Title: Adjusting a TLS brake
Post by: DEAN SOUTHALL on 19 March, 2017, 11:45:06
I am now ready to assemble the TLS on my A10. The machining and welding is done so lets hope it all lines up!

For now though I need to know how to adjust the brake arms to be sure its operating as a TLS and get optimal performance.
Intuitively I am assuming that with the rod that links both brake arms disconnected I operate both brake arms fully manually untill then and with my third and fourth hands adjust the linking rod.

Does anyone know of a better approach or the BSA recommended method?

I use the third arm method - with the assistance of my Wife.

The Pitmans book of BSA twin suggests disconnect the tie rod apply the brake handle bar lever and keep it in position with an elastic band. Then apply the rear lever with spanner and adjust the tie rod.

The factory manual procedure is in the photos but you need to deal with the effect of the return spring on front lever.

having adjusted the tie rod dont alter it after linings have bedded in.

Many thanks for that Julian. So prompts the metaphorical ink was still wet on my post!

I'll get onto it next weekend as Mrs and I off to Pembrokeshire for a few days...now where are those waterproofs!
