I am planning to get new zee brakes. i am currently running avivd trail brakes.

Is it essentila for maximum braking performance to buy new disks or can i simply brake in the new pads on the old disk?

As long as you make sure you properly clean, it'll be fine. Usually I use some fine sand paper (400) and sand the rotor slightly on the braking area, and then clean with whatever I have on hand, brake cleaner, isopropyl alcohol, ... of course don't use any "greasy" product to do so.

By the way I must still point out that depending on how old or worn your current rotors are, you might still get more power out of fresh new rotors.

It's just that it's not always necessary. I've used old rotors in the past, and it was completely fine using them from a brake to another. It sometimes needed a longer break in period, but it's eventually comes out fine Smile

i measure them with a pericsion caliper and one is 1.899 mm the other 1.756 so they should be fine for a while its jut the budget is a bit tight and new disks would strech it Wink
