Answer
this is one of those things that you have to be there. but first thing make sure that the rear brakes are adjusted all the way if they are drum brakes,2 if you can do a psi test on the brakes it should be about 26,000 psi when the brake peddle is fully press, if not you could have a bad master cyl. combo valve could be bad.or still have air in the sys.also if you can try to bottle bleed.
