Sintered iorn ( honest to god Ceremetallic 60 year old lining!) rear shoes. </div><div>Additionally it's a rib case with 1275 slave cyl..</div><div>I have had & still have a great pedal pressure with no surprises and am using DOT 6 Silicone fluid. </div><div>All that useless rambling , the car has pretty darn good btakes and clutch actuation. Yes it's not a 5 speed with a Datsun clutch. </div><div>But! Where I AM going is this. About 10 years ago I completely reconstructed a 1969 Elden PH10 Formula Ford from a bare frame up. The 2 brake master cylinders & clutch master cylinder had to be replaced. There was a serious pedal feel to brake response and another odd ball " the clutch always felt funny" stated by its owner. The car was started ( disassembly) years before I inherited the project. Parts were lost and hydraulics corroded , that said I had to replace missing master cylinders. I am not very good at the math in determining the volume of a cylinder relative to the volume being moved in another cylinder to increase or decrease pedal pressure and also determine pedal travel ( which kinda has a lot of where the push rod attached to the pedal relative to the pedal pivot point). </div><div>There is / are a lot of available tables to do the " how big moves how much" calculations. Yes and pedal free play at master cylinder piston at rest also effects the efficiency of the operation.</div><div>One last " this might help" thing! As far as rear drum brakes go , fully apply the emergency brake when bleeding the brakes. Ot does not replace fully adjusting the shoes! It simply removes the possibility that it's a poor rear show adjustment question. </div><div>So? Ummm...next?</div><div>Chuck</div><div><br></div><div><br></div><div><br></div></div></body></html>
