[Spridgets] Brake problem

[Joe Lansing]

I am trying to identify what my brake problem is. I can't get my system to hold pressure. I've bled all 4 wheels. The system pumps up with the pedal (5-6 strokes) but won't maintain pressure - there is nothing if you try again in 10 seconds.

I just put rebuilt disk calipers on my car. I rebuilt them with new soft goods. They were old units that had been sitting for years. I also have an old master cylinder with scarring on the cylinders. In the past I could put a kit in and it would last for a couple years.

Where should I look? The new calipers? The master cylinder? Any special tricks to getting the air out of rebuilt calipers?

Thanks,

Joe
