    john deere 690 E LC comments

    Cat 950G

    i agree with lee, check the brake pilot pump, may be the seals or the vanes have worn out, and before dismantlling look for the brake accumulators. you can do that by installing a 3000 psi gauge in the testing port of them, turning off the machine and hitting the brakes 5 or 7 times, you will...
