does anyone know where i can get replacment two piece rotors but not as expensive as say from classic industries somewhere like autozone type place ? thanks, joe
i'm pretty sure all the replacements are a 1 piece hubbed rotor, including from classic. i could be wrong. if you end up ordering from them, i would get a 'for sure' answer beforehand.
the pontiac manual specifies that replacements are 1 piece. OE used two piece on 67-69, but the 4 piston brakes require a smaller hub design. there are less expensive ones than what classic sells. they are definitely a 1 piece design though.
You need to be careful when ordering these. NPD lists them for about half but they are actually '69 rotors. Make sure you can inspect before purchase or return the rotors if you're not sure. I just bought the one piece from Classic. Everyone lists them for about $110 to $130 ea. My local NAPA had them for $80 ea but I didn't want to go through another buy and return so I didn't pursue it.
so what you guys are saying isthat i dont need the two piece rotor with my original 4 piston brakes that they only sell one piece replacements so i use the one piece rotors along with my hub and i am set to go??????????
the 1 piece replaces the hub and the rotor. it is a 1 piece hub/rotor. you can use your old bearings, or get new ones. the new rotor will come with new races and wheelstuds. you will need to buy new seals.
the '69 rotor wont work for you because the hub is too large of a diameter and will hit your caliper casting, so make sure you get one that is specific for 67-68 4 piston applications.
keep your old hubs and rotors, or give/sell them to someone who wants them after you have the new parts installed. i am not sure how show cars are judged on whether they still have the 2-piece design on them. i have seen NOS replacements for the 2 piece on ebay before, but they went for a lot, and i dont know if they were real. (replacements as in just the rotor-no hub. leaving it a 2 piece.)
There is a demand for original two-piece rotors, even if they need to go under spec to be cleaned up. Yes, some classes look for original style rotors and judge accordingly.
The one piece rotors are as Scott described. The bearings and seals were used in many applications up through the late 70s and are widely available. Just make sure that you are getting the smaller hub version. I've come to learn the hard way that many of the big parts houses don't know what they are selling.
Ames has been the most knowledgeable in my experience.
