I have been trying to fix the brakes on this 340 int back hoe. the right pedal was froze. finally got it to take some grease and can move the pedal some what freely but it seems to me the tight pedal is to close to the left pedal. when you push down on the left the right trys to go woth it. lock arm is out of the way. I have the cotter key out and the large washer from the left pedal but cant seem to get the left pedal arm to move outward any. I assume it should just slide out. I have the brake assembly off. is there something that would hold the arm in place I'm not seeing. thanks n norm
