Changing Brake Pads Back/Forth?

BGTV8

I've never bothered machining rotors when changing pads.

I get 8-10 track days and 20-30,000 klicks per set of rotors, usually 2-4 sets pads per rotor change

I choose pads from Ferodo DS2500, Endless MX72 or PMU HC+ for combined street/track duty, but every year I run in a teams-based 6-hour enduro (each car gets around 1-hour in the event) and for that, I usually run Endless ME20 pads (unless it is wet, in whcih case I use my regular pads as keeping heat into ME20's in the rain is a challenge).

For me, it is all about bedding the pad to the rotor, let everything cool down, and get on it.

I might care a little more if there were serious bragging rights attached to a track-day outcome, but I leave that for the "proper" race car.

Don't cut your rotors. Unless you warp them on a track day (guilty).

Swapping pads is fine... i've been doing this for my last 3 cars and 25 track days.

NOTE: re-bedding is required sometimes
