2006 armada brake light on and brakes grinding

[wfuarmada]

The brake light on my armada comes on from time to time. When it does and I depress the pedal the brakes grind. The dealer wants to replace the power brake booster to the tune of $900. The dealer does not seem to want to try the fix outlined in TSB ntb06-040. Has anyone else had this problem and if so what was the fix and how much did it cost?

First off, welcome to NICOclub! Glad to have you join us in the Armada/QX56 Forum.

What is the TSB you noted? If it is the rotor issue, chances are that the rotors are not the problem with what you described. I had the rotor issue on my '04 QX56. Good luck!

Try a different dealer. I simply called some local dealers and got quotes. Seems to range between $105-120. I went to one that charged a bit more as they were the only ones that could do it while I waited. I was there about an hour.

However, the service guys did tell me that if this did not solve the problem, that they would need to replace the ABS module. Given this is a problem with the ABS/VDC system, not sure why the dealer you went to would even suggest replacing the booster. The issue also reappeared for me last week. But that's the only incident so I'm gonna see if it occurs again. At that point I do want to confirm the reprogram was done correctly as the TSB mentions no further instructions if the issue reoccurs.

That sounds like something is up with your ABS. Does it sound like the grinding of the ABS or is a different grinding sound? Or does it feel like the break pedal is being pushed back?
