Brake Shudder

I did a search for brake shudder and I cant find anything that answers exactly what i'm wondering.

My truck has right at 178k miles on the clock.

I put new brakes on it probably 3 weeks ago.
Turned my rotors for the first time ( yes I know 178k on a set of rotors never getting turned is beyond stupid but lol idk)

So now even with the high dollar pads on it i still get a shudder like the brakes are worn out. My rotors looked and felt good once I got them turned but it still shudders.

My thoughts are that the rotors are fawked up or something and that's why its shuddering which seems like the only thing that can make them do this.

The guy at the parts store is tellin me it could be the calipers i mean WTF i really dont think thats true but I know someone on here can help me out with this so lets hear it lol

So I hoping someone will second me on the thought that I need to buy some new rotors for $60 and fix this annoying problem

Thanks

 

rotors might be to thin .not takin the heat away enough.

 

Your rotors are prolly worn unevenly..thats why your getting the shutter! I'd get em resurfaced before you ruin your new pads!!...

 

X2 What he said...

 

Resurfaced as in getting them turned or can they like actually resurface them?

 

Just take em to pepboys or brake masters...they'll resurface them so that their smooth and even... They literally resurface them lol

 

It'll prolly cost somewhere around $30 - $50

 

Quick question,
Did the SHOP "mic" ( measure) the rotors before turning them???
With that kind of mileage ,I would venture they are thin...
I'm being lazy and not going out the garage to get my book..BUT I think 22mm is stock and 20mm is thin...that is how close tolerances can be..
It will be stamped on the rotor....FYI......

I can not tell you how many folks got PISSED when I refused to turn worn rotors.....Store policy was we "MIC" b-4 we turn....and no we did not alwats get the counter sale BUT I never had someone come back and BIT@H me out either....

I would just get new rotors.

 

get new rotors and make sure to properly break in the pads, dont glaze them from too much heat early on

 

How about when you replace your rotors with brand new ones, a new set of $60 ceramic pads, and still get brake pulsation/shudder... That is what I am putting up with right now. I am 99.9% sure it is my rear drums. If I pull the e brake while almost to a complete stop I feel the pulsation. That may be your issue too? I am just going to get a set of drums and shoes.....

 

If you're that sure it's in the rear, have the drums ,mic'd, turned and ask for a nice non-directional finish put to them. I used to do brakes at Les Schwab and turned a lot of rotors & drums. After turning them on a lathe, it was standard policy to take a really fine grit sand paper/emry cloth and sand back & forth on the surface while it was spinning on the lathe to provide a nondirection finish. This made all the difference in the world as compared to only turning them. You could have "hotspots on a rotor or drum somewhere that could cause a pulsation too.

 

No I didt measure them but that is kind of what I was thinking with that many miles on the rotor and only having them turned once probably to thin.

So I guess its a new set of rotors for my taco. Dont want to cook my fancy new pads!!

 

You had said you got New Pads? Do the new pads require a special Bedding proceedure to set the new material? Some times if this is not done on the fist drive it can cause some of these same issues. But I agree with the New Rotors also.

 

I replace my rotors everytime I do my brakes. Cost wise, it's not bad, and you know they are new.

 

Sounds like rotor run-out , your rotors are warped even though they mic out within specs for turning probably time to replace .
