Title: 1939 B21 - B26 rear brake pedal stop plate 65-7023 dimensions / drawing
Post by: Inbits on 03 Dec, 2020, 22:49
Hi, anyone out there have the dimensions of the stop plate, or one for sale? I see it fits the 250 and 350. The M series version looks different and the mounting holes appear to be spaced differently as well. Just thought I'd ask the question and try and get it right before taking to measuring the frame mountings then guessing the missing info that's not apparent. Thanks, Garry

Hi Garry,

Here are some photographs of my B21 brake stop.   

Sorry, didn't have time to do a fully dimensioned engineering drawing so I hope you can get what you need from a steel rule held in place with magnets!   
David Bailey didn't take the photographs either .....  ;D

Hi Alan, Thank you, I am very grateful for the time and effort you have taken doing the photos and replying. They're perfect and will take the guess work out of the job! I'm sure I can sort something out now which will be at least satisfactory, until one day I may come across an original.  Thanks again. All the best Garry.

Hi Garry,

I did just put the Vernier on the "bent arm" yesterday;  it's 12.5mm wide by 4mm thick if that helps?

Cheers

Alan

Hi Alan, it certainly does help, I've got no excuses for getting it wrong now! Thank you once again, very good of you to go to the trouble.
All the best, Garry
