Have you rebuilt calipers before?

I'm rebuilding some 83' 320i ATE's (for a single line 1600) and the instructions say it will be very easy to push the piston in... I'm thinking mine is WAY too easy, if I turn it upside down, the piston will actually drop right back out! I've rebuilt other makes and models, and they all had more resistance than this. Will this really seal if I put them on the car? I've double checked, and this is the ATE kit, for these ATE brakes. but with that little of resistance, I feel like there's something wrong and doubt their sealing capabilities. Or do the ate inner seals swell a hair after soaking a while?

I'll agree with you, every piston i've had has been a relatively tight fit. I've had to use compressed air with a block of wood in the caliper to get most of them out. They sell a product, I think it goes by the name of Brake Caliper Make Up Oil, it's like lubriplate for rebuilding calipers. I'd say try some of that or brake fluid and see if the seal tightens.

Sounds like you have the wrong seals-

it should be a pretty healthy push to

get the piston back in. I often have to

use a block of wood to get better leverage.

But they should push in with hand pressure.
