Had just hooked up our 38' - 12,000lb fifth wheel and headed out for the weekend. Came to the first stop sign and the brake pedal went to the floor. Luckily got stopped with trailer brakes. After stopping, pumping brakes caused brake fluid to pour out from just in front of the driver's side rear wheel. Upon research when we arrived home, I find that this is an ongoing issue with Chevrolet trucks.
I was unloading mulch from the bed of truck onto the flower beds in my yard. When I got back into the truck to move to a new spot everything was fine until I went to stop and the brake pedal went to the floor. The truck was only at an idle but the brake wouldn't even slow it down to a walking speed. The parking brake worked fine and the truck came to a stop. I put the rest of the mulching job on hold until the next day until I could figure out what had just happened and how to deal with it. The next day I checked the brake fluid and added almost a quart. When I went to move the truck the brake still went to the floor but I was ready for that and got the truck off of the grass and back out onto the driveway. That was when I saw just how bad it was leaking brake fluid and the truck is still here at my house. I guess I will have it towed somewhere to have the brake line that runs down the left side of the truck to the rear wheels replaced.
