Brake Pedal Spring Gold Flash

[Shaun]

 Gentlemen i presume there is a spring on the n/s fitted to the brake pedal pivot area on 58 has any one a picture or could point me in the rite direction
i would also like an idea of what the corect brake switch should be
Many thanks Shaun

Shaun,
            The spring is part number 42-4355. It goes inboard of the pedal and clips to the lower edge of the pedal and around the frame above the sidecar lug.
The brake light switch is part number 19-1114. It mounts to a plate on the frame on the rear of the loop.
The switch is the standard rectangular shape used by most makers in those years. You have to watch that you get a "pull on" type.
These parts in pattern form are readily available.

Thanks trevor i will have a go again in the morning ,i have a new spring but couldnt figure it ,began to think it was one i had got for the m21
The switch i have a rectangular one but i see that on most frames i have managed to find photos of have what  looks like a small bracket welded  to the frame at the place you mention to accept the switch i do not have this on my frame i am perplexed and about to have a large whiskey
many thanks Shaun

Shaun,
             Have the whiskey then check your frame number.
The GA7 frames do not have the plate as the switch is mounted on the toolbox.
Your frame should be FA7 if it is '58.
The plate is easy enough to make and tack to the frame.
Shown is the switch and mount on my '58 and the brake pedal spring set-up on my '62. Note the switch position on the '62.

Blimey trevor i must be mad its cold out there !yes the frame is GA7 does it still use the same switch ?
I have the wrong spring it starts of ok at the pedal but has a straight bit instead of the curved part to wrap around the frame i have the old one or think i have but this is way out of shape !
Thanks again, looks like you have cleaned it

[trevinoz]

Shaun,
               Have a look again at the brake pedal picture, it is on a GA7 frame.
The switch is the "D" shaped object above the pedal with the arm projecting.
Not cold here. Raining and 27 degrees.
I haven't cleaned either bike. The '58 is a long way from finished and the '62 is waiting for my mate to paint the tank.
I can then finish it. They are both covered in dust!

I see the switch now didnt recognise it as one none of the parts books shows anything like that got a jumble coming up so will be able to get both i hope,put some oil in the tank today tempting to start it in the next few days .
Many thanks again Trevor

Shaun,
            Another thing. Check your brake pedal. The '58 will have a hole for the switch spring and the later will have a dowel for the lever in the same place.
Good luck finding a switch for the later frame. They were complete garbage and didn't last.
Also they come in several different forms. The one I have isn't original but a different type that I modified.
There is also a rubber boot to protect the works from the weather.

The  new spring i was looking at was a kicksart spring der !in the cold light of day ,all be it a few days later, its so bloomin obvious,i have checked the frame no- firstly i dug out the log book the frame no is CA7153--- listed as 57 in the log book i have looked at bsa dating site but am not getting it ? help ! the engine no seems correct ,the brake pedal has a stud on top this i believe is the later one i think my solution is to make a back bracket for the earlier one but why is the welded one missing? this brings me back to the identity of the frame i have powder coated the frame and gave it a 2nd hot coat this has made it extra thick and can barely make out the letters the c could be a g but i dont think this would be sending me in the right direction for identifying and i am reluctant to remove the powder coating thus far
I bought the machine because it has a Blacknell 2 man sidecar this was great for us to holiday around france in as a familly and was sold as a gold flash so ?!
Happy new year to all
Shaun

Shaun,
             If your frame is CA7 153, that would make it early 1954.
CA7 frames didn't have the sidecar mount in the rear loop as shown above.
A frame that early would not have any cast front engine mount lugs on the front down tube, only 4 tubular lugs.
All frames except GA7 have the switch mounting plate welded to the loop.
A '58 frame should have an FA7 prefix. The Flash engine number prefix became DA10 for 1958, CA10 before.
Does your rear brake lever on the brake plate point up or down?
Up with the cable adjuster in the casting on FA7, down with the cable adjuster in a fitting on the torque arm anchor point on GA7.
After all this time and probably many disasters, you could have anything.

Hi Shaun,
You could always mount a universal switch as LJ has done here
http://www.a7a10.net/forum/index.php/topic,2160.0.html

My 61 SR should have the D shaped switch, beware there are several variations if you can find one
It took me a long time to get the correct one, up till then I used a flat plate bolted to the hole in the toolbox
on this I mounted an industerial micro switch with lever,

The engine no is DA1071-- and the lever on the brke plate points down the lug for side car is not in the hole s per your pic Trevor
I do have a universal switch i could maybe fudge up John
just a thought should i run bike in without the sidecar on
many thanks shaun

[Shaun]

Thought i best add some pictures Trevor to see what your thoghts are on the frame there is a bracket on the tube under the tank would this be another head steady do you think
thanks Shaun

[Shaun]

sorry didnt get them all first time

Hi Shaun...

If your considering running in the engine while bike is solo, Do be extremely careful while riding with those Avon Triple Duty tyres! They are not cornering tyres and I almost guarantee you'll be off, especially in wet weather and or snow/ice. Probably also the front fork springs will be of heavy duty and you'll know about it when going over bumps and holes. If you are able to ride bike with sidecar and not with lots of ballast, and sidecar is reasonably light, then I suppose it might be okay to run the engine this way. *Experts correct me If I am wrong about this*

Cheers!
