I just fitted my park and with the bike on the centre stand thought I would see how firm I needed to set the park brake only to find the my hand brake was not operating on the back wheel at all. Jacked the front wheel up and checked that the foot brake was operating on the front wheel and that was OK.
Has anybody tested theirs?
Just wondering if something was not done correctly when it had the brake recall done on it.
Mine is a 2008 model

Does the front wheel need to be turning for the combined braking to work???
The main thing, is that the Park brake works

The hand brake doesn't activate the rear calliper directly whereas the foot brake directly operates the centre pot in each calliper.
If the 1300 layout is the same as the 1100 then you will have a secondary master cylinder which is activated by the LH front calliper which in turn operates the two outer pots on the rear.
So any braking on the front wheel operates the rear brake. Even the foot brake alone causes enough braking effort on the front wheel to cause all three pots on the back to work plus one pot in each front calliper.
Confusing; yes, but the picture shows basically how it is set up

Thanks Alan.
I had always thought that the hand brake just operated directly on the middle piston on the rear wheel brake caliper.
So the hand brake will not have any braking effect on the rear wheel when:-
1. You are rolling backwards and
2. Once the lefthand front caliper is not being forced forward by the drag it may be exerting on the front wheel

That sounds right.
The 1100 manual suggests that as a test you should be able to lock the back wheel by manually (by hand) moving the LH calliper forward though I have never tried it myself. The only other thing from the manual is to replace the pads on all three callipers at the same time for the ABS model.

I have used a middleton park brake on the ST1100 non-abs for quite a few years. Never felt that the rear wheel also needed to be part of it. I miss having it so will look at what I can get or modify to use on the Trophy.

Not really concerned about no back brake for the park brake but now realising that the combined braking for the hand brake doesn't work going backwards will have me being more careful backing down slopes. When backing down a steepish driveway on my GL1500 the front wheel simply locked up and I kept walking back with the bike under control until I reach the bottom. Unfortunately there was no gradual transition to the flat so the bike straddled the change in angle my feet left the ground, very embarrassing.
