31 model a

I have a 31 coupe with a 40 rear and brakes. The rear bounces (hops) when I slow down. Any reasons for this?

 

Is the axle going up and down in relation to the body, or is the body going up and down? Both sides at once, or side-to-side action? Running shocks? What kind? What is the rear suspension setup? Pictures?

 

Are the rear brakes sticking or adjusted to tight compared to the front???

 

Severely warped drum, loose hub?

 

square wheels
