Slide out stuck and resolution

I call it a brake but some say clutch since it works like a clutch by applying pressure to the locking mechanism. No matter the problem is that a failure of a low cost part requires a total replacement of the motor, gear and brake when the failed part is easily replaceable. That is why I tell people who are not mechanically inclined to stay away from RVing unless they don't mind being ripped off for service by an industry that is based on gouging its customer base. Even if you can fix it yourself you can still get burned on the parts. I always look outside the industry for parts. My bathroom faucet from an RV store was $50.00 Home Depot $12.00. RV dealer labor $90.00/hr 1 hr minimum. Mine free and it took 15 minuets.
