So in a few days im gonna be removing the end of one rear brake line to change the drum brake backing plate for only about 30 seconds and i figure i better bleed the system in case any air got in.

I know how to bleed the system with the pump and hold method with a friend where they push the pedal 3 times, keep it pushed down, open bleeder 1/4 turn for 2 seconds, tighten bleeder, release pedal and repeat until all air bubbles are out while making sure reservoir never goes dry.

My question is do i have to do anything different since the scion xb 2006 has ABS? Ive heard some cars with ABS have to use a scan tool to activate ABS actuators to remove air bubbles, but Ive also heard they are sealed and disconnecting a brake line for a moment wont let air into at least the ABS portion

Can i just do the traditional bleeding and be safe?

THANKS!

Yes, you can.

The rear drum already has residual valve built in to hold pressure on the springs so the drum dosen't totally collapse. Bleed traditionally and you'll be fine.
