Hello Vijaydandur,
As you have had no adverse effects of the sudden braking whilst on the motorbike there is very little chance that you have damaged the repair. A compression force of your arm against the rider in front
would not have injured the shoulder. If you are going to be on the bike in future, be aware that movements of your arm backwards eg reaching behind you or if the bike suddenly accelerates causing you to
twist and stretch your chest muscles at the front of your shoulder could cause excessive elongation of the repair. It should not be possible for this to happen with the sling. The little bit of pain you felt may be
due to a quick contraction of your muscles whilst bracing - a reflex action.
I am glad to report that you should be fine after your scare.
All the best for a full recovery.
