When you change the brake pads you really should put new rotors on or get the old ones turned if you can and put back on before you put new pads on. If you noticed when you put the new pads on, your rotors probably had some slight grooves and ridges in them. For your new pads to completely contact the rotor in this condition, they will have to wear down and mate up to the grooves and ridges in the rotors, thus shortening the life span of your new pads. If you have new pads with new or turned rotors, they both have flat surfaces and are matched up nicely. Your braking ability will be better improved this way as well.Hey everyone,
Just looking for some information about changing the brake rotors on a 2008 LE
I changed my brake pads this weekend and discovered that my rotors should be changed.
I dont have any quarrels doing this, as changing the pads was really easy.
Am I correct in assuming that all that is required to remove the rotors is the removal of calliper from the rotor?
As far as how to take the rotor off of the axel(not sure if its the axel.....whatever the wheel mounts too),
the two methods I've found so far are either using a two by four and hammering from behind or by inserting bolts into the smaller bolt holes(not sure if present on my car) on the rotor and screw them in until they force the rotor off(this is my preferred method if possible).
Are there other methods?
Any comments are appreciated.
I can't find any very good guides or videos on how to change the rotors specifically, so if you know of any id really appreciate you sharing.
Another thing to watch for is when you push the caliper piston back into the caliper, make sure you take the cap off of your master cylinder reservoir so the brake fluid can move back without any pressure build up. You can use a c-clamp and one of your old pads to accomplish this easily or buy a tool for about $5 or $10, but you will still need to use an old pad pushed up against the caliper piston.
To swap out or take your rotors off is fairly easy. I just did mine yesterday, new pads and new rotors, with the rotors that I took off that will be going to the shop to get turned. Unbolt the caliper from the caliper mount and take the old pads off. Before you do this though you may want to spray a little WD40 around the hub to loosen the rotor from the hub if it has become "frozen" to the hub. Then unbolt the caliper mount by undoing the two larger bolts from the backside of the mount. Use a 2x4 flat against the rotor and smack the 2x4 with a hammer a couple of times to help loosen the rotor. You don't want to beat it too hard though, give the WD40 a chance to work. You may get the lucky and the rotor may "fall" right off and you won't have to beat on it. My left side rotor was frozen but the right side came off no problem.
Now all you have to do is put the new rotors on or the old ones after they have been turned. Before you put the rotors on though, spray the surface with some brake parts cleaner to remove any dirt, oil, and/or grease that may be on the surface where the new pads will make contact. Then just reverse the order of the parts and put everything back together. Make sure you don't over torque your lug buts when you put the wheels back on though... 76 to 80 ft pounds of torque is all you need. Anymore than that and you risk stretching the lugs, or breaking them, or have them break while your driving.
Here is a link for a video that may help a bit. The guys likes to talk but he shows how everything goes back together. https://www.youtube.com/watch?v=uOjmEjSgUiw
Whatever you do, DO NOT use a screw driver to pry against the rotors. The calipers should lift right off without too much trouble.
