break problem.......
 

I boughty my Mazda 3 almost 2 years before, now I am having problems with thre break, as soon the car goes to speed of 60-70 miles, if I push the break, the steering starts to shake, I thought it was a problem with tire, as I have to change a tire but after they balance the tire, I still have this problem. I dont' know what do ...... should I go to dealer or should I go to regular shop, I am really worried abot the cost...................can any one give me a suggestion about it....................

your rotors are most likely warped. i would buy new rotors and do it myself. if your not mechanicly inclind just bring it to a local shop.

See if you can turn your rotors 1st. befor you go buy new ones. EBC new stock rotors are good and cheap.google it.

Would probably cost just as much to turn them as it would to buy new ones. It's not like the old days, you can get excellent aftermarket rotors for relatively cheap now.

Well my guy turns rotor for $5. 4 for $20 . now you can get 1/2 rotor for that price....lol

Can't very well argue with that now.....can I????
Damn good price! :bt:

Before turning / replacing make sure there isn't a dragging caliper. That could heat things up and ruin a new set of whatever you put on.
Look at the rotor wear surface as well, it should be shiny, any dull or dark spots, or shifting color on the rotor means it's probably toast - AKA it's corroded from the inside out and cannot be fixed.
If you have any doubts just replace them, and the pads, then you'll know tnat everything is good instead of using multiple days pulling parts and replacing different things.

That is classic for warped rotors... change out the rotors and pads - and do a brake fluid flush while you're at it.
Same problem as you stated with your first post, and this is the same advice.

Good luck.
