Cable modifications for servo'd minis
Modifying the heater cable on brake servo assisted Minis,
If the heater on these Minis doesn't get hot enough (or does not give cool air), check the connection on the heater valve in the engine bay. The cable is only hooked in the valve, so it is not possibility to adjust the travel of the valve as on the old Minis.
The valve lever travels a distance of about 28mm. But sometimes the cable does not make the same movement. The only way to do an adjustment, is to measure the amount the cable moves. Let's say, it's doing 25 millimeters. So the difference is 3mm. Cut those 3 mm (better 4) from the outer cable.
In this way you have increased the travel of the cable.
The latest minis are 'pull for hot'.
