Reply to "New guy looking"

Joules, I can't indent them other than to say that they conform to the service manual.
No vented discs. Very heavy cast iron calipers with four pistons up front and two in the rear.
The linings are made by Textar with the right front having a electric wear sensor. The wire going under the pad broke off upon removal and the P/N V14316FF goes nowhere. Other than that they look stock. Very frustrating but I was hoping one of you guys would Know the make , model and P/N.
Get this, I don't think the brakes have ever come apart and been inspected. All linings look good with almost all wear on the rears.
That doesn't seem right to me.
The pistons are so frozen into the calipers that it took hours of soaking with Mouse Milk and heat to free the right rear. Right front is soaking.
It would really help if someone had info on the sensor. Service manual has no mention of it. I wish I knew who made the system then I could get some where. I'm afraid when I get the front caliper apart it may be destroyed with piston corrosion explaining why it wont come apart.The back cleaned up real well. Inop is hard on machines unless preserved.
