Robinson brake / Wideline Frame

steko · Dec 27, 2018

Good evening,

Does this Robinson brake correspond to the period of a 1954 wideline frame ?

Per the advert:

"Design loosely based on the Eddie Robinson designed double sided 8" drum brake of the mid '60's."

Well I would hope they are only loosely based on the original, certainly if the original that I had some years ago was anything to go by!

It was a pretty awful thing. Consensus of opinion was that the choice of alloy for the hub was wrong. The thing expanded so much when hot it was impossible to deal with, I set it up dragging, but after 4 laps or so the lever would pull back to the bars and I had to adjust it whilst riding. Then, when cooled after the race the brake would be on pretty tight and need the adjusters backing off again!

I doubt this would ever surface as an issue with road use though to be fair.

Like a lot of manufactures did in this heyday-they used the wrong type of alloy thar expanded too much with the heat . . . . . .

Steko, I don’t think this 4ls brake was available in 1954, however it was certainly used on a number of period cafe racers over the years. I have one that I am going to use on my Ironhead Sportster engined Slimlne special.

I have one on my T150V Triton and it's the best front brake I've had I can stand it up on the front wheel,I can't comment under racing conditions but I've had the hub to very hot and no cable issues

Interesting !

Maybe they didn’t use the ‘wrong‘ alloy… maybe the just got whatever was in the smelting pot that day… and maybe yours was made on a day when there was some decent stuff in the pot… and mine wasn’t…?!

EARLIER , the 7R brake was considered ' the BEST ' must be repro ones 'off the shelf '

Twit broke his neck riding a Honda, so they said .

The SLS , no racing , has rather better FEEDBACK , plus it's ' ELECTRON ' ( magnesium alloy , so lighter , tho inflamable , so if it overheats

)

( just kidding ! ) You wouldnt think it'd be safe to let blokes like this loose on machines like that , now would you . ?
