bleeding rear brakes - only 1?

I was bleeding my brakes today, as I replaced the brake master cylinder. A lot of air, I didn't bench bleed. <br><br>When bleeding the brakes, I did not find a bleeder valve on the passenger side of rotors / rear. Is this correct? Only one on the driver's side? Can someone help me? thanks. I have the repair manual but it doesn't say anything.<br><br>Thanks.
