Here is a new one on me.....Rusted Rotors beyond salvage.
I was getting some pulsating in the right rear brake on the Buick. These are / were the original rotors that were never cut.
The rear rotors were heavily rusted on the innerside. I brought them in to a local shop to be cut. The pads had 30,000 on them and were still okay. Shop # 1 said they were to rusty to cut. Shop # 2 and 3 said the same thing.
Mechanics at Chevy told me to just buy new ones. Said to go with the cheap ones as they only last so long due to the cheap recycled metal being used in todays manufacturing.
One Goodwrench was surprised I got as many miles out of them before the pulsating occurred. He said he replaced all 4 rotors at 50,000 on a 2006 Silverado.
Thank You GM....
PS, the rotors on the Bonneville are 18 years old and are just fine.
