My kit came with a sigma booster and ford master but as you would recall the origin of my kit and its bits, that these items were probably sourced by the previous owners than GF. I'd need to check the old GF receipts to confirm this and I'll let you know either way.

Anyway, beyond having a layer of muck on pads and rotors, from sitting around for tens year, my drives and the braking needed have not generated the sort of reaction you are describing.

I've corrected a long brake pedal feel by adjusting the pedal linkage but haven't had another opportunity to test drive. Don't expect any difference in the braking force though.

You need to figure out what the master and booster are from and work the calcs for bore size and effort much as Aussie Mike has talked about in previous threads. But I'd tend to concur with the initial response that maybe something is sticky or not quite working right yet!

Cheers
