    That's odd...... When I went to the parts store and asked for the rotors ..... that's what I got.... just a brand new pair of rotors. Maybe you need to talk to a different parts guy... :dunno:...

    HEY!!!!
    It has to be a 1990 4X4 1/2 ton PU also not an extracab. This comes as rotors only. then machine the center holes out to the correct diameter. The 2wd is only 5 bolt lugs.

    A guy on EBAY was selling a set already machined last week (done now). I think opening bid was $95.

    I am in the middle of the conversion myself. Check out Bill Jackson's write up in the tech section. Your rotors need to be the fronts from a 1990 ish chevy 1/2 ton, regular cab 4x4. Not heavy duty, they are too wide. You need one's no wider than 1 1/4". I had mine machined to the 4.20" that Bill suggested and it worked fine. If you are using Monte Carlo calipers it took me 2 days and several parts stores to find brake hoses. Raybestos # BH38149 or NAPA 38149 ( had them crossed with Bendix, Wagner and a couple other brands ) and had no luck, unless I want to wait 7 more days to get them. The hoses fit a 82-83 Nissan 200 sx rear. Nissan doesn't have one in the nation. I have a set now but have not installed, if they work and you are interested I can give you the brand and part #. Good Luck!

    Very cool post!
    Questions:
    1) What calipers are these?
    2) What parking brake set up will you run w/ this?

    Thanks!

    I do believe that this is the monte carlo calipers with parking brake, either that or the eldorado ones.. The info posted was from the conversion that Kemper did on the Hornet.

    It's cute that you actually thought that I had original tech info to pass along steve :princess:

    Here is the original thread I got it off of

    Clarification...
    I do not believe these are the calipers with parking brake. I believe he used a stock T-Case FJ40 parking brake.

    Does anyone know of a source for the E-brake hardware for the Monte Carlo/El Dorado rear calipers??? The lever, bracket and spring.

    GM doesn’t carry them anymore, and junk yards here are almost non existent.

    See above about The Streetrod Manufacturing Co. - they supply the whole calipers & might be able to get parts. I assume they scrounge rebuildable ones from "recyclers".

    I got my kit from TSM, with an ebrake cable from Custom Cables in CA. The calipers are from an early 80's Caddy (TSM recommended), and I installed a Wilwood proportioning valve. I'm having a hard time getting the proper power in the back (I can't even lock them up on a dirt road).

    Not to hijack, but should the stock proportioning valve be removed? Right now they're set up as the MC to the stock prop valve to the Wilwood valve. Perhaps the stock valve is shot?
