brake pedal pressure gone after winter parking air pressure ok
Started a new thread, then thought it would be better continue this since it deals with similar problems.
Subtitle says it all. Started to work on the truck, build up air pressure, pushed the brake pedal: nada nic nothing zilch. Like the pedal is not connected to anything anymore.
The system was flushed, all brake lines replaced and properly bled a few times in June 2011. Brakes were ok when parked here in June 2012 (16 months ago), and when I moved the truck back and forward a few yards in November 2012 when topping up the cooling fluid. Now nothing.
I do have a crack in the air line to the front connector for trailer or towing and I can clearly hear air escaping. However, that crack I already knew about last year about and it emptied the air tank quickly but should not influence the braking like this.
The puzzling thing is that the truck was parked with 100% functioning brakes and now suddenly is without anything. No visible oil leaks below the car, but it is standing on grass so if there was a big and quick leak when parking, 18 months ago, the signs probably would be gone already.
I had to drive the truck back and forward a few yards again to get it onto some wood prior to raising the truck and change the tires and check on the steering. Quite a problem to do that without brake. Even knowing I had no brakes I still got this empty feeling in my stomach when the truck overshot the wood and I automatically tried to brake (nothing to hit there anyway, but still).
I will get back to the truck today
to work on the steering, and will look into this as well, check again, including fluid levels. Probably a faulty MC but any preliminary ideas how this can happen with a parked truck??
