgraded the brakes to a 94 mustang system (mc, calipers front and rear).

On the driver rear, when you press the brake (you have to pump, but we'll get to that) it clamps the rotor like normal. As you release the pedal, the piston retracts 100%.

I know the piston is supposed to retract some to free up the rotor, but go all the way back in? I will also add this is a new caliper from the parts store (2nd one to be exact, 1st one had the same issue.)

Anyone else had this issue and is it normal?

I'll post an update.

The day I started the thread, I gravity bled the brakes and was having the piston issue.

Next day I got out and the piston seems to be working fine.

If anyone else is having this issue, check out the link. It gives you a few things to try with integrated parking brakes
