Folks, I'm having a bit of trouble bleeding my January 1955 car. Bleeding the rear brakes was simple. The nipple needed a 7/16 AF

spanner. When it came to the front I couldn't get a spanner of any size on the nipple. I realise that a pic would be very useful but

unfortunately I must be the only person in the world not to have a digital camera.

 

Do any of you knowledgeable guys have an inkling?

 

Thanks

More information on this bleeding problem. The bleed nipple is on a dog leg. This is attached to the slave cylinder by a 7/16 AF nut. At the other end of the dog leg the actual bleed nipple is attached using a tiny nut. I assume this is the nut to be released and tightened during the bleed operation.

Unfortunately a 1/4 AF spanner is too small and a 5/16 AF spanner is too big. I have also tried 6mm and 7mm spanners with the same result. It's wit's end time.

 

Yours in hope!

On drum braked cars the rear bleed nipples were different to the front. So long since I've bled Lockheed drums that I can't recall the spanner size. Try measuring with a vernier guage or small adjustable spanner to find the size. Beware trying to undo the bleeder with an adjustable spanner though, as it might round the nut.

 

Strangely, 10mm metric bleed nipples were used on some early cars, indicating a continental maker.

Thank you gentlemen one and all. When I got the car jacked up a bit and I could see properly what I was doing the answer (as suggested by Viv - ta) was a

10mm spanner. Job done.

 

Thanks again
