Front calipers are F250 big twin pistions, and rears are chevy K20 front calipers....so i need to move lots of fluid!
I got a remanned booster for an '89 XJ, and a MC from a '79 chevy K30. I went w/ the K30 MC over the E350 van one because the chevy one clearly had a larger bore and it mated up perfectly to the booster. The E350 one wouldn't have worked with the XJ booster i got without serious work to the pushrod length.
mounted up the booster, tightened down all the bolts...seems as if the very top/back of the booster is touching the firewall, but i can't tell if it's touching hard enough that it's not mounted flush (all 4 nuts seemed to tighten down the same length on the studs), or it may be sitting perfectly flush against the firewall and top is just barely touching and not affecting anything. Anyone else have that little of clearance to get the thing to fit? Or did i get a weird XJ booster, especially since the E350 MC would certainly not have worked with it and everyone else claims that the two bolt together just fine.
I've gotta get fittings/lines for it tomorrow....should i get an adjustable proportioning valve also, or have you guys had good experiences with just hooking the lines up directly to the MC? Also, which lines go to which hole in the MC? front calipers to front output, rear to rear...or opposite hookup? seems as if the rear of the MC has a larger reservoir, but the front output has a larger diameter hole for the fitting, so i'm not sure which one to hook up to which end.
Obviously all ABS is history...can i pull out the little computer looking thing that's mounted on the inner fender just behind the headlight that's labelled "electronic brake controller" or something...seems like it's useless weight on the dragstrip at this point, or does this thing have another function besides working the ABS?
more questions to follow i'm sure.
BTW...i know squat about brake systems!!! :finga:
