I hate to add to the plethora of mastercraft trailer brake threads, but I have a question and have not found the answer as of yet. When I tow my X-30 and apply my truck's brakes, the trailer brakes indeed engage, but the trailer really slams into the back of my truck before they engage. Is there a way for me to adjust them so they engage a little quicker? The actuator is made by Reliable. Currently, I have a bolt locking the brakes out, but now that cooler temps are rolling in, I'd like to resolve the issue. I should mentioned, I've checked the brake fluid level and it is full.

Here is a picture of what my trailer looks like:
