Recently my friend and I changed my rear brake calipers, we tried bleeding the RR but there was no fluid or any pressure. My front brakes is working are fine and the brake pedal feels normal to me.

Our guess my lines might be clogged, if there's any other ideas you have please let me know.

 

welcome to the board.

based on what you've described, i'm inclined to agree that there may be a blockage. maybe you should try disconnecting the line and try blowing some compressed air through it (obviously, you'll have to take measures to contain the fluid that will possibly be sprayed all over the place).

on a sidenote, out of curiosity, why were you replacing the caliper?

 

My back calipers that came with the car we're not good anymore.

 

well, i assumed that that's why you went through the trouble of replacement , but my question was more a matter of discerning if the possible blockage in the line was making it "seem" like the old caliper wasn't working, or was it failing in some other way.
