Front Brake Pulsating - Bobbin Cleaning - Fixed!
A big Texas "tip of the hat" to this Forum! My '08 w/19,500 miles began exhibiting a pulsating feel when I softly used the front brake. She didn't have it when I put her up for the winter about 4 months ago so I was surprised when she gave me that uncomfortable feeling.
I searched this Forum for "brake pulsating" and there it was. A recommendation for addressing this issue. Clean and ever so slightly lube the bobbins. Heck, I didn't even know I had bobbins till I read the post!
They were very, very tight (evidence by 2 busted knuckles and a pinched palm.) Even after a couple attempts and allowing time for the slight oil to take effect, they were still very tight.
This morning, I hit the Forum again and dug a little deeper. 2 Youtube videos were there showing a method using a bolt and nut to more easily turn the bobbin. Back to the garage I went. This method made it much easier to turn the bobbins, spray with brake cleaner then carefully give a small squirt of WD. I wiped everything down one last time with brake cleaner and headed out.
Pulsing gone!!!! I read that many were only able to solve this issue by replacing their rotors. I'm happy to report for my little girl, this seems to have done the trick. If I have to add this to my annual maintenance list, so be it. It's not that difficult.
Thanks forum contributors!
