Hi,
I own a 1989 MKI MR2 and my left rear brake disk needs to be replaced because of a small scrape on the face of the disk. It makes a little noise as the pads rub over it, plus it has a little tweak to the trueness of the disk which I can feel in a slight pulsating as I come to a stop.
Anyway, I located another MKI in a wrecking yard and grabbed the left rear disk, among many other parts that I always grab for possible issues in the future
.
When I got home, I removed the left rear wheel and held the wrecking yard disk up to mine and was surprised to see that the wrecking yard disk diameter was a bit larger then mine
. This disk did not appear to be an aftermarket update of any kind.
What my question is...did Toyota make changes in the rear disk size in the middle of the production of 1989 MKI MR2's? The wrecking yard listed the MR2 as a 1989 just like mine, though it did have more options like power windows, cruise control, etc. I researched online and it appears that the MKI MR2's came with a 9.4 inch diameter disk. I have looked for rear disk replacements in many Toyota parts web sites and almost everyone I have found are listed as 10.5 inch disk.
WTF is going on here? Will these larger disk work on my car without having to replace the calipers? Sure didn't look like they would. I sure would like to put these slightly larger disk on my car. Now if the wrecking yard happen to make a slight mistake posting the year of this MR2, why would Toyota down sized their rear disk from a prior year.
Any help is appreciated...Thanks
