Hey guys, I'm going to finally spray my engine bay and I'm ready to run new brake lines. I dug out the old junk from the pile and found that this system (I did not strip car) has 2 "switches" in it. Neither of these blocks have wiring so as far as I can tell there is no brake warning for the dash. I'm running all new lines from the MC, and need to decide what to use. Below are pics of the units, the one with no markings was first in line from mc to wheels. I will be installing a proportioning valve on the rear line but do I need to maintain these blocks? I'd prefer to not, I'd Sooner just run a pair of T's for front and rear and call it good. Does the one with the 2 F's do something to the front brakes wheel to wheel? Like a left/right balance.... Thanks guys
