[Healeys] 100 front brakes

[Hank Leach]

Gary- The note about the type of thread used was what I was referring
to-mentioned earlier. The early BN1 used AF type threads.(equivalent
to a 1949 Chevrolet). All the later cars (and I do not know where the
changeover was-maybe Michael does) had unified Girling threads. The
lines should thread easily or else you have a different thread count
and pitch. I don't think you will find the early type hoses from any
supplier. They will have to be special made or found in NOS. Hank

  This car is a BN1. Yes, I was referring to the brake wheel cylinders
or slave cylinders as opposed to the master cylinder. What are you
referring to when you say "Be sure that you were supplied the correct
threaded hose...most suppliers do not have the early style." How do I
identify an early style hose from a latter style hose?

  Do you mean "wheel" cylinders and not "slave"...100s have a
mechanical clutch. I understand that on all model Healeys the brake
hoses have one threaded end and one flared end. That flare goes into
the metal line nut. 
 On the early 100 wheel cylinders they used an American AF thread but
switched over to the Girling unified thread on later releases. The
bleeder connection can be either in or out in shape (photo) but if the
bleed screw is flat it uses the check ball (supplied in rebuild kits)
and fits the recessed shape. The pointed bleeder uses no check ball.
Be sure that you were supplied the correct threaded hose...most
suppliers do not have the early style. Use Girling red grease on the
threads. Hank

  I will be assisting a friend to replace the flexible hoses on his
100 front brakes. He has ordered and received a set of hoses, but the
ends that thread into the slave Cyl do not match the shape of the
mating surface in the slave. The ends of the hoses are flat & it is my
understanding that the cyl. is cone shaped inside. The vender says
this is not a problem. I think it is a problem. What do you say? 
Also, if it is an issue, where can we get a set of flex hoses that
have the correct ends for this application & are also the correct
length (I.E. Not too short)? Gary Hodson
