Brake Issue

[Angryacres]

Hi,
Im new here and noticed a problem with the 813 airbrakes this weekend. They were fine in the fall the last time we ran it. it had more than half a pedal stroke. Now the pedal goes almost all the way to the floor. On startup the air pressure alarm goes off when there is suffificient air pressure on the gauge. I don't know the truck well enough to know where i should be checking first. All air outlets and such seem closed. I would appreciate any input. Thanks

Have you converted your 813 to air brakes?

Did you check the fluid in the master cylinder? It has a habit of 'wandering off' if the truck sits for an extended period. If you have a bad wheel cylinder, that is one of the places it wanders off from, and it's not always immediately obvious from a casual look.

Cheers

From reading the first post, I would suggest you read the -10 BEFORE you drive the truck again
