Brake Repair

I made to to my daughter's house Saturday somehow. The voltage regulator on the rebuilt alternator gave out but it was still keeping the batteries charged. I still need to take that off and have it fixed again. I don't know how I made it in without the air brakes locking up on me though. On Monday I bought a repair kit for the air brake air dryer system for $170. The fixed one problem but not all of it. With the engine running, the air drier purged the air a couple of times but it didn't seal after purging and was leaking air. I did find an air leak in a cracked air line and fixed that. Then I ran the engine at full RPM, the dryer purged then remained opened. I ordered a rebuilt air dryer today for another $335. It should be in tomorrow.
