Re: CAUTION ON THE USE OF SILICONE BKAKE FLUID IN ESAMATIC BRAKE SYSTEMS

The NOS compensator valve was amongst a box full of NOS brake parts which I inherited wth the 56. The parts were NOS from one of the two Australian Packard Dealers in 1956. IRA BERKS in Sydney. It was not in it's original packaging but had no seating marks on the seal to indicate that it was used. The break was clean and I can only assume that it had been stressed during storage or was faulty from new. I doubt that it would be a common fault and I was amazed to see the part broken. The interesting thing about the pressurising of the brake system is that towards the end you could sit in the car after driving and watch the light come on after 5 minutes, without touching the brake, indicating the role that the compensating valve has in allowing the expanded system fluid to escape from the master cylinder to the reservoir. I am going to recondition one of my spare Treadle -vac units with some of the same NOS spares and be a bit more observant this time. Peter Toet
