Another point of interest is that the clevis fork for the brake pedal is a billeted item, not a pressed steel one as used for the clutch pedal. Apparently this is because the pressed steel one could fold up when big enough brakes and master cylinder are fitted, as the pressure needed to apply the brakes is so great. I don't think this would be an issue with my Mazda brakes, as they are only single piston floating caliper jobs, but better safe than sorry.
Embarrassingly I couldn't find the clevis forks in the kit, so asked Westfield to send me some with the set screws mentioned earlier. They duly did, only for me to later find they were in the kit all along. Oops, sent the new ones back to Westfield, as the billeted one particularly is obviously quite expensive.
Below are some pictures of the pedal assembly, and fitted master cylinders. Onto the next job of fitting/bending the brake pipes.
The first picture is looking forward at the pedal assembly.
The second picture is looking from above at the pedals. Note the billeted clevis fork for the brake pedal.
and finally as you can see from the packet the pedal rubbers came in, they are the self same items used for many British Leyland cars, all the way back to the Marina!
