Q & A, MGA, MGB, MGC, MG T-Type, Midget
Do you have any information on the brake booster troubleshooting? The problem is dragging calipers. Other sources have been checked out and the brake booster seems to be the culprit at this point. (kits were put in the calipers, rotors turned, new hoses installed, m/c has not been rebuilt but appears to be working correctly). The booster is functioning and providing assist to the brakes, but something appears to be interfereing with its action when at rest and pressure continues to be applied to the m/c.

the booster housing. We haven't found much information in the Haynes manual, or your tech manual, or the Porter book (1st edition) on the booster.
Any information you can provide would be useful.
