I started to feel some shimmy when braking and a softer pedal so I figured that my rotors were warped. At the same time my Dunflops were getting really worn and I'm sure the balance was way off. (Had the 60-70 mph wobble too.)
Yeah, so after reading up on brake pad and rotor combos I decided that Brembo blanks and OEM pads were the way to go. The Brembos I am sure are better than OEM and less than half the cost. However they are hard to find. There was one place online that had them for $100 each, but Tirerack had them much cheaper and on back order. The rep I spoke with said that they might get the rotors in sooner than they list, but to "be on the safe side" they told me a later date (a week later!). Since I knew I still had some pad left I figured I'd order them and just wait. So I got the OEM pads from Partznet in like 2 days. I ordered the rotors on June 12 and the "estimated availability" was July 12th, then it changed to July 30th (on like July 10th)! I called them and asked what was up with that. They said they
were just on back order and they could give me a refund if I wanted. I said no because I want those rotors. Now the availablity is October 1!!!
In the meantime I had some Revos mounted and the brakes felt much better (shimmy-wise) so the tire balance/crappy Dunlops were contributing to the brake shimmy. I could still feel it a little so I still felt good about placing an order for the Brembos.
I ended up buying some cheap Autozone pads and slapping them on there to last me until October. (I want to use the OEM pads with brand new rotors). First thing I noticed was that one caliper piston on each side wasn't extended as far as the others. They were not frozen as I was able to press them back into the caliper using a c-clamp. After reading about frozen caliper pistons and seeing a picture of the uneven pad wear I looked at my old ones. They were wearing unevenly, but not too bad! I am hoping that mine don't freeze up! I figure that I was only applying pressure to the pads using 3 out of 4 pistons which could be the cause of the softer pedal/less braking torque.
Next thing I noticed after a week of driving with them was that they started sqealing when I first braked but went away if I braked harder. I think I may not have used enough grease on the shims/pads/pistons. I'm living with it for now until my Brembos come in and I do them over again. Second thing I noticed was that there is much more brake dust accumulating on my front rims! Damn cheap pads! I can't wait to get the OEMs back on there.
So there's my rant. I will have an update if I ever get the Brembos!
