Message: [QUOTE="Tiha, post: 1549803, member: 33189"] Well, since I have single piston rear calipers currently I use a master cylinder from a 99 expedition. piston volume in cubic inches is very close to the setup I am currently running. The expedition had dual piston front calipers and single piston rears. It definitely made the single piston calipers work correctly or at least working a lot harder than they were. I have tried the OEM master, the super duty master that the hydroboost came from, and an E350 master cylinder. I think there was one other odd ball too, smaller bore to increase pressure with less pedal activation. the Expedition by far made the rear calipers work the hardest and braking the best. my front pads are something fancy I bought with drilled and slotted rotors and I am starting to think they are junk and not grabbing worth a crap, but then maybe it is hydroboost not working correctly. It panic stops well, but daily driving I think pedal pressure is way too much as well as steering effort. I took some caster out and it helped a ton but I shouldn't have to do that. I just shouldn't have to push so hard on the pedal for normal stopping. My focus right now is to reduce pedal effort, I think that result will reduce steering effort. just not sure whether to port hydroboost or try different steering pump first. May end up doing both. After that will come the 10.5 swap debate. I remember toe touch hydro boost growing up on big trucks. You barely touch the brakes and it is stopping. This setup now is ridiculous. [/QUOTE]
