Case international 5130

[Jimquinn]

I have a case 5130 and I would bleed the braking system, fill the reservoir with brake fluid and they would work fine but after 3 days or so they would go again and all the reservoir was empty. I removed the cab and trumpet housings to check the condition of the discs and pistons and see if the fluid was leaking from there but everything was in perfect order.
does anyone know what else it could be, master cylinders?
also to mention the pump the brake lines come from have a knocking sound but stops when I turn the steering. Not sure if this could have anything to do with it.

Take the outlet hose off the brake reservoir. There's a metal pipe insert that governs the level in there and it slides down over time and the pot empties. Push it back up and crank the jubilee clip up. Same symptoms as ours anyway and it's a free fix if it's that

I assume you've put new o-rings into the pistons when your in there? Id also be checking the little steel insert in the resevoir as mentioned above.

Thank you I’ll have a look

If it's like this it's the middle hose. Hydraulic oil comes in from the side one and back out the middle so it's always kept up

How have you put brake fluid in a contained system
The reservoir fill from the steering return
If you somehow put dot 4 in you got a problem
