The rear brakes are often quite weak anyway. You might stick with the coaster brake if it operates correctly and upgrade the front brake.
Level 1: Replace pads with KoolStop Salmon.
Level 2: Replace front wheel steel rim with a CR-18 aluminium rim. That's a combination of work and /or money.
Level 3: Replace front brake with Tektro R559. It's a straight, bolt-on replacement. That, along with the aluminium rim, turns this into a bike with a vintage ride and modern braking.
If you are keeping the rear coaster brake, changing out the rear rim for aluminium doesn't get you anywhere except that it is lighter than the steel and it matches the front (if you did that already.)
