Unable to regain speed after refueling

After getting gas in Alabama (from Michigan), we got on the on-ramp to I65 and started to speed up in order to gain access to the highway. We were unable to accelerate. Felt like brakes were applied. Pulled over to the shoulder and attempted to move vehicle forward and in reverse and again felt like brakes were locked up. Could this be a problem with the drive shaft parking brake system on 1993 Chevrolet P-30 chassis or does someone have another idea. The RV is in a shop in AL pending diagnosis. Any help would be appreciated.
  • Check to be sure front brake pads are not stuck. This was a problem on the P-30 from failure of the rubber brake hoses to the wheels going bad internally and not letting the fluid return from the caliper.
  • Sure sounds like the auto park brake system that acts up on the P30's.. Had that issue several times on our 98 MH with the p30 chassis. There is a switch that controls the brake on the drive shaft. It is nick named the "rotten green switch" as it is notorious for going bad and letting the fluid leak. Once enough fluid leaked out it allowed the parking brake to lock the drive shaft. Not hard to change. Last one I bought was about $65 at Chevy dealer. Had so much trouble with them that I learned to always carry a spare.

    Did you notice if your brake light was on or flickering when you had the problem?
