Disc/drum rears locking up?

[JRouche]

Did you re-build the rear cylinders? If not I would think about tearing them down and make sure they are not hanging up. You have some great brakes in the front. Might be worth a re-build for the rear cylinders including the entire shoe mechanics.

Im not all that knowledgeable about brakes. But what if the fronts just werent getting enough pressure. Lots of volume. But they need more pressure and less volume than the drums. So then the drums are getting all the volume they need and are actually working as they should, drum brakes really have some gripping power, they just tend to fade under high heat. Where the fronts arent getting the pressure they need and are not doing their part. Just an idea. JR
