i have had no problems, mine is a ATO one from the states
i hear the TCI's have drama's though..
i think the biggest problem with useing the brake is the c4/c10 housings braking between the bullhousing and were the dipstick tube goes in the earlier c4's with the tube in the case..
i spent a bit of time deburing mine and got the case shotpeened to help with fixing any small sharp edges and weak spots etc..
thanks for the compliment about my cortina as well i appreciate it
