brake chatter is usually an oil related issue:
one of the first special qualities of jd's(and others)special oil is reducing brake chatter yet not impairing braking abilities. as far as i know cih hytran oil have similar qualities as th jd hy-guard oil.but mayby it is "contminated" with "regular" oil from shring implments with other tractors or any other way. the chatter can speed up failure of brake linnings .
i sggest you check yor brake linings and fill the system wit fresh oil(make shure it meets jd standards) andtry to remove as much as possible old oil when emptiing the system.
the brake accumolator is there to give you brke pressure for emergency braking when the engine dies on the go(emergency braking) it is locaed below the dashboard.to check it turn off the engineand then depress the brake pedald , they shuld feel solid and not go all the way to thefloor fo several9i do'nt remember how many)brake applications.if notit should be checked and replaced or recharged with dry nitrogen only by a jd dealer shop.(it may all be written in the tractor's opretor manual).it have nothing to do with the brake chatter. david
