Probably rust buildup on the rotor surface. Just make sure the pads and pins slide freely.View attachment 82825View attachment 82826
Checked the front brakes on moms car as they were grinding away only when you hit the brake from about 35 or so and higher. Front inner pad on driver side is measuring 5mm the outer pad and pads on the other side are all measuring 6mm. Probably going to try and take the pins off and lubricate them to see if that will fix it maybe there is a hang up somewhere. It only has 27,000 on it. Never had the wheels off besides rotating them. I will double check the back pads but it’s highly unlikely that they would be the issue. Dad said probably will just go ahead and change the front pads and hardware and re-lubricate the pins and see if the issue continues on. I watched several videos on YouTube and all of them appear to replace pads before they make it to the 3mm mark they were replacing about 6mm or so so I’m wondering if there is an issue with these that I am unaware of. Also applied anti seize to the lug studs and wheel mounting surfaces. This car has the two piece lug nuts and only one was swollen luckily. Might order some new lug nuts for all around when we do the tires as I did have to hammer a socket on the swollen one.
Ended up power flushing the block, heater hoses and heater core, as the cooling system was full of brown crud. Got it all flushed out and filled it with Dexcool and water.Currently in the middle of a radiator replacement on a 1999 Tahoe. I've also got a 2016 Nissan Sentra for radiator replacement, but I won't have the new one until Friday.
