air brakes

Are your brakes air over hydraulic or straight air?

Do you have a treadle valve?

Curious; How can you operate the tractor without using any brakes?

hi Bob- I think he's referring to what is an option, at least on my rhino,  in the chinese market it must common to have the tractors pulling air brake equipped trailers, and apparently he ended up with the air system on his machine, if his tractor's similar to mine it has  standard mechanically actuated disc or drum brakes.. Now i'm a little envious- actually considered trying to order the parts to add the factory style air system to mine…run air tools ,air up tires . Or did i misinterpret the Foton?

I think you are right on this. The DF’s have the same option and have seen some with it. I would love to add this as well for the reasons you mention if I could find the parts.

Heres an except from the manual if it helps at all. A few pics I found as well

Good luck  Dave

5.10 Adjustment of Air Brake Facilities (Optional)

Air brake facilities should be adjusted in two aspects as follows:

a. Adjustment of air pump: If the air pressure is found too low while the air pump is working, the exhaust valves’ sealing should be checked up. Clean or grind the exhaust valve if necessary. If the oil gathering in the air tank is found more than 15 ml after the air pump works for 24 hours, then wear-and tear of piston rings should be checked up, replace them if necessary.

b. Adjustment of air braking timing

If the timing of air brake is not correct, then it should be adjusted. If the pull rod of brake valve is shortened, the brake timing becomes earlier, conversely, the brake timing is put off. Usually, trailer’s braking should be initiated a little bit earlier than the tractor’s shoe brakes do.
