Where are you seeing bubbles? In the tube that you’re bleeding out of or are you seeing bubbles in the glass “window” of the master cylinder? If it’s in the glass window, that shouldn’t be a problem.
Sometimes, as you break open the bleeder “nipple”, air appears to escape, but oftentimes it’s air getting through the threads. If that’s the case, you should be okay, but you want to keep an eye on it. Just pay attention to the pedal action as the brakes heat up. If the brake pedal ever feels spongy, you still have air in the system.
