well i here a sound like metal grinding metal after every revolution of the tire, im pretty damn sure its a rotor, those things are pricy anybody know where i can get one cheap for a 1990 300zx N/A

this is a great deal, wish i would of found it when i was buying new rotors. for $450, you get front AND rear slotted/drilled rotors, front AND rear pads, stainless steel brake lines, and brake fluid. if we buy all that stuff seperate, it would be about $650-$700. here is the link, http://conceptzperformance.com/Cart/description.php?II=309&Car_Type=300&UID=2004112023102569.76.137.188

dude...you dont even have to worry about it. metal on metal isnt your rotor. its your brake pads. if you drive to long with the metal sound then you might need a new rotor but i doubt it. go to auto-zone, $20 for new brake pads for the front. if you need the back, it wil probably be a little cheaper than the $20. (i have bigger pads on my bicycle than i do the back of me Z). :lol:

after that, your gonna need some brake lube and some of that "no squeak" stuff. total, i spent like $23 for the front brake pads.

then beings your hearing metal on metal. take some medium course sand paper and sand down the rough part of the rotor. you should be able to tell by rubbing your fingers across it. if you need help installing them just PM me or ask away. i just installed all 4 on my 90' a couple weeks ago. good luck...

well i also believe its the rotor because the car wobbles from side to side, but i also need a new rim because one is fractured

wobbles from side to side?...thats more than a rotor, :lol: you mean the steering wheel shakes when braking??? yeah, you may need new rotors then, but the metal to metal sound just means you need new brake pads. that brake set that freak gave you is a great deal...but if you look on ebay you can get it even cheaper than that. good luck...

but on ebay, they probably aren't as good quality, therefore they could crack or something. you get what you pay for. where is your wheel fractured at?

maybe they are, maybe they arent. they are only like $50 cheaper so who knows.

Napa you can get cheap OEM replacement rotors, for about 60-100 bucks I cant remember I just did mine about 45 days ago.

all 4 or just 1??? if thats all 4, just take them 2 a machine shop and have them machine you some slotted rotors, s***.

Just the front 2 rotors and pads with shims. And one retaining spring........ damn pot holes.

yeah i think i got a bend on the inside of one of my wheels from a pothole. im thinking about taking it up with the city.

but still thats not bad...so without pads. probably $50-70. i might have to look into that, machine shops can make slotted rotors right. im just assuming that is basically how they make slotted rotors, right?

they can but buy a quality brand rotor first, other wise they may crack or warp.

i see...i will probably just end purchasing a full-kit from CZP when ig et around to it.

That would be wisest..... I am still up in the air about my brakes.... dont know yet, might go with a UK firm or stay asian/domestic.

how hard you think it would be to custom make your own big brake kit??? i always thought about it. like seriously the only hard part would be getting the caliper remounted, right? im not saying that i can do this with a standard hammer and sockets but im sure it could be done, of you went to the drawing board and designed a new bracket and then go to the metal shopa nd buy yourself a hunk of iron and take it to a machine shop and have them make your blueprint come to life. ehh...maybe im just dreaming. probably end up costing just as much as Z1's big brake kit, anyways. but it would be pretty cool to say i designed my own big brake kit. :D

I also think you have to think about metalurgy, the type of metal the rotor is made out of is important to, It needs to disapate heat. And resist warpage.

if you had access to a cnc machine and some good steel i'm sure it could be done... for the rotors at least.. the calipers could be a different story however

well...i didnt plan to build new rotors from scratch or rotors. hell you can take calipers off random cars that have a more powerful caliper. and customize a bracket so they will mount to your rotor.

according to z1, the stock calipers can provide enough clamping power to do a big brake kit. hence they rebuild the stock calipers with bigger rotors.

its all just an idea, personally i would just rather buy a big brake kit from z1 or another company and call it a day.

that is what i love about auto tech class. we have access to all different kinds of machines. i can balance my tires for free, i can do an alignment on my car for free, i can grind down my brakes for free, ect. plus, we have four lifts, makes it a whole lot easier to work on your car. now only to let my school let me use the shop whenever i want.

yea UTI had the same policy you can work on your car during the certain Weekends but otherwise you had to try and slide it in during shop time. Good thing is that they had all the tools you will need too. Then when I went to Volvo it was even better, we just had to be done with our labs then we could do whatever short of engine swaps on our car.
