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.

Everything was exactly as described. The parts were perfect and installed fairly easily. After installing, the product worked very well and solved a previous problem. Very happy with the results

Worked great to rebuild my deck on my 42” John Deere LA125 mower.

Perfect fit. Only 4 stars because I don't know how long they will last.

Nice kit

These brake pads are exactly OEM fit and quality. Saved me time and money!

Exact fit for my D110 mower. The kit even included two idler arm springs (GX10120) that weren't shown in the pictures. Used one now and have a spare for the future. Blade brakes are working perfectly again!

My John Deere riding mower blades were spinning when I started the mower and it seemed to drag a little, like it was hard to start but finally did. I looked at the brake arms and the brake pads were completely worn off, no wonder the blades were spinning. Easy to put on, with a little work and viola! Fixed the blades from spinning. Good fix anyone can do.
