So my master cylinders gave out causing a nice paint stripping leak all through the driver side footwell. Anyway, everything in the hydraulics was looking pretty rough so I decided to do a modest refurbishment of the whole system. Anyway, when I pulled the front brake drums I noticed that I didn't have the typical 10" drums that a 67 88" IIa should have. I have 11" drums with the 109" style wheel cylinders (already bought a IIa kit for an 88"). I haven't pulled the rears yet to see if I have 109 style brakes on the rear which would take the 10" IIa style front wheel cylinders so that my kit wouldn't be a total waste.
Anyway, what really has me confused is that my front wheels have two wheel cylinders per wheel, one on top and one on the bottom. I thought that there should be a single wheel cylinder with a pivot on the bottom. This two-cyliner setup does not show up in my IIa manual. I am new to drum brakes, so bear with me.
Any thoughts on this? I assume that I just need to buy 2 pairs of wheel cylinders per wheel up front (I'll figure out the rears this week). I'd just like to understand if this is a common setup or if somebody has done something custom to it at some point in it's life.
Any help or thoughts would be greatly appreciated.
