have a problem with my brakes also, have changed the o ring in the pistons on both sides in the back. before this only right side could work for some hours when bleed. No I dont get any pressure on either of the pedals, have tried everything in the pdf listes above, with no result. have tried the clear plastic hose with oil where the break pipes go onto the axel, stood all day and night, was not emty..tried to blow with my breath into the same hose, feels like it is no leak.
so what can be the problem on this tractor then?
