Rear disk brake question
 

I just installed new pads and rotors in the rear of my civic. I noticed today that there is some surface rust on the rear left rotor where the pad should be making contact when braking. The caliper is original 1990 whereas the other three are rebuilt. Does this automatically point to a partially seized caliper? Or could it be something else? Is it easy to rebuild these if necesssary, or would I be saving headaches if I purchased a reman. one.
Thanks for the help.

i would just buy a remanufactured one to save yourself the headache. they can be really difficult to take apart when they get good and rusty.

I'm going to have a look at the guide pins again. I overhauled them but I guess it's possible water could have got in. Perhaps the dust boots are torn. Seized pins could also contribute to my problem, right?

when u replaced the pads and had to turn the piston back in, did it go back in smoothly?

I actually managed to squeeze the pads into position without turning the piston. I only tried to turn it with some pliers but wouldn't budge. I figured I didn't have the right tool and didn't worry too much. Guess it could be seized afterall?

what the ****? it went on with new pads and rotors? That's unpossible lol.

Use a pry bar.. put it in the centre of the cross and push in and turn with the bar.

Rebuilding a caliper is easy as pie with compressed air or if you like getting messy with a grease gun, but the price of a reman caliper is peanuts. I'd just get a new caliper.

I guess maybe because it was partially seized it allowed more room? Then again I did take a mallet to it lol.

Thanks for the replies. I went ahead and ordered a new caliper and will have everything checked by my buddy, who's a mechanic, just to be safe.
