Probably warped brake rotors. They can be taken off and machined true or just replace with new rotors.
I have found that new rotors are in need of turnig even though they are NEW. They tend to have not been machined with tight tolerances because they are mass produced. You may not feel anything in the break pedal but, if you do you have to take them off and do all that work AGAIN.
If your rotors are worn you should replace those as well. Worn, warped, or glazed rotors will reduce the effectiveness of your brake pads and possible wear them down faster. As far as the possibility of doing so, sure but it's not recommended. Just to add a comment, depending on the rotor thickness, the rotor surface should be machined to remove the glaze or warpage before installing new pads. Machining of a rotor surface reduces the thickness. If a rotor surface has previously been machined the rotor may need to be replaced.
Disks out of round, worn or warped will cause the brakes to vibrate. You need to have the rotors ispected and machined,if there is enough thickness let on them. If this does not fix the problem, you need to install new rotrs.
As long as your rotors are not warped, or you have not let the brake pads wear to the point they defaced the rotors, there is no need to change them. Just install new brake pads. Rotors can last the life of the car.
Many dealers charge any where from $210 - $350. It all depends on the rotors, if they can be machined then it will be toward the lower end.
Typically rotors come from the factory covered with a waxy material to prevent rust. Yes, it's a good idea to remove that material before using the brakes.
One of the two brake rotors on the front is warped. You can either buy new ones or get them machined if they aren't very old. sounds like one of your rotors is warped.
More than likely you have warped rotors. Have the rotors and brakes inspected. If the rotors are not too bad and have not been turned before they can be turned and trued and used again. You will also need new brake pads.
If the rotors are in good condition, not warped, not scratched, then you can replace the pads without turning the rotors. Inspect the rotors carefully.
No you do not have to get new rotors just have them resurfaced. If they are to much warpage then you may need new ones. I would try getting them resurfaced before you replace them.
There was a lot of squeaking while braking when my car needed new rotors.
Your rotors had the grooves before, from the old pads. You should have had them turned. Next time check rotors at time of fitting new pads. If you can see or feel grooves then they should be repaired.
No, unless they are rusted.
remove tire calipers brake assembly then pull your rotors off i would recomend putting new brake pads if your putting new rotors you will need a special puller for the rotors cause they are pressed on
A frozen brake caliper or if you just instaled new brakes and rotors you might have oil on the rotors as they need to be clean before installing.
You probably need new rotors
you probably need to get a new head or have your head machined
the only other parts you might check when you have it pulled apart,are the wheel bearings.the bearings etc are in the rotors but do not come with them when you buy rotors.if you are not careful you will trach the bearing races and seal on the back side of rotors when trying to remove them to install in new rotors
The majority of the stopping power is performed by the front rotors. I would start by replacing them.
I don't know if you are saying you have the new hubs and rotors and still have pulsation, or if you are asking what causes pulsation. If you have pulsation on slowing this is due to warped rotors, and you need to change the rotors and the brake pads, not the hubs. Not too expensive: 2 rotors and brake pads for my Pontiac is about 55 bucks. DIY of course.
any good mechanic can do a set of rear brakes in a matter of minuites, assuming your drums or rotors are in good shape and can be machined. (machining process may take 30min or so) as to price, most places have a pre set price. Tires plus for example has a preset price of 89.99, this includes pads or shoes, and machining of drums or rotors. if you need new drums or rotors, or if you need any springs or retainer bolts, this cost will rise accordingly
new rotors are good to go from the box. just clean them with a brake cleaner before you install the pads, as rotors have a thin protective film on them to prevent rust etc in shipping and storage
Your rotors are warped. You need new brake pads and the rotors turned at a machine shop or replaced.
You will need to remove the tire and wheel. You can remove the brake pad and break assembly, by removing the brake spring and caliper. Loosen the rotors with a hammer. The rotors will slide off. Reverse the process to install the new rotors.
