I have a brake question

[Ilikeponys]

Ok so I changed out my front wheel bearings today and after I got done the brakes didnt work. They are drum brakes by the way. So I started it up and pumped the brakes a couples times and they worked. then when I let them off the pedal is really soft and they dont work, so I pump the brakes and they work agian. Does this mean I have air in the lines? What should I do?
thanks

Bleed them.

It could be a combo of air in the lines and adjustment. Firstly you should check your adjustment. All 4 drums should have just a small amount of drag when you turn them. Often times the adjusters freeze up and may need to be replaced. Then bleed all 4 wheel cylinders starting with the Passenger rear then passenger front , Drivers rear and drivers front last. It might take a few times on each wheel to get the air out. Hope this helps.
