Rear Tires Suddenly Lock Up Going 65

Have you ever replaced the brake hose that bolts to the axle, where the rear metal brake lines attach? Maybe it's closing up and locking the rear brakes.....Like the front brake hose would lock up one wheel it's locking both because it's the only way in or out for the fluid to go.....

I'm a little confused on what you mean..

I may have applied brake pressure after the "lack of power" feeling but I'm unsure. This may have really locked up the brakes and after the tires locked up I for sure applied the brakes and controlled the car to a stop. I don't have power brakes, or power steering so it was a rather terrifying experience.

I've never replaced any brake hoses. I'm a new owner to this duster, I bought it about 6 months ago. Had a cam go flat and I rebuilt the carb, added msd ignition and wires, interior work, etc etc. I've put maybe 1000 miles on it..if that.

Other people have agreed that it may be a brake problem so I wan't to cover everything and find the problem before I take it on a drive.

Will update and add pictures as I tear into it.
