Hi all, Hope I have the right board for this question. I have a j.d. 970 and have been hearing some noise from my brakes. How expensive are parts for this model and how much of a job is it? Thanks :)

I believe the 970 has dry drum brakes.
Very easy to work on. The cost of the shoes may be the hard to take part. The price of the shoes for my JD 850 were over $50 per shoe (X 4 shoes) if I remember correctly.
The 970 may be similar.. ....

Actually the 870,970,and 1070 switched to wet disk brakes. Normally these brakes can be expected to last a very long time. I don't recall ever replacing any since 70 series came out. I would suspect contaminated transmission fluid or improper type of fluid. Wet brakes(and clutches) require fluid that has friction modifiers built in for smooth operation of clutches and brakes. I would recommend changing the fluid and filter. While you are at it, remove the sump screen and see if there is any brake lining material on the screen. If the fluid is contaminated with water or other incorrect fluids, you may need to change the fluid twice to get rid of all contaminants. If you do happen to find brake material on the screen, the final drives need to be removed to access the brakes. There are three brake disks per side and the disks cost around $75 - 80 each. ther are also separator plates that may need replacing at around $40 each. Good luck! ....

My mistake on the dry brakes.
Thank you for the information.
I was thinking the 50 series, 70 series and 90 series were all dry brakes ....

The IH mechanic down the road once told me that Case makes the best Hydro fluid on the market except if you own a Deere.

Apparently the friction modifiers are not compatible with Deere brake materials.

Bottom line...... use Deere fluids if you can. ....

My 870 requires lo-vis Deere fluid. I used the regular Deere fluid once and had problems with slow hydraulics and gear shifting problems. Might want to check to see if the 970 requires lo-vis fluid. ....
