You replace rotors when they get too thin, or are warped. They may be to thin to be turned and still alright to use. Rotors do not "have to" be turned to put new pads on.

Why is there a grinding sound coming from the front tires and there is no squeaking at all?

brake pads are worn to the metal rivets. You will need to replace pads and rotors. rotors are $35 each and pads are $29-59 for both left and right side.


Can you cut rotors on a 2004 dodge Dakota?

If they have enough thickness left to still be above legal minimum thickness after the resurfacing, yes.


How do you remove the front rotors on 1988 Chevy Sprint?

First remove the right and left tires, and then proceed to remove the rotors. After you have replaced the rotors put them back on.


Do brake rotors have right or left?

no unless they're drilled rotors which are on the very high end of the rotor market


When do you need to change front brake pads and turn rotors how many millimeters do they start out at If there are 3mm left and do they need to be replaced?

The pads need to be changed when they wear out. That is determined by how you drive. Can be as little as 20,000 miles or as high as 60,000 miles. Once you hear the warning signal, (Squeal) that the pads need replacing, if you immediately replace them you can easily have the rotors trued and not have to replace them. If you ignore this warning, you may end up replacing the rotors. Any good machine shop will tell you if they are too thin to turn.


Why is thereShaking when brakes are applied on 2003 impala?

warped brake rotor or drum The shaking can be caused by the rotors being warped out, it can be fixed by ither get the rotors machined "turned" if there is enough metal on it the mechanic will measure it before he turns it, if it do not meet the thickness requirement, then you must replace both rotors, left and right along with the brake pads too, and also I highly recommend to replace the brake calipers too, since they also can be worned down to where it can be a hazard, and to have your brake lines and master cylinder cleaned and flushed out. Also have your back brakes check out too along with the drums or rear rotors too, and also I recommend to replace the brake cylinder or calipers which ever the case might be.


When do you replace brake shoes on cars?

When the shoes/pads have less than 10% of lining left. When shoes/pads are cracked or damaged. When the drums/rotors are replaced.


What are squealer pads for?

Some brake pads have a 'squealer' plate attached. This thin plate does not do anything until the pads become badly worn. Then the plate rubs against the rotor, squealing (emitting a high pitched singing noise) letting you know you need to replace the pads - before they damage the rotors. Without this feature, pads wear out then grind deep grooves in the rotors that then have to be resurfaced (ground smooth again if there is enough metal left) or replaced. So getting pads with this feature saves you from having to replace a set of expensive brake rotors.


What would make a 97 jeeps brakes to pulsate?

Warped rotors. Driving using the left foot to brake causes the rotors to heat up. Quenching the hot rotors by driving thru water will cause them to warp. The warped rotors cause the pedal to pulsate.


Your car shakes some times when slowing down?

If you mean that the brakes "pulsate" when you apply light to moderate pressure... that's caused by a warped rotor. If a rotor overheats it will warp causing disk brake "chatter". Sometimes the rotors can be turned to make them "true" again, but often you need to replace the rotors. I generally do both front rotors at the same time so that there is no difference between the left and right brakes.


How do you rotate rotors?

switch sides...ie..take the left and put it on the right side..land right on the left


Possible problems on a 2000 Focus with grinding noise before and after new brakes?

I had a similar experience with my Windstar - lots of pad material left, but still grinding after new pads & shoes. Turns out the rotors were bad. :( Btw, I just replaced the rotors without finding out if a simple turning would have eliminated the grinding.


Why would a 1990 Honda Prelude squeak on the front left wheel?

I had a squeek in my left front wheel, everytime i went over a speed bump etc. Turned out it was a torn cv boot.If this is the case you need to replace it immediately or you will soon need a whole new axel. It can be the rotors or break pads.


When a condition described as a pulsation when the brakes are applied what should be done first?

The first thing I would check or do would be to remove the rotors and check their condition. If they have enough surface left, have them turned to get them true again. If they can't be turned, then replace them with new (which should also be turned or at least checked .The most common cause of pulsating brakes, I have found, are warped rotors. This is usually caused from overheating.


Can you put disk brakes on backwards?

In 99% of cars, no. The only exception to this is if your rotors are drilled and/or slotted in a directional way. If your rotors are just normal ones, there is no such thing as a left or a right rotor.


What are the signs that your brake rotors are going bad?

Several things to watch for. Your brakes will sometimes start to stutter or pulse as you apply them. Occasionally you will hear a noise like a grinding or a squeal. With any luck, it'll be the pads wearing out before the rotors get damaged, but that''s not the way things usually happen. People have a tendency to let things go until more work is involved. If addressed soon enough, most rotors can be turned and used again, If left too long without attention, you will need to replace the pads, the rotors, and sometimes even the calipers, so...best to take care of things as soon as you can.


Why would brakes on a 2003 Ford Focus still squeak at low speeds when both front and back pads and rotors have been replaced?

Either someone left the sound suppressors off or/and didn't spray with the soundproofing.


Can brake rotors cause a rubbing noise when turn right or left?

Sometimes not all the time


Why would front brakes on a '98 Ford Taurus start squealing a few days after installing softer pads and applying Disc Brake Quiet to the shims?

Check the rotors see if they're smooth inside and outside. If they're not smooth, or if they're so smooth that they're shiny like chrome (which brake pads can't grip as well), you can get them milled at some auto shops, but also check if they're still thicker than minimum allowed thickness (this figure will usually be marked on the rotor). If they're at or below minimum thickness, replace the rotors (replace both left and right side at the same time, so both wheels brake as identically as possible, so the car doesn't pull to one side as you brake). You may also need to replace the brake pads with higher-quality ones.


Why does your truck pull to the left when braking?

Brakepads or rotors need work; take to shop ASAP to diagnose and repair.


What is the lifespan of Toyota Highlander brakes?

I have a 2002 Highlander and did not replace the pads until it had 110K miles. I am pretty easy on brakes but was still surprised they lasted that long, and they still had some pad left. 2.4L 2WD.


What should a brake job cost on a 1994 Escort?

Usually Just Brakes will charge $99 sometimes more if rotors or calipers are damaged = Front Brakes & Rotors = I just had mine replaced (14" Rotors), cost me $74.23 for the parts. 2 New Rotors, and 4 pads. Now changing them is a different story. My 1996 pads are mounted on tracks, that slide left and right. Held by 2 pins each. Really scary, especially if they are half-frozen.


Do left and right rotors need to be replaced at the same time?

Yes, both rotors should have the same type of finish on them for even braking. They could both be new, used, or both resurfaced.Yes, both rotors should have the same type of finish on them for even braking. They could both be new, used, or both resurfaced.

How wheel discs are tested?

If you are speaking of disc brake rotors, the thickness of the rotor is measured with a micrometer to determine if there is enough material left to reuse or machine the rotors for service. Each rotor has a specified minimum requirement. To reuse a rotor that doesn't meet the minimum requirements is illegal and unsafe.
