Looking for more information on the topic. When doing non-Toyota clutch swaps it is often said the Toyota clutch master doesn't move enough volume to get full disengagement of the clutch. Some swap in after-market clutch masters with larger bores but I'm looking at keeping the original look if possible.
I'm working with a '73 FJ40 which has a 3 bolt flange on the clutch master cylinder and 3/4" bore. In my research I found that the '58-'70 brake master cylinder also has, what looks like the same, 3 bolt flange but has a 1" bore. Now before you jump the gun and say there is one too many outlets on the brake master you will be wrong. The early brake masters only had one 10M x 1.0 outlet.
So, I'm thinking this might be a perfect candidate for my conversion.
Now I know that when you do a disc conversion you have to remove a valve from the brake master. What I don't know is if the early brake masters also had these valves which may leave too much pressure in the line for the clutch slave cylinder.
Any information would be greatly appreciated. I also may have jumped the gun and purchased a Raybestous unit from Rock Auto at a crazy price. This is the unit:
About the only outward difference with clutch masters is the line attaches at the front. I'm just hoping the mounting bolt hole spacing is the same as the clutch master as there was no information on line about this.
