So I was working on changing my rear brake pads and not having a good time. Trying to wind the caliper back when I noticed brake fluid starting to leak out . Turns out I had accidently gotten a small tear in the boot of the piston. My question is how screwed am i? I taped over the hole with gorilla tape just to plug it for the night but is it possible to rebuild that or do I just have to buy a whole new caliper?

I'm guessing a new one is in your future. Honestly, I'd get a used one.

Should find a rebuild kit for cheap. Just a few o-rings

Some possible kits. Make sure you gets kits for rear calipers.

Thanks for the tips everyone, and thanks for the link. Looks like even repairing it ain't gonna be that cheap :/ I swear I should've known better than to try and work on it these days but I just can't get over trusting anyone else with my car.

If I were to put them back together with silicone sealant over the tiny hole would that be incredibly stupid just to get it to my mechanic?

nevermind was looking at the wrong section lol that's stupid cheap.

The boot isn't the source of the leak, it's the piston seal. Hopefully and most likely it's simply damaged. But it can also be a problem with damage to the caliper bore.

indeed.

that rubber boot isn't holding the brake line pressure...

Well there's a tear in the boot that I can see brake fluid oozing from that if I put my finger over the leaking stops. It happened after I accidently dropped the caliper on the rotor right on the boot. I"m not saying you are wrong I'm just describing what I see.

Is the boot not sealing in any brake fluid? I mean I've gone as far as replacing wheel bearings on other vehicles before but never rebuilt a caliper before. So are you saying that the seal is leaking fluid into the boot and just so happens there is a hole there for it to come out of as well

Either the piston or o-ring is damaged or the piston came out of the bore allowing brake fluid to leak out. The rubber cover is there to keep contaminants out.

Got you, makes sense now. Thank you.

Yeah pretty sure the piston came out, had the tool to push it back but it wouldn't move (because of having to twist it) but then couldn't get to the tool out without hammering the screw counter clockwise (granted I have muscle weakness due to a condition). Anyway took the tool out and started to twist it and it was going for a bit but then wouldn't budge and all the sudden started to expose more and more of the piston as if it was applying the brakes. I figured it was just going to the position it was in with the old pads.

I've never had issues with changing pads like this before but then again I wasn't trying to do a brake job with severe memory loss either, I haven't checked on it today I'm guessing I'm gonna go out there and the piston is gonna be on the ground somewhere and all my brake fluid is going to be all over the place. Ugh I should've just taken it to my Saab guy.
