Here’s what it looks like with the wheel off. Everything looks normal, but that disc is obviously getting some wear. I have been checking it with a laser-point infra-red pyrometer, and it’s been running quite a bit hotter than the other side of the car.
At speed, after about ten miles I start picking up vibration, sooner on a hot day than a cold day. For a while I thought the tire itself was getting a bulge in it (and I have not ruled that out, but the disc has a tell-tale hot signature to it so I think I have a brake issue).
Here’s what I discovered when I pulled everything out.
<br /> That's NOT RUST on the disc by the way, it's an illusion that showed up on the photo, strange, but actually the disc is uniformly polished.
I popped the plastic covers off the back of the sliding bolts, and removed the sliding bolts. Off came the caliper.
I lifted out the pad, so far everything looks pretty normal.
<br /> (that's not rust on the disc, it's an illusion that showed up on the photograph, I think it's a reflection of the ground, due to the flash going off, pretty strange, but I assure you that disc was polished enough to shave with.)
Upon examination of the pad, I don’t see anything out of the norm.
I decided to pull the rubber seal back on the piston, it looked good. I gave it a shot of Gibbs just to encircle the piston to be sure it was lubed and free of corrosion. The C-clamp pushed the piston in, everything felt good. This will allow reassembly to be easy.
See next post for a continuation (don’t want to load this single thread up too heavily with photos)
