rear brake pedal identification

[mark]

Can anyone help identify the rear brake pedal that came with my 55 road rocket basket case. It has the number 47-7014 cast in. It fits onto the frame ok but doesn't clear the footpeg. It looks very similar to the one shown in the parts catalogue but has 2 adjustable bolts on the vertical arm instead of one. I think that I can bend it to make it clear the peg but I would like to know what model it's off first.

Mark,
             I think it probably came off a B40.
I have seen these at swap meets but always left them behind.

yep,
It will be from a Victor framed unit single that uses the button type brake light switch.
One hole for the stop and the second for the switch activation bolt

thanks for that info. I think that I will modify it and use it untill I can find the correct one which seem to be scarce.

Way in the back of what is left of my mind I seem to recall that they don't fit very well.
Think that it will foul on the primary.
Let us know how it goes

what you may be remembering is that the boss for the top bolt fouls on the swingarm spindle retaining bolt which should be ok when I grind it away. It basically needs to be bent out near the pivot by about an inch to clear the splined end of the footpeg. What I would like to know is what length the pedal should be so if anyone has an original 54/55 one that they could measure say the distance between centre of pivot to rear edge of footpad or any easy to check dimension I would be eternally grateful.

Mark (Hello namesake! Well, almost...  ),

Being unable to source the correct brake pedal for my '55 Shooting Star I altered one off an M20 (cutting off a bit of the footpad to make it narrower, welding on a threaded sleeve for the stop bolt and a little heating and bending did the job).

However, it now fits perfectly okay, with the right length for good operation, so if it helps you I will measure it for you. Please be aware that it is not the original one, but at least it's a starting point.

Best wishes, Markus

Two pics for you.
Sorry, don't have an imperial folding rule. The one on the photo shows centimeters, so watch out!.  

When taking the pics, I remembered that I also shortened the arm for the brake operating rod. The distance between the pivot point and the brake rod mounting hole is approx. 65mm, so that the brake rod is running parallel to the swing arm.
I took all the measurements I neede for the modification at a friend's Goldie.

Hi Mark,
theres a modified original on ebay motors at the moment no.330445269702

Here are some dimensions from the pedal I got recently
11 1/2in. from pivot centre to centre of bar that pad is welded to!
2 1/2in. from pivot centre to rod centre
the pedal (centre of arm) passes  1 1/4in. outside the end of the splined tube, but continues out at an angle to pass the primary case
there is a photo of the pedal on my wanted LH footrest post,
I cannot read the part number on the pedal or on the other one on the SR (baskard!!) on the bench

Mark,
             The forging number on the pedal is 42-7004.
You may have a great deal of difficulty finding one as they were only used in '54/'55 on the A7,A10,B31 & B33 as well as Goldies for all years and RGS.
They are in great demand for the "original" Goldie "restorations"

Mark,
         You could try Mike Reilly in Brisbane.
Draganfly have it listed but pretty pricey as do British Only in Austria.
The illustration in British Only looks a little iffy but if going down that path I would contact them and ask a few questions.
Part number, if you don't know, is 42-7005

actually Trev it's 42-7003 and yes I will try Mike. However this one is so close to the proper one, the lengths check out ok that I think that I will bend it to shape anyway as an exercise because it's always handy to know what can be successfully modified to suit. Also the left footpeg that I have has the casting number 42-4805 and the parts book gives 42-4840 as the part number, what have I got?
Regards
Mark

Mark,
         Sorry about the number, I was getting back to front with casting and part numbers.
Part number is one below casting.
42-4805 on the foot peg is correct for 1954-57. The splined distance tube is longer than for the later models.
Right hand is the same for all years.
Trev.
