front brakes upgrade

 I think I ended up using a 19mm master cylinder. This is the third cylinder I've tried, the pedal effort is quite high but it does stop OK if you stand on the pedal.

You have to make that choice with the master cylinder bore diameter.

Larger bore = more per pressure but less peddle travel.

Smaller bore = less peddle pressure but more travel. 
 

I prefer a smaller diameter and a touch longer travel, I find on a car with no ABS or servo the travel is small anyway because it’s so direct. The brakes in my kit are quite good, I swapped for a smaller diameter master last year and it’s a big improvement on standard. 
 

It’s important to line the push rod and master cylinder accurately too, a straight push is much more efficient than if it’s at a bit of an angle because no energy is wasted in angular motion, and less in friction.
