I am about to replace the rotors on my Disc brakes . They have done over 100K and they getting to the minimum thickness recommended. Is there a problem with the wear of the rotors that have holes drilled in them ore slots machined through them . Do they wear the pads or do the slot's and holes block up
thanks
Terry

You don't' need slotted or cross drilled disc rotors. Slotted/cross drilled rotors were originally developed for racing/competition vehicles that really hammered and heated the brakes. The theory is that the drilling's or slots release/prevent a build up of superheated gas between the rotor and the pad and so maintain friction.
Boy racers and wankers might specifically specify them, you and I don't need them. However! If they are offered at a more competitive price than a standard rotor I would be happy to fit them, but no way would I pay a premium.

I just fitted cross drilled rotors to my 80 for the main reason that Ian W stated. "To get rid of the gas build up between the pad and rotor." I will do anything to attempt to get rid of that terrible DTV or brake shudder.
I have a link on my website I wrote about brake shudder which makes interesting reading for those whom may be interested.
DBA rotors are quite competitively priced these days. They were considerably more expensive a few years back and companys like Protex, RDA etc were heaps cheaper so DBA came into line. They do make a better product in my opinion.
