    Question magnum rotors

    I bought a set of Magnum cross drilled rotors for the front of my 88 Lx. installing them was easy and they worked fine for 40 miles or so ,but now i feel a bit of pulsating !
    what did i do wrong ?
    what is the break-in procedure ?
    i looked on thier website but no help there,plus no instructions with rotors.
    new pads also !

    Magnum is chinese crap. They sell it out of canada because most of their products wont pass US DOT standards. There is also the lawsuit avoidance thing...

    Re: magnum rotors

    The rotor is probably warped, lack of ability to tolerate heat. Replace it, or live wit it. It happened to me with a set of Discount Advance Auto rotors except mine were under warranty and swapped them out.

    Yeah, you really have to be careful about what parts you are going to buy and where from. China is importing alot and as said earlier ebay is their back door into the USA.

    I just put some NAPA premium blanks on one of my cars. Fantastic rotors for cheap! Around $35/each!

    Re: magnum rotors

    brembo or nothing is my policy with rotors, pbr for pads... never had a single problem, have cross drilled and slotted fronts with pbr semi metallics, and blanks with pbr's on the rear. paid a wopping 150 for all four rotors and pads.

    I'd go that way except that I get hounded by the animal activist for forcing the squirrel under the hood to work harder than he is now to need that much stopping power.

    To me, North Carolina is more centrally located than Oklahoma, but OK is more midwest than anything. NC is in the original south.

    Re: magnum rotors

    well i'm not from NC, but i'd say the south to me is like alabama, georgia, sc, etc...

    Raleigh doesn't really seem like the south but where i work here in Albemarle, and where i live in Wingate/Monroe, it's definitely the south.

    yeah, most of that PBR stuff isnt to bad eh.
    used to use alot of there mc's and caliper rebuild kits in the garage i used to work at.
    bendix make a real good semi metalic pad as well, i think they are called metal king. until these fancy new pads came out, they were the standard performance pad

    Professional Bull Riding? zZzZzzZZzzZZzZ....

    I'm pretty hooked on my Carbotech AX6 pads. So... much... bite!! But they better for $125/axle. Take a sec to warm up though. Gonna get a set for my Accord when she's back on the road.

    Re: magnum rotors

    Maybe the drilling process warped them. I imagine that drilling through them improperly can generate quite a bit of heat... Starting with cheap, thin blanks, then drilling holes in them probably doesn't do them any good.

    My drilled Brembo OEM rotors on my Accord would boil the fluid just as fast as my old rotors. So I don't really think that holes drilled into any OEM rotors does jack shit to help heat. I think it's more bling than anything (though they do look pretty sweet!).

    when i changed out my rotors i went with napa 5.1 dot fluid...its about 18 bucks a liter but its worth it....i never had fade...only thing is that i started to warp them....i cut them up once and now i just ditched the 10 inch rotor and im going with a 11 inch
