Hi Folks im messing around with a front brake from a conical (the one with the air scoop ) to see how i could make it fit using the current Harley brake arm setup to try it out. if i position my front wheel slightly closer to the brake arm side causing the wheel to be slightly off centre, can i take it that it will make for poor handling,cornering etc.??

it won't help, for sure. The only reason I can see to do this would be the alignment of the anchor arm, I would have thought this could be resolved using a shouldered bolt at the fork leg?
Shoot, a man could have a good weekend in Dallas with all that stuff...

lossen spokes, offset rim required amount, retrue, ride (you should be able to get 1/2-3/4" offset without replacing spokes)

yes 45 brit , it is for the alignment of the anchor arm - maybe a longer shoulder bolt would do it as its only offcentre by 1/2 inch or so.

Ralph - as the wheel currently is true - i'd prefer to leave it be if possible.

if the anchor arm is a special piece, which I assume it would be, could you not spilt the misalignment between a shouldered bolt, an additional washer at the brake plate and a small offset in the arm, just crank it a few mm?

im gonna use the original harley brake arm/shackle 45brit . when i turn the brake shackle around facing inwards toward the brake plate it helps a bit and i might get away with a few spacers - and "splitting the misalignment" as you suggest , its still all conceptual anyways at the moment, as im trying to combine different wheel bearings on the BSA wheel but using a harley axle also. My access to tools is limited so im seeing if i can work with what i've got !.if i ever get it to work i'll post a pic :)

careful !

two "fake-twins" arms :
the WLA and the WLC( big-twins also )

they look identical

but are NOT with the same offset .

so :arrow: :arrow: :arrow: :arrow:

are you SURE you get the good-one ??? :?: :?: :?: :?:

Hi Fran -6
not sure i understand will you explain further please, im currently using the WLC big twin setup and i want to use the same brake shackle for the new setup also , iwill also mount the Harley Pivot to suit the big twin shackle onto the BSA brake plate.

Am i sure i got the good one ? i'll prob only find that out when i take a header out over the bars :shock: :)

fran-6 is saying that there are several brake anchor arms for different applications which look similar but vary dimensionally. The WLA and WLC brakes differ in that one brake is built into the wheel in a manner similar to a BSA, while the other one is a detachable unit like a Big Twin and the brake plate offset and the related anchor arm varies "according" . The Big Twin brake assembly looks the same but varies a little and again, has a brake arm to suit.

I didn't suggest this because very few people have the parts available to compare them side-by-side and choose the one with the best fit, I was assuming you had the shackle from the original bike and would go with that.

ya gimme a doubt ...

but i am pratically sure the WLA and WLC brake-arms seems twin-bros , but aren't the same

it's not a question of shape

it's a question of offset .

i'm gonna check this ...
