* Instability: Even with the motorhome jacked up, the weight distribution is significantly altered. Putting it in reverse, even slightly, could cause it to roll or shift unexpectedly, potentially injuring you or causing damage.
* Transmission Damage: Attempting to manipulate the brakes by using the transmission in reverse while the vehicle is jacked up could damage the transmission itself. The drivetrain isn't designed for this type of stress.
* Brake System Damage: Forcing the brakes to adjust this way could damage components of the braking system, leading to brake failure.
* Improper Adjustment: This method is unreliable and unlikely to properly adjust the brakes. You risk making the adjustment incorrect, potentially leading to uneven braking and further safety issues.
Proper Procedure: Rear brake adjustment on an E350 motorhome (or any vehicle) should be done according to the manufacturer's specifications. This usually involves:
* Accessing the adjustment mechanism: This is often a star wheel adjuster located within the brake drum or on the caliper (depending on whether you have drum or disc brakes).
* Using the appropriate tools: You'll need specific tools, not just a jack and your transmission.
* Correctly setting the adjustment: This involves turning the adjustment mechanism until the brakes have the proper clearance. You'll likely need to check the brake pedal travel to ensure correct adjustment.
Consult your owner's manual or a qualified mechanic. This is not a DIY task for the inexperienced. Improper brake adjustment can be dangerous and lead to serious accidents. It's far safer and more effective to have a professional mechanic address the brake issue.
