Honda OEM brake pads are not great, they overheat and leave deposits on the rotors hence the shimmy feel and vibrating feel when braking at high speeds.
Yep, I read some long term testing on a Honda recently where they replaced rotors a couple of times due to recurring shimmy/shake. Many drivers bring this on themselves when they haul it down hard and then sit on the brakes at a stop. That super heated pad clamped down on the rotor will transfer material and BINGO...
Correct. Here is a great post by Jeff of Temple of VTEC. I am quoting him. When I first got the TSX, I had similar problems, even my friends 2011 CR-V still has the same problem. I also noticed this does not happen often on other car oem pads.
It's Time to Rethink the Brake Pads
One item that has escaped Acura's attention is the TSX's brakes. We're going to be brutally honest: the stock brake pads are pretty bad. The feel is okay, but they provide somewhat weak stopping power and are prone to overheating easily (particularly when slowing from freeway speeds). When they overheat, they tend to leave deposits on the rotors, which can lead to a very noticeable and irritating brake shudder. Many people misdiagnose this problem as rotor warpage, but as we proved on our own car, it's really the stock pads chubbing the rotors. It only took a few thousand miles for this problem to appear on our TSX project car, and these were very gentle miles. While the symptoms felt almost exactly like rotor warpage, we decided to swap out the stock pads for some more aggressive aftermarket pads, and the results were simply astounding. Without any rotor resurfacing, the brake shudder and wobble disappeared almost immediately, and within a few days of normal driving, all of the OEM pad deposits were wiped clean from the rotors. To this day, there has been absolutely no brake shudder and brake fade is a thing of the past. Even more impressively, the car has benefitted from a tremendous improvement in braking power. The only downside to this pad upgrade is that the new pads will squeak in very rare circumstances and they generate appreciably more brake dust than the stock pads. Otherwise they are one of the biggest "bang for the buck" modifications out there for the TSX and we highly recommend it. We installed Axxis Ultimates on our TSX, but similar results are likely with any number of other aftermarket fitments.
