1998 chevy malibu tail lights trouble

When the brake is being held down and I turn on my right turn signal, the indicator inside the car flashes at almost double speed and so does the front right turn signal, but the rear signal doesn't blink at all.
When I'm not on the brake but the right turn signal is on, both the front and rear signal lights work fine.
I've replaced all the lights and the interface that the lights plug into and it still continues this strange behavior.
Any help would be great, thanks in advance

Where I would start looking for this problem is the ground circuit for the right rear light assembly.
Looking at the wiring diagram the ground is the only common thing between the two circuits.
What might be happening is that if the ground is poor or missing for that light assembly; the brake and turn signal maybe back feeding each other. That if only one, either brake or turn signal is used things look or somewhat looks normal.
Because whichever one is on it’s finding ground through the other’s bulb and its circuit. But when both are on and neither has this shared ground the lights will do some strange things trying to find a ground to complete the circuit.
If I haven’t lost you yet have a look at the wiring diagram; I’ve marked the ground circuit for the right side with red dots. That’s what I think may be the problem.
For testing purpose’s try running a jumper wire connected to a known good ground and the black wire as close to if not inside the right light assembly. If things start working normally then you know you’re close to finding the actual cause of the light problem. Keep moving your jumper wire down this black wire until the lights begin doing their thing; once there you’re found the location of the problem.
Remember I’m not there to actually see this so if I’m off base on this, post back and we’ll go at it again.
