Location: Milwaukee Wisconsin | 1954 mopar dodge royal . Say .. what would cause my pass front brakes shoes to hang up ? I did a brake job on it allready replacing all 4 corners with new cylinders , shoes and cleaned up everything in there ........clean as a whistle... nothing is wet or leaking in the drum , wheel bearings were cleaned and repacked. bearings are fine and rolls fine .. just when you try to go forward it hangs up and drags that pass front wheel .. but does not hang up in reverse motion . My guess is a front pass rubber brake hose collasped. . what do you guys think ? Thanks . john |

Location: Milwaukee Wisconsin | somone else replied and said that if it were the hose collasped ... it wouldn't move in either direction..... don't know the answer to that .
here is the thing though .. when it is locked up going forward ( tight ).. you can raise that wheel off the ground ....... and it spins freely. |

Location: Perth Australia | Loose wheel bearing or, perhaps, the brake lining does not quite match the contour of the drum, so the leading edge is grabbing and forcing the brake lining out towards the drum?
But make sure the brake hose isnt kinked when the car is sat on the ground?
The wheel bearing is my bet though

Location: Netherlands | This is a 'fairly' common issue and has been discussed earlier on this forum.
My '62 Wagon had the same issue years ago.
I solved the issue and improved the system at the same time by using brake pads instead of brake shoes

I was thinking that was the culprit. |

Location: South Central PA | I had the same problem with my windsor too. When I acquired the car it had just had a brake job done and the right side would lock up. I replaced the hoses, bearings and flushed it and it still locked up. Turned out being the master cylinder, it had so much rust and gunk in the bottom of it that I couldn't see until I pulled it out and dumped it. Eventually I converted it to disc/dual mc so I wouldn't have the hassle anymore. |

Not necessarily, a slight drag would tend to make the shoes grab in the forward direction of rotation but not the rear. |

Location: Milwaukee Wisconsin | guys ......
here is what I observed today on the brakes.
looked at the inner bearing and that looked fine spun good nothing chewed up. full of grease.
switched the drums from sided to side and it still locked up.. so it is not the drums or bearings.
adjusted the heel toe adjustments top and bottom again on the pass side shoes. still no diff ........still locking up.
Then I opened up both bleeders on the cylinders .. it had pressure on both and squirted out fluid until the pressure subsided. then I got in the car started and tried to move the car forward and it moved freely with NO locking up .. so It appears it is the brake hose. I have two new ones coming wednesday.. hope that does it. |

Location: Perth Australia | Are you sure its not that residual pressure?
That could be from the M/C
I have been playing with the adjustment rod between the pedal and the M/C on mine, as if I set is so I have a little free play on the pedal, after a while, first brake application goes to the floor, then its ok
If I adjust the freeplay out, it always has a good pedal, but, when it sits for a while, the brake light will come on and the brakes drag
Just curious though
You said you had pressure on both sides?
is that without touching the brake again?
If you release the pressure from 1 bleeder, that should have dropped all line pressure (if you let it bleed till it stopped)

If you release the pressure from 1 bleeder, that should have dropped all line pressure (if you let it bleed till it stopped) on my brakes there is one upper cyl and one lower cyl.. I loosened the top cyl first and it had pressure on it. the lower one would have been just gravity draining it out then . but once I took the pressure off the 2 cylinders, it rolled forward without locking up. obviously I did not touch the brake after I drained the fluid out of the cyls. and that is a good sign that it is not a bearing then. or something not running true . it's has to be that brake hose is my guess. john |

Location: Perth Australia | Now I get your meaning
I would re bleed up the side you did, get the fault to happen again and see what happens if you undo the bleeder on the other side
If it also has pressure, then it probably isnt the hose
If the r/h one is jamming up and the left isnt and there is pressure in the whole system, then (as said earlier) your return springs could be the trouble as, if the right springs are weak, it will take less pressure to move the shoes out to the drum

Location: Pittsburgh, PA | Some brake shoes have oil or fluid in them, even after cleaning. They 'lock' on the first application, but work fine for a while until the car sits again.
Old mechanic's trick. Soak them in brake cleaner for a few hours, then set them on fire to burn out any fluids embedded in the shoes.
The temperature of the fire is lower than standard opertating temperature, so they will be fine. I did this on my '59 DeS and haven't had a problem since. Odd, yes -- but it works. |
