87 D150 intermittent brake problem

From : ewb4arch

Q: just recently bought this beater truck. with all the various parts ive bought im approaching what i paid for the truck! in any case heres my problem. replaced one of the rear brake hard lines due to a leak. bled the rear lines. all seemed ok for a couple short trips. then pedal suddenly went almost to the floor with little stopping power. thought i had another leak or air in the system. bled the rear again attempted to bleed the front...bleeder valves rusted shut so i replaced the calipers good thing too since the pads were pretty bad. bled all four wheels and test drove truck. brakes worked great! next couple trips all well. latest trip the brake pedal would work great with little travel same as the previous trips after new the calipers but occasionally would travel nearly to the floor with poor stopping power. it seemed to do this more often if i would lightly apply the brakes then let up on the pedel then reapply. does this sound like there is still air in the system or an intermittently failing master cylinder being an intermittent problem has me wondering since it doesnt seem like a normal problem. thoughts thanks eric its the master cylinder. i hit a ford explorer with my 68 fury last year same deal. really teed me off it did. no harm to the explorer and a caved front bumper on the fury. no big deal off with the old on with the undamaged one. .

since the op notes that its starting to slip on the 1-2 shift as well i meant to say rear clutch pack. the front clutch pack would have nothing to do with the 1-2 shift slipping. did it occur to you that there could be multiple problems a loose front band in conjunction with a faulty front clutch would explain the symptoms as would a clogged filter. a slipping rear clutch would affect 1st gear also. further if the front pack were slipping hed have said something about reverse slipping not clunking. a front clutch that slips at normal forward line pressure will often engage in reverse because the line pressure increases by a factor of three or more in reverse. of course you already knew that this could also explain the clunk a leaking clutch would tend to apply suddenly rather than smoothly. i would recommend the op remove the pan check the filter and adjust both bands. try adjusting the front band. if that doesnt do it and im guessing it wont your rear clutch pack is worn. . of course you meant to say front clutch pack. ive been having some issues with the automatic transmission on my 96 dodge van recently. it has a v8 motor with a 3 speed automatic transmission and ac. the transmission seems to slip when going into the top gear the slip seems to start around 28-30 mph and it doesnt fully engage until around 38-40 mph lifting my foot from the gas seems to help the shift. it has also started to slip a little when going from 1st to second gear and will occasionally clunk into reverse when i shift. ive checked the tranny fluid and it seems to be at or near the correct level. can anyone suggest what the problem might be best regards. bed .
