Okies, Today I contacted a brake conversion company here in Brisbane.

They are VERY familiar with Jag brakes and of the opinion that the excessive front brake is caused mainly by a mismatch of componentry.

When asked what the RMC brake system comprised I answered with:

Mitsubishi servo
Ford Master cylinder
series 11 4 spot front calipers and Jag 2 spot rear calipers.

His response was immediate. The ford master cylinder incorporates a proportioning valve. The Jaguar did not incorporate a proportioning valve as such. It used a dual servo to apply a different assist for each end of the car.

He feels the problem can be overcome by using a master cylinder with no proportioning valve but then also play with different cylinder sizes to get the bias correct.

Does this make sense to any-one?
