2 Set Brake Pad Kit GY21943B GX20494 GX20515 GX23240 for J-ohn Deere 42″ L, D, X Series 100 105 115 100 110 120 125 130 Tractors & Lawn Mower – with Retainer & Torsion Spring

I kept tossing the deck belt after disengaging the PTO, tracked it down to the brake not slowing down the pulleys on the spindles , with the blades spinning freely, the momentum tosses the disengaged belt.Got to tell you, this was probably the hardest part to replace on the entire mower. I rebuilt the deck 2x, replaced the transmission, dozens of blades, belts, springs, pulleys … but by far the brake kit, I never want to do again.Do the “easy side” first, the one without the engagement bracket, this will give you a feel for the 2nd one.Put gloves on as you have to compress the spring on top of the brake “L” bracket with a special bottom washer retainer inside that whilst putting a top retaining washer on and feeding the bolt in. That entire assembly also has to be clocked at a required position.The 2nd one it the same, but it must be done in a fixed position as the “Dog Leg” bracket is attached via a rod to this assembly.Once you get everything back together adjust your brakes with the deck free from the tractor. You have to adjust both sides , its 10mm, I had to bend the cranky side “L” bracket , did so by removing the pully and helping it with a hammer.Another thing, it comes with 2 new springs, I only had one, so I replaced one, that new tension changed my primary PTO leaver, my deck belt was too tight, so I had to re adjust the 2 adjustment bolts that hold the PTO cable.Im happy it’s not tossing the belt anymore, but in retrospect, I wonder if just tapping in my old ones would have worked.
