Default rear brakes

So i'm really annoyed and have no idea what went wrong brakes have never givin me a problem before. took my caliper off yeaster day took the old pads off threw the new ones on put it all back together and they wert even close to grabbing as hard as the old ones and the pedal goes all the way down. so i figured they needed to be bleed out so i did and no better. Since then i have taken it apart and put it back together atleast 10 times and just dont see what im missing. any ideas? thanks

If its put together correctly then the only other option is the rear master died.

Did you mess with any of the banjo bolts that connect the hoses? If so, that's probably the place to start looking. I always replace the crush rings, if I loosen and/or remove a hose. They are too cheap, and a air-leak too likely to not do it that way, IMO.

Try giving the bolts a little extra snugging, then re-bleed, that may fix the problem. If I'm reading your post right, from what you've done, I doubt it's the master, I think you aren't bleeding correctly because of an air leak.

Hope this helps, Ern

what hoses are you taking about the ones that go from the master cylinder to the caliber?

Yes, if you dis-connected any of the hoses from any of the calipers, master,the 't'-joint above the fender, etc., that's where I would focus your attention.

If you removed the pistons themselves, did you replace the seals there? If not, another possible failure spot.

My policy on brake components is to always replace any seals, crush-rings, etc. on any dis-sasembly/re-assembly. They are cheap and too vulnerable to damage during the dis-assembly process, to risk the potential failure/frustration.
