Questions on brake rotors

Oct 20, 2007 5 Replies

I am getting ready to do my front brakes on my 99XJ, the store lists two different rotors for it, on is listed as full cast rotor, the other is listed as a composite material? What is the difference, I have 150k on the original, with them being turned about 75k ago, but in ease of time I am going to replace them.



TIA

Composite rotors tend to warp and cause problems. I would avoid them.

What is on there now? If you got 150k out of them, try to get the same thing for a replacement. I am guessing cast, but you could take the old ones to the store and tell them this is what you want for the second 150k.

Cheers,

Still has the factory rotors on them, I am assuming full cast rotors, I purchased a set of Wagner Full cast rotors today, now if I can find my c clamp to collapse the piston in the caliper....

I just use a pry bar of some kind, putting firm, steady pressure on the pistons and they just push back in. Most likely you had factory composite rotors and you were lucky to have no problems with them. Good choice on the cast rotors.
