BTW Monkey you are wrong about disc brakes as well. Almost all brake pads drag on the rotors when at rest(brakes not applied)wether floating or fixed. The term floating does not affect how the pads rest. Some pads have clips that mount on the back of the pads to keep them from dragging. But very few utilize this design.


Some enterprising aftermarket company tried to cash in on this flaw by copying the OE design I mentioned earlier, for use on all brake systems:

Ok son. But youre still wrong. Rotors dont warp. Period.

 

Hahahahahaahahahahahahahahahahahhahahahhaah lol lmaoaa!!!!
Your a smog tech bro. Take your head outta your ***.

 

I find it very very funny how you only post reply's to the simplest problems.
Either tourque wrenches or brake jobs. Hmmmm that tells me something. Hack certified with a huge school loan debt.

 

Actually, I am 15 year practicing technician. Been a Master Tech for the last 8 years and a smog tech for the last 7.
I went through the Honda PACT program. I have zero debt. I answer questions that dont involve any type of swapped motor, because there are too many variables that I cannot see from the internet. I dont know very much about aftermarket boosted applications, so I dont answer many of those questions either. I would be more than willing to fix the vehicles in person however. And if I dont know the answer, then I dont answer. Its better than pretending, like you and many others do.....

 

Hmmm 15 years huh. You would think a master tech would know his way around a CIVIC by now.

 

Like the back of my hand. But I have seen so many f u c k e d up Micky Mouse, back yard swaps done that I know any thing is possible when it comes to swapped vehicles. I wont bother trying to guess. If I can get my hands on the car, I can fix it. Guranteed.



But I digress,this is not about me. I presented the facts,backed up by no fewer than 3 reputable sources. It is what it is, if y'all choose to learn great,if not, your choice. This issue has been discussed on Honda Tech years ago. Search the archives of the suspension and brake forum.....

 

Says the man that thinks he's in a league of doctors and lawyers.

 

I own a 2004 Honda fit and is having vibrations synonymous to yours (between 60 & 80 kilo). I've done high speed balancing and rim straightening on all the wheels. I have also changed 2of the 3 motor mounts. I have changed and skimmed my disc rotors however the issue still exists.

I was told it may be the inner CV joints
that's where I'm at now. I'll be getting the CV joints checked soon. Let's exchange ideas when this issue is resolved. Peace

 

As a response to the OP, the braking system would not cause that kind of vibration. Jack up the vehicle, and jerk the wheels around, if one of the wheels moves more then the others, that is a hint to what is wrong (a bearing or something). If that does not help, then I would get my alignment checked. A tire can skip on the road and cause viberation, or a cv joint may have to be replaced. The brake pad would push the piston in and out, causing the brake fluid to go in and out of the master cylinder, possibly pushing on the brake pedal a little as you are going down the road. If you want to test to see if your brakes are warped, go down the road, faster is better (don't break any laws), and apply a slight pressure to the brake pedal, if you feel it move underneath your foot, a rotor is WARPED. Rotors can easily be warped if it is wet outside. Braking, getting it hot, then splashing water on it will cause uneven cooling, and warping the crap out of it.

 

DON'T U GET HATE IT WHEN U GET PEOPLE WHO HOP ON FORUMS ASKING FOR HELP THE. GET THE PROBLEM FIXED AND BAIL WITH OUT SAYING ANYTHING?? It makes U wonder if you helped them or not.

 

Haha, yeah.

 

DCFIVER rotors do warp on the street, on the track, with grandma riding the brakes, etc.
OP... A stuck brake caliper can drag on the rotor causing it to get hot, warp, and vibrate at highway speed. Just another thought for you.

 

balance those tires!!!!!!

 

This post is really interesting. I'm not Into brakes but would like to learn. I'm all a out engine performance,electrical smog and little knick nacks.

After reading this I did a little research and rotors do not warpe.
I been working with many old school guys and they always use the word warpe.
They would tell the customer if your brakes are pulsating while braking at high speeds we recommend cutting your rotors.
I read if you cut your rotors the problem will return so its better to replace your rotors.
I AM CONFUSED!! Who is right??

Are they saying rotors get cut only to have a smoother surface for braking??
I want to learn and I want a real answer. No bullshit. Please speak up before I make my self look like an idiot like before telling my customers "I recommend cuttin your rotors because your rotors are warped. "Lol

 

No. They dont. It is a common misconception, you are forgiven...

 

Old school guys perpetrated the misconception,because it was their belief that the rotors were indeed warped. Who was to say different? That falsehood has been dubunked for years now. The interweb, and all the wanna be mechanics can be slow to learn though. There are many, many articles on the web that will described what a "warped rotor really is" And for a final nail in the coffin, there are also many White Papers done on the subject by OEMs available for purchase on SAE.org(Society of Automitve Engineers) It is TV(Thickness variation) caused by uneven pad transfer. Plain and simple. I'll concede it is possible for metal to distort and change shape, but it is so unlikely to occur on a street driven vehicle, as to be negligble:

Resurfacing the rotors will remove the pad deposits and return the rotor face to a smooth even surface.

 

Ok. Say I came to you as a customer and told you my brake pads are fine and it started pulsating two days ago at high speed when brakes applied. What would you recommend or say??

1. I had experience when we just switched the pads and it will still pulsate.
2. Also at time we cut the rotors and changed ThE pads and it will pulsate on the next oil change. Cutting rotors is just a temporary fix but many mechanic shop these days are going in that direction .
I guess we learn something new everyday.

 

I got it now. Common problem people say warpe,but they are suppose to say dtv. It's the disc thickness variation causing pulsating because of cheap parts taking abuse or improper installation not cleaning hub area before installing the disc etc.

A WARPED DISC SHOULD ALWAYS BE REPLACED AND NOT BE CUT.
WARPED DISC CAN BE WARPED BY IMPROPER WHEEL LUGNUT INSTALLATION OR CHEAP PARTS SOME TIMES OR MIS ALIGN IF SOMETHING IS OFF.

Many mechanics would say your cars pulsating because you have warpe disc, I recommend cutting them . WRONG!!

 

Sat. morning 94

 

Let me guess, you think all oil,coolant, and trans fluids are thae same as well dont you? You still do parasitic draw testing with a test light right? Ignorance like yours is what spread the" rotors warp" falsehood. These guys frequenting this forum can be forgiven for not knowing the reality, because most, if not all of them ,are DIY'er. But you claim to be a professional, yet continue to stick to antiquated beliefs despite the training and information that is available to us, and not available to them. You are the type of "mechanic" that make our industry look bad...

 

Actually, that would be you.

 

You just love to hate on me because I constantly s h i t all over the false info you post up. LMAO! Go away,youre worthless here son....

 

Not really. You never seem to post in any thread that has the need for any real tech information and I've never seen you demonstrate any of your so called expertise. Any thread with any real difficulty to it and you're nowhere to be found. Ever. When you do post all I've ever seen you do is post up other people research in attempt to make yourself look more intelligent and knowledgeable than you are in order to make others look stupid-failing at it miserably. You choose instead to attack instead of educate. You have miserable customer service skills as demonstrated by your self-important overblown ego that has you comparing yourself to the likes of doctors and lawyers. Your customers must be extremely put off having to deal with you for any length of time. Lord help anyone that actually listens to anything you say on this forum.

Just like this thread. It was all semantics and word play but the end result was the same. Vibration because of rotors-replace them. Especially since they aren't that expensive. Warped rotors are not a myth, they are a misnomer.

 

I don't feel like reading all the crap, but did you try rotating the tires yet? Put the vibrating wheel in the back and see what happens.
