HI there! I would replace the caliper that the piston popped out of, then on the other side,try turning the piston back in. It shouldn't work like the front, but actually screw back in.
So I need to replace the entire caliper on the passenger side?
I would,these aren't an easy rebuild like the fronts. You can try and get a seal kit and screw the piston back on. Here is a picture of the tool used to push the picton back in.
Sorry,HERE is a link. You can get this at most parts stores.
You just use a 3/8 extension and ratchet
What about the jammed piston (the one that DIDN't fall out)? I can't screw it in...it just won't budge.
If it won't move at all then it needs to be replaced. It is either out to far or there is rust on the piston and it is tight to the caliper housing.
The piston needs to be replaced or the whole caliper?
Normally it would be the whole caliper. I suspect you will have no luck finding a good rebuild kit
I am sure you could online,but us re builders are kind of a thing of the past :)
So it sounds like I screwed everything up enough so that I simply have to buy two new calipers?
Well, I suspect it will be the easist way to repair it all.
and if the piston wouldn't screw back in on the one, that is nothing that you did
it is the nature of the rear setup
Man, I thought I'd save some $ by replacing my own pads...
Thanks for your help. I just hope I can find calipers from a store today! I need to get the car back on the road. TAke care.
I understand man! good luck with it and you are very welcome!
