    Real talk? Brake Job/Rotors

    Ok, I take one of the girls cars(Civic 07 Ex) for a brake job, left too long, they tell me it needs

    new or machined rotors. I say WAT? The guy tells me machined is ok if all goes according to plan

    but there's a 50/50 chance the end result will be a noticeable vibration compared to new rotors.

    I choose the less expensive option because I've never heard of such a line and because I'm cheap.

    Cut to today where I use "the car" to travel down island and fuck if I don't notice a telescoping type

    vibration at certain speeds, even on perfectly smooth highway pavement.

    Any one have experience with this? Is it my imagination? Should I pay to have

    new rotors put in?

    What's a rotor?

    no what the problem is is that whoever turned (machined) the rotors didnt have the rotor chucked up correctly in the brake lathe AND OR.. this could be from a loose wheel, out of round tire, improper ait psi,. the one thing to remember is this ALL brake rotors have a minimum thickness that you can cut too if your rotors are to that point then you have to get new ones. Being a A.S.E. certified technition i am willing to bet that all they have to to is turn (machine) the rotors again... Hope this helps

    thanks, being an 07 with few miles I wondered whether new rotors were necessary. It's probably my obsessive mind that has me concentrating on the ride. The tires are new but I was also thinking

    balance. The experience comes at 90 to 98 km/hr or there abouts.

    A rotor is what mounts just behind your wheel, you have a brake pad on either side of your rotor that is held on with what is called a calaper when the brakes are aplied the hydrolic pressure pushes a piston in the calaper which squezes the pads together.( pitchur this a cd disk on a pencil a finger on each side of the cd now spin the cd and close your fingures on the cd the cd stops).... Now the vibration(pulsating) that you feel is 99 times out of 100 a rotor that is not true (meaning having a flat surface)> What causes rotors to warp is a number of things. under a 35 mph to a dead stop in normal conditions a brake rotor can reach teapratures up to if not exceeding 900 degrees and if you hit a water puddle with a brake rotor that is that hot its gonna warp. The car that is my avatar runs 8.40 in a 1/4 mile at 163 mph and is street leagal i check my brake temps after every pass my front brakes rotors usually see teps of 1950 to 2300 deg i replace my rotors about once every 2 months.... Sorry for the fucked up spelling and i hope this helps

    You should have just bought new rotors. New rotors for a Civic are not that expensive.

    it all depends on driving habits 70 to 80% of all stoping is done with the front of the vehicle if you "ride" your brakes (meanning leave your foot on the brake pedal while driving) people do it unconchesly thay is constantly building heat in that rotor and pads for that mater and will cause premature falure. my truck is a 06 1 ton deisel with 300 k miles on it and its jus now ready for front brakes but i use the gears alot to slow down( i must add it is a standard transmition).

    so you're saying there's a decent chance having the rotors machined would or could cause this roughness/vibration.......

    the steering wheel doesn't shimmy or anything, it's just not as smooth as

    I would expect.

    that's it, I'm going for new rotors.

    I know, the difference was not much, I'm a cheap fuck and I thought I was getting a line from the technician.

    Buy new rotors you cheap bastard. They are pathetically simple to install, you remove your wheels and see the big shiny silver disks? Those are your rotors. The brake pads clamp down on them, and save your life (more or less).

    Only a few things on a car I am never cheap about, and by far brakes are at the top of the list. Always buy new rotors when yours wear down, machining them is asking for trouble you do not want, especially in your hostile climate.

    I'd be happy to guide you through the removal process, about the hardest thing you will have to do is bleed your brake lines, but come on, I was doing this shit for my friends when I was 14 and couldn't even drive yet. It's one of the simplest do it yourself repairs you can possibly do.

    True new rotors could be cheaper than turning them...

    But they also could be warped from the get go...

    Most mechanics would measure them first, turn them if possible, but turn them "on car" with special lathe...

    Front wheel drive cars should be done "on car"...

    This I know as I worked on cars for over 40 years professionly...

    This rings true with me.......My specialty, so to speak, means that joe average knows nothing about what I'm preachin, yet the last thing

    I will do is lie to a client, regardless...so in a way I'm a sucker to those who will......whatever

    just seemed like a fucking lie to me and now I don't know what to think.
