The master that is in my car is marked F and R the f is toward the front of the car. The rear brakes being adjusted in too far will also give the result you are geting . Run the adjuster out untill the shoes just touch the drums as you put them back on and then adjust in about 4 or 5 clicks. Also check to be sure the front pads are in the corect place in the bracket, sometimes the pads will fall down out of their slots. Hope this helps i have fought the brakes on my car alot this year, found a bent rear bracket and spendel and think i have them good now.
