S-10/ Blazer rear rotors
 

Does anyone have the dimensions on the rear rotors for the late '90's Blazers? I have a set of rotors that were part of a Baer Brakes kit for a full-size truck that they put together. Yeah, I know, two different vehicles, but supposedly this kit was put together with those particular rotors and I want to verify that fact. I used a different kit on my K1500 and I've had this one on the shelf. It's time to sell the parts and I need to identify them. (These were five lug rotors also...)

I took pics of these rotors I have. They are 11 5/8" or 295mm in dia. Thickness is 20mm and the height of the hat is 60mm. Depth of the hat is 54mm. The lug holes were drilled by Baer.

These may also fit '94-'96 Chevrolet Impalas (?).

Disc brakes came out in 98 for the blazer. 97 and earlier were drum.

98-05 2wd rear rotor: 296mm diameter, 20,mm thick, 72.8mm total height(so the hat would be 62.8mm tall)

98-05 4wd rear rotor: 295 mm diameter, 20mm thick, 95.3 mm total height(so the hat would be 75.3 mm tall)

From the measurements you gave, they are close, but not a direct fit for a blazer.




94-96 Impala SS rear rotor: 295mm diameter, 20mm thick, 59.1 total height(so the hat would be 39.1mm)

That's not a direct fit either

Thanks for that info. I think I "ballparked" that height measurement and I need to take that measurement again on a flat surface with my digital caliper.

I think these are Impala rear disk rotors. Total height is approx. 60mm and thickness of the rotor is 20mm (39.1mm + 20mm). That math is close enough for me.
