I'm trying to keep my winter beater on the road.

There was a split in the rear brake line which I had fixed at a local shop. It no longer leaks brake fluid, but the pedal now has to be pushed practically to the floor.

Before I take it back to the shop, I'd like some ideas of where the problem could be. How do power braked work? It feels like there is no booster working. If I pump the brakes they form up. Could the low fluid have broken the brake booster?

Is it just air in the lines?

Thanks for your insights.
