So I think I'm going to get drilled/slotted rotors for the Journey as the brakes are coming due.

Having never used this type of rotor before I wanted to know from your experiences what the best pads to go with are. Keep in mind I operate this vehicle like a fleet vehicle and it's on the road daily for lots of miles.

I can get Fleet Rated Extreme Duty pads that are semi-metalic or I can get ceramic pads or I can get standards daily driver rated semi-metalic pads.

Thoughts?

They look nice but is there any advantage to using drilled/slotted rotors on the street?

Word of advice - DON'T.

I have them on my SHO - the Powerstop set. Mainly got them for a possible slight increase in the brakes, which in the 2010 model were simply adequate.

Never again - put them on at 75k and now at 120k They are noisy under hard braking, have a slight warp to them which nobody will machine out and all in all are not anywhere near as good as I hoped. Hoping to get them off in the Spring.

Nope, don't do slotted or drilled Stevie.
I usually get my rotors/pads off eBay.ca from well rated vendors. Bought the last set this spring, was anti-corrosion coated "normal" rotor with ceramic pads - for 4 wheels. $180 delivered.
My best price was for a 2005 Uplander - 4 rotors and matching pads - $132 out the door in Toronto local pickup. They still worked fine after 2 years and 45,000kms, and I disposed of the vehicle.

Do not bother with drilled or slotted rotors on the street. Will give no braking improvement and will just wear pads faster. Those kinds of rotors are meant to reduce brake fade by managing heat better than a solid rotor. You are not going to experience brake fade on the street in a minivan.

If you want better brakes, get a quality solid rotor like a centric blank and a quality high performance pad.

I was just after longer lasting rotors and I thought I would give the drilled/slotted a try only because I operate like a fleet vehicle and they are well used.

I guess I will go with a quality vented rotor that is corrosion treated and ceramic pads then...

What do you mean when you say longer rotor life? Longer until they are too worn down to use or longer until they become "warped"?

Longer because of warping. The Journey has insanely large pads so they last forever. I'm approaching 100,000km (60K miles) on original front/rear pads in frequent stop/go driving and have about 30% left! crzy

I had slotted/drilled rotors once. They under performed and fell apart [rusted] surprisingly quickly. Never again.

Get high carbon rotors they last a lot longer. Napa's ultra premium rotors fit the bill.

Napa anything here is usually gangster expensive but I will check into high carbon. Thanks! thumbsup

High carbon should be coated, right?

Also, I see no connection between drilled/slotted and rust … I have a set that’s a year old and a “Drivers Side” decal is still stuck to the rust free finish …
