I just did rotors and pads all corners of the car. I got finished and I tried backing out and one of the rear calipers locked up. What's wrong? Yes my e-brake was down...

My friend told me a spring in the caliper must be stuck therefore I need a new caliper. Would it be semi safe to drive a couple days without one rear caliper?

 

is this a serious question or just trolling?

no, it's not safe to drive with 3 working calipers... disassemble it and figure out what you did wrong, which i assume is not compressing the caliper properly by TURNING the piston in and not just trying to collapse it.

 

I used the proper tool to twist the piston in. I did the same to the other side as well. But the driver rear is just locked up

 

then disassemble it and find out what is hanging the wheel up. if the caliper compressed properly then it is unlikely that it is frozen. perhaps the e-brake mechanism is locked up or adjusted(it should not have been).

 

i did disassemble it. i found nothing wrong with it. what do you mean by frozen? like literally by temperature? would i just replace the whole caliper?

if the wheel is locked up and you disassembled it and found nothing wrong with it then you aren't looking hard enough.

physically inspecting everything and putting the wheel back on does no good if the wheel will not turn. if you reset the piston and each time you hit the pedal the wheel is locking up then you need to specify that.

list everything you've done, we're not psychics.

 

It turned out to be the caliper bracket bolts were too long. They were jamming into the rotor ruining the rotor. I just got the rotor machined smooth and used washers. I think whoever did the brakes before me used wrong bolts because they were on there very loose when I was taking them off.

 

Ah, the joys of discovery...

Glad it worked out.

I would suggest ordering the right bolts. You have no idea the quality of the ones someone else chose that fit. Also, a picture or a comparison between your car and another might be warranted in the event that the bolts are right and everything else is hosed.
