3340 brake access need help ASAP

I think I have fluid on my 3340's brakes. I have good pedal but it won't stop no matter how hard you press on them. How do I get access to the brakes to be able to clean them with some brake cleaner to see if that will help. Thanks, justin

Take of the rear weel, then remove the rear portal. If you have oil on the brakes you need to adress that problem when the portal is down. Have you identified which side? I think your breakes is the dry disctype and if so do you have the same problem with the handbrake. You can se the slave cylinders from the back of the tractor. Do they move when you push the pedal?
