1989 Chevy OBS regular cab here and I am PERPLEXED. Here's my situation. I replaced the OEM Master Cylinder (MC) with a Little Shop Manufacturing MC in which the fluid reservoirs are opposite of OEM. i.e. Large is now in the front and the smaller one is now closest to the firewall. I also did an ABS delete according to this link.
Result....shorter brake pedal travel allowing for much improved response BUT, my stopping distance has noticeably increased as if the front discs are too small and there isn't enough fluid pressure to clamp down no matter how hard I get on the pedal. There just isn't enough stopping power. Additionally, even after I stomp on the brakes they wont lock up and despite all the great advice and how tos here in GMT, I haven't been able to determine if the reversed reservoirs are the cause of the diminished stopping power or I have something else going on.
Does anyone else run the LS Mfg MC on the Disc/drum setup or is the LS Mfg MC designed to only work correctly with the LS Mfg rear disc conversion?
SETUP: LS Mfg MC, OEM Proportioning Valve, OEM Front Disc, OEM rear Drum. ABS Module & Antilock Pressure/dump valve deleted
Front Disc Fluid path: Rear outlet of MC (small reservoir) --> 3/16 line to top front prop valve --> 3/16 line out bottom front of prop valve --> to T-block --> to front discs
Rear drums Fluid Path: Front outlet of MC (Large reservoir) --> 1/4 line to top rear Prop valve --> 1/4 line out of bottom rear of prop valve --> to rear drums
