Default Rear Pistons coming out!!!

2001 Integra
I took off the rear pads because they were rubbing and I was attempting a quick fix so I can get rolling around before completely replacing the rear rotors, pads, and calipers, and figured out the hard way the repercussions of doing so :






Tried pushing pistons back in to no avail, tried bleeding the line a bit to help push them in, could not do so all the way. The pistons are causing brake fluid to leak, so I'm wondering

1. Is there quick fix to get these calipers back on/not leaking so I can drive around?
2. Is there a way to plug the line quickly, so I can just take off the rear calipers and roll around only using the front while not having to worry about the back leaking

They screw back in... not press...... righty tighty. Make sure your e-brake is disengaged to get them to fully compress. Those pads must have been goooone, or you pumped the pedal without pads in it.

I can't tell from the pictures but did the piston come all the way out of the seal? If so you need compressed air to get them back in.

Oooooooooooooh they screw back in...
the pads are pretty rusted with the rotor, not sure what they started rubbing (it was after my rear coilover/lca install)
Thankfully the piston didn't come all the way out of the seal, I actually pulled it a bit at first trying to readjust it to go back in.

Should I Just rescrew them in and roll with the shitty rear pads, or is their way to block the brake fluid line? I lost a good bit of fluid, but as long as my brakes still work for the most part I'll just take it slow and easy until I can get a overall in check.

Obviously you'll have to refill and bleed the system. You can get tool at the parts store to help you turn the piston with a ratchet.

Just rescrew them in and run whatever you have. There is no good way to block the rear brakes without causing a lot more work later down the road. Unless of course you can machine a brake line cap or plug. In any event, it would be ill advise especially on a wet surface. Be prepared to pump them brakes LOL!

Yeah thanks for the help, I went out and brainstormed using a wrench, then I remembered I bought a pair of vise grips and those did the trick easily.

Took the car out for a spin, definitely not a firm brake feel bit it'll do for now

No. You're playing with safety items here. It's not a lmao situation, it's wanton negligence. Fix it.

It's also my best judgement, and how I use it. When I can bleed it I will.
The car still has plenty of stopping power and I'm not doing freeway driving/don't get anywhere near tailgating.
Thanks for the help though

You do realize the integras brake system is cross linked right? As in, right rear caliper takes a **** and pukes, tge left front brake also takes a ****. Our cars arent front rear split, theyre diagonally split.

Jesus christ. Just put the brake pad that's completely worn out back in. That would be 10x safer than nothing. Brake pads are like 20.00 for cheapies... If you are replacing rotors anyway what does it matter if the steel brake pad backing is grinding?

I did replace the rear pads lol... why would I want the pistons coming out again haha
Yeah I am planning to upgrade the entire assembly (undecided on steel line though) and already have the big brake fronts prepared...not I just need to see what would be good for the back. But they do the least amount of braking anyways so ¯\_(ツ)_/¯
