I've been chasing front brake squeaks lately. '86 Cutlass needed pads, '92 Bravada would've needed some this summer...changed'em out anyway and '97 Bravada pads were in great shape. Applied brake squeak grease to the contact point on the caliper pistons on all so quiet should return BUT while I was checking things out while I had the wheel off the '97, it occured to me that after all these years, I hadn't checked the front differential lube level on either Bravada, so I put the tire back on, let it off the jack and squeezed under with my trusty 15mm combo wrench and removed the plug. Stuck my little finger in and removed same dry. :22yikes: Tried again and the little rascal was dirty but dry. Took about a pint to get a normal level. Same thing with the '92. I'll check the rears real soon.
