Let's look at the root cause of your brake issue.Don't you think it's odd that just one pad wears out ? You should. <G> The tractor is trying to tell you something.A complete brake service is needed. And you MUST remove the disc in order to do that.So, get your favorite penetrating oil and propane torch out, and spend some quality time with your ET.
Not really odd; the pad on the inside of the brake is smaller than the one on the outside. It's fixed to the brake frame, so as both pads wear down it hits the level where it's eclipsed by the brake frame sooner. Then the tractor is stopping on one puck and the Al frame.
Lift your ET with an adequate jack.Support your ET with suitable jackstands. You will need to at the very least remove the axle tube to tractor frame bolts on the driver's side to give you enough room to work effectively.You may also have to LOOSEN the same bolts on the passenger's side.Remove the caliper from the transaxle. Clean and inspect it carefully. If the casting is cracked
*nod* Done that, bit of a pain. If one happens to have the tiller bar you have to at least remove the outside stays to get at the bolts.
around either the apply pin holes or the stud, discard it and obtain a replacement.
This one was ok actually.
The heat and / or penetrating oil will be needed to loosen and remove the brake rotor that is frozen to the transaxle brake shaft.Patience and caution are the two operative terms for this procedure. After removal, clean and lubricate the rotor hub, brake shaft and woodruff key.Use a water resistant grease of your choosing. I'm partial to silicone grease used for automotive brake work myself.
That's the question: Is the rotor supposed to float on the axle? The old generation brakes have the brake assembly mounted to the tractor using two floating bushings secured by bolts. Thus when you hit the brakes the caliper moves, not the brake disc. Kind of like how car disc brakes work.
This should get you started. Any questions ?
How do the second generation brakes work? Does the rotor float, or do the pads?
