This is a relatively common conversion for TR4 vintage racers who need to
convert to a dual circuit brake master cylinder and are trying to save some
$$$. You use the master cylinder with power booster from a TR6, but to do so,
you also need the TR6 peddle assembly. Another requirement is that a 3" hole
needs to be cut in the firewall, which then needs to be reinforced around the
The TR4 parts manual shows that back in the day, there was a booster available
that fit the TR4. I have seen it referred to as "Moto-Vac" and as "Power Stop"
vacuum servo kit (part #514600). I have never seen one.
