Brake Oil Fails

As John Deere runs a single oil supply for the back-end, brakes and transmission it's crucial that discs are changed before they start breaking up and going around the system.

With sensible driving, brakes can last for thousands of hours, but heavy users can cause damage very quickly.

The discs themselves cost 160 USD to 220 USD each and it usually takes about a day to replace them. However, the costs begin to rise if they've been left too long and you need pistons and backing plates.

If the brakes have started to break up, the suction screen in the rear diff housing should be inspected for debris and cleared if necessary.
