So, as the title says, I replaced one rear control arm, and now my parking brakes are no longer working.

I chocked the wheels, engaged the parking brake and jacked up the vehicle, and both rear wheels can be spun.

I only touched one side of the vehicle, yet both wheels move freely.

Anyone have any ideas about what when wrong, and if so, how to fix it? I definitely need my parking brakes. My driveway is slanted to drain away rain, only now its just draining away my GTO!

When you put the replacement control arm in... Did it have a hub / parking brake assembly already? or did you take the original parts and swap it to the replacement control arm?

Sounds like it needs to be adjusted.

The control arm came with the hub assembly and brakes, but I switched out my original brake lines and rotor. I guess I need to adjust the shoes inside. I found a video online detailing how to do it.

I took my car in and had it realigned, and the mechanic peeled the boot off of my parking brake, revealed a set screw and tightened it down. I still need to adjust the shoes - the parking brake works, but my car rolls back about a foot before it fully stops.
