Case 1070 brakes

Still working on my case 1070. Use it to bale hay. Works great with lots of power. Power shift was recently overhauled and the hydraulic pump on the rear is new. Everything works great except for the brakes. All of the parts are there and I believe set up appropriately. My problem is when I push the brakes I feel I have to push it harder than needs to work and the brake pedals pulsate at time. Not all the time but most of the time. It will stop and hold but My leg gets tired from applying so much pressure. Someone on here said it should have great brakes. I do have the hydraulic brake system. Everything else works appropriately. Any thoughts. Thanks
 
(quoted from post at 10:58:10 07/14/16) Will they work OK if you you just one brake? Rod.

I separated the brake pedals and tested them last night. Seems to work a lot better. Each pedal when separate is easier to push, grabs and holds quicker, and the pedal does not pulsate. The only difference is when I push the pedal on either side I hear a squealing sound like a relief valve or something. Any thoughts as why the work well when independent but not together and what the squealing sound may be. Thanks.
 
I am familiar with the annoying squeal on my early 1070 , it has power brakes , I think the squeal is the nature of the beast ,, I hope some of the Case Gurus will chime in and teach us a few things about case brakes , my left brake is not much but the rite brake skids ,..
 
My 770 acts like this when the brakes are way out of adjustment.

Try tightening the adjusting nut on top of each brake a couple turns.


I'd bet your parking brake doesn't do much either?
 
The squealing sound is the relief valve, should make the sound only when the brakes are firmly engaged. Your pulsating when both brakes are applied is a
rather common complaint on 7-1070 tractors. A kit was available at one time to remedy the condition. Some tractors did it and others not. I have a 8 and
970, both do it. Having good brakes disc's and everything adjusted properly does help, but will not eliminate it entirely. I simply have learned to use
one brake carefully, when I need both I really have to stand on them.
 
First, measure the adjuster, if there is much more than 1/2" threads protruded, the adjuster is too far out, swap shims if not alreadydone and re adjust and re check. Now, if shims are already outside, liners need changed. Have you bled the system? can cause issues. Are both springs intact on both sides for the return? You might need someone to stomp the pedal and watch the slave cylinder. If one moves more than the other, adjust so that both are same. Good luck.
