brakes aka vincent

Postby GuyWalton » Sun Nov 17, 2019 8:34 pm

I have seen a photo of a brake system made up from 2 no. 7 inch brake drums joined together somehow and with a brake plate either side . I , probably , have the engineering know how to complete this and I have all the parts but I cant find the picture that I saw of a completed example . It would be a handy reference . Has anyone seen this picture anywhere I have searched the web but to no avail . Thanks .

They were all Ariel parts .

John Jane had one in his SQ4 and Herman Noort in his Mk1.

Have a look at the Royal Enfield Connie parts book........it used a double sided brake on the front........IMHO ,excessive weight ,with the braking swept area better made up by a single mechanism in a 8" or larger drum.

Apart from this you have to fix some kind of abutment to the left side slider.

Some of those set ups end up with little or no spoke angle across the wheel which is particularly worrying for a side car. Vincent's have that problem. Nothing's perfect. The iron drums are much better than steel for brake effectiveness..Nev

I had one of those from a Bill Boddice sidecar outfit. I believe it is on John Bradshaw's Ariel engined trike now.

When the 2 hubs are pressed onto the sleeve it is important to get the spoke hole alignment correct. The holes in one side should align half way between the spoke holes on the other side.

I was looking into that David and couldnt quite tell if it was a 50 50 alignment . Thought id press one side then line up with new rim and spokes to see the correct fit .

I have got on quite well with my twin sider all nice and true and correct size . Getting spokes in is another matter but a little bending and straightening and they will go in . Vincents drawing made it so much easier .
