Brake connectors again

Gentlemen!

After making perfect flares after a lot of practice I have struck a wee problem.

The M10 connector goes into the caliper fine, but when i went to connect it to the three-way it was the wrong connector. What should I be using?

In the photo, from the left, I have the original an M10 and a UNF just for comparison. What is the one on the left?

They will be either 3/8 UNF or 10X1. On a Classic i would think they would all have been 3/8 UNF. From memory think it depends whether the brakes are Lockheed or Girling. You will have to get some of each and screw one in to find the correct one. 10mm should not go in a 3/8 union. But a 3/8 will screw into a 10mm one but could strip out so be careful.

are you sure t piece doesnt need concave flare which requires a second operation rather than convex flare that fits caliper

The steel pipe that came out (broke off) had a mushroom flare. Do you think it prudent to see if there should be a concave? The pipe was original factory though.

The Calipers are Lockheed type, but the m10 seems to match the ones that came out no problem. It is just at the T-piece where I have the problem.

Daft question, but I assume the 3/16 brake pipe uses the 3/8 fitting?

I might just get every connector in Christendom

have a look in the bottom of t piece has it a cone poking up or further in , t pieces can be either

nah, it pokes in , so it appears the mushroom was/is correct.

All brake pipe is still 3/16, 4.8 mm as far as i am aware. Unless someone snuck 5mm in at some time.

Great, thanks for the help!

The early classics used the imperial system - the master cylinder flange to the brake servo is vertical. Some time later in the 70s they swapped to a metric system. This is identified by the the master cylinder flange being horizontal. The imperial master cylinders became unavailable, so if you wanted to replace it you had to convert to metric but I can imagine that lots of cars were only part converted, with the pipes becoming converters between metric and imperial systems. Maybe yours is like this ?

I'll check that out, thank you, but mine is a 92 model year. The guy I bought it off said I would be tearing my hair out. Luckily, I'm bald!
