Here's Your Rear Disk Brake Lesson for the Day

[sjaroslo]

If you're having a somewhat difficult time getting your rear calipers mounted, and then once there, find that there's absolutely no way that your pads are going to fit, you might want to check to see if the formerly high-end shop that got your car into "roller" status might have inadvertently installed FRONT DISK ROTORS (1.25" thick) instead of REAR DISK ROTORS (1.10" thick). Just sayin'.

Sigh. If there's something stupid that can happen to a build, you guys can count on me to ferret them out. It's what I do.

My wallet is writhing but I'm pretty happy otherwise. This is what brand new stuff is supposed to look like! And this is what a rear rotor is supposed to look like.... I'm going to learn a lot more than I thought I would on this build, let me tell you.
Would you rather have this?

1.10" thick never looked so good

I know it was the wrong rotor but did you really have to put it through a wood chipper? LOL

Everything went together quite nicely once all of the correct parts were on hand.... Needed to have the rotor hats drilled out to fit the base of the studs (https://www.pro-touring.com/showthre...r-Larger-Studs) but otherwise, a nice install.

Why didn't I have the good sense to put a coat of black paint on the face of the axle before I assembled everything with Red Loctite?

Unfortunately it looks like you have the standard Wilwood 7420 pad issue. The pads looks to be sticking up beyond the edge of the rotor by about 1/16". Rest assured its not your bracket, its the pads. For some reason Wilwood adheres the friction material to high on the backing plate. It you get pads from Porterfield or Hawk, you will not have that issue. Probably others as well.

Very interesting, I hadn't really noticed before. I think that the picture makes it look more pronounced than it is but I'll have to go back and take a closer look now...
