It is for a 15X6.00-6 tire. I think it was MATCO but not s ure. One of my bearing race is turning on mine and I have some wear on the axle so I may want to replace it. > > THANKS! > ________________________________ Message 2 _____________________________________ Time: 06:49:23 AM PST US From: "Bill Schertz" Subject: Re: KIS-List: TR-4 Main Landing Gear Wheel Assembly The replacement rotor was tool steel, and they had different pads too, I suggest calling them directly.

The peddles need to be about 2" longer. Measure the hydraulic pressure at the calipers with your normal foot pressure, it will probably be 250-350 lbs. and it needs to be much higher. The low pressure generates allot of heat and poor breaking. Call Matco, they will tell you the pressure you need to see.
