Hi, this was my first time changing a caliper. I followed this video:

After waiting for the air to drip out of the bleeder valve for 20 minutes, I followed up with getting 2nd person to do a few pumps until I saw no more air coming out of the bleeder valve. I made sure to refill the brake fluid reservoir so it never even got down to half full.

After test driving a half mile, on the way back the pedal got soft. Pumping the pedal doesn't help it.

What should I do? Does this mean there is still some air inside the caliper that I need to bleed out?

 

Yep, still ait in the line. Try bleeding all 4 brake lines, in the correct order. BTW, air will not "drip" out of the brake line.

 

 

Thank you guys.
Today I tried just bleeding that same rear right brake, but no luck, pedal still soft when I turn on engine. So I will do that one over again, as well as the other 3 wheels.

Is it OK to do 2 wheels one day (rear right + left front), and the other two wheels the next day? I won't start the car, just physically difficult to do all 4 in one day.
And how many times should I open and close the bleeder valve? Would 10 reps be good enough?
