so i had a very spongy pedal, which i fixed with a booster off a parts car, my car is rhd, i used a lhd booster (shouldnt cause a problem right?). and i also had to replace my BMC (my new one came off the same car that the booster came from). first time out with my car all 4 wheels locked up, car wouldnt move all 4 brakes were smoking horribly. i adjusted my brake pedal and everything seemed fine. drove the car about 60miles and they began to lock up again! so i released the pressure at the master cyl. and i adjusted my pedal again. i was able to make it 4miles back to my house. ive read some threads on this topic but i havnt found a clear answer. i dont think i should have to adjust the rod in the booster since it came off the same car the master came from. i know for a fact it is all bled correctly. any ideas of what could be causing this? thanks!

When adjusting the booster push rod,you should only do 1/4.. also remember to leave some play in the pedal.
