I asked this on my usual Civic forum to no avail. I have googled and searched HT to no avail. I own a 95 Civic Ex all stock except sounds and rims. One day I was driving and started hearing a horrible sound and horrible smell when braking. Found out that my brakes needed changing badly!!!!!!!!!!! I got the driver side done fine. turned out that only the driver side needed changing but had the pads and time so I did the passenger side. Got the new pads in and went for the test drive. A friend and I noticed the same horrible smell coming from the pass. side. got back home and jacked her back up. took off the wheel and had my friend press the brakes, no movement. I could spin the rotor by hand after a nights cool down. took off the caliper and had him press again. the piston came out but didnt go back in. I know it wasnt good to have him do that but I wanted to know what was wrong. Its out really far because my friend didnt hear me say stop. I removed the brake hose after removing the MC cap. drained the entire caliper of all brake fluid. still couldnt push it in by hand. took a wood block with a c-clamp and now the piston sits crooked in the bore. How to I remove the piston entirely to check the insides of the bore and outside of the piston. I have tried an air hose to get it out but nothing. I dont have money to buy a new caliper so I need help as I need this car drivable so I can get a job. Sorry for the long read but I NEED this fixed. Thanks in advance. Here's a pic of it:

 

Replace the caliper, you have probably ruined to square seal trying to get it back in. You may finally get it back in, but it will probably leak. There is a very slick rebuild lubricant that needs to be used to get the piston back in with minimal chance of damage.

You either had a bound up piston that you forced out with the brakes, a frozen caliper slide pin, or both. Since I can see the pins a stuck piston is most likely. A brake hose can do things of this nature if it has collapsed or is twisted excessively.

Check the rear brakes for abnormal wear. Any time you have brakes that wear more on one side than the other indicates a problem that needs to be fixed. If your brakes on the drivers rear are worn down more than the passenger rear, you have an internal hydraulic problem, bleed the brakes and check pedal feel, then replace the master cylinder.
