I have used PF pads for several years, I wouldn't recommend them for a wet climate. They need to be hot and dry to work well. I remember one time after going through a car wash I went right through a stop sign into the street- I had no brakes at all. I even was going slow expecting them not to work very well.
Try out the ceramic pads mrblaine referrenced. I have them with my Vanco Big Brakes and they work fairly well when wet, much better than the PF pads ever did.
Last week we had quite a bit of rain (for Colorado that is) and I realized I probably shouldn't have thrown out the rotor dust covers. I'll bet they help keep the rotors drier when it is raining.
Sorry- dust shield. The part that likes to collect small pebbles and makes a loud screeching sound when trapped between it and the rotor.
Oh ok, yeah. Heh, I bent one of the dust shields once while doing something to the suspension. Hours later when I backed the Jeep out of the garage and it started screeching, it scared the hell out of me.
I'm also in wet Western Washington State. On my Cherokee, I had put Napa brake pads front and shoes rear. They were of a softer, higher traction compound than stock. They greatly improved my braking performance over stock pads and they cost LESS than stock pads. They never squeaked, not even when wet. The stock ones had been squeakers when wet.
However, I think they probably made as much or more brake dust as the stock pads. That makes for dirty wheels, if you care about that. The stock pads were bad for making dirty wheels too.
I wish I could remember what the name of that Napa pad was. They were awesome for performance, if you're not concerned about brake dust dirtying your wheels (which also happens with stock pads).
Now I do know that many after market high performance pads make much less brake dust, which keep wheels cleaner, and some of those high performance pads also give much better braking than stock.
I've also heard some good things about high performance Green Stuff brake pads. Anyone ever heard of those? What are your experiences with those?http://www.perfectbrakes.com
Check out their Green Stuff pads there in their various versions. I like the green cause they are for optimum braking peformance from 70 to 0 mph. The yellow and red are for 100 to 0 mph (sports cars and muscle cars). Obviously the green pads are best for Jeep application since we aren't (I hope) driving faster than 70 mph.
Also, the green pads are supposed to work good in wet and/or cold climates with no warm up needed. That's perfect for Washington State (very wet and sometimes cold).
Now those Napa softer, higher friction pads were also great on my Cherokee and I drove them for 60,000 miles and they lasted very well too. The Napa are less expensive than the Green Stuff. In fact, the Napa cost less than stock pads. However, the Green Stuff make less brake dust so your wheels stay cleaner and they offer the utmost in more stopping power.
With any brand of brake pads:
I never choose the high mileage versions because that means they will be harder, which means less braking traction and more rotor wear. The high mileage pads also cost more (typically). Why pay more and get less braking performance?
Softer (lower mileage) pads might wear faster, but who cares? They cost less to buy, and they don't wear out your rotors as fast. The NON high mileage (any brand) will offer a softer pad, which means more braking traction and better stopping, especially in cold and/or wet weather (no-warm up needed). Now whenever I say "better", I mean better in a cool and/or wet climate cause that's my situation.
I have no idea what is better in a hot, dry climate. My advice is for Washington, Oregon, Idaho, Montana, Canada, Midwest, and maybe Colorado. Also, for any place that is cold and/or wet much of the year.
I'd also like to point out that http://www.perfectbrakes.com makes high performance pads for your stock rotors, but also makes some after market rotors that might be very good, but not necessary for me since I use 33" tires. I think stock rotors with some improved performance pads are all I need for my LJ Rubicon. Stock rotors and the softer Napa pads were all my Cherokee ever needed with oversize tires and heavy after market bumper.
However, http://www.perfectbrakes.com does make high performance rotors, if anyone wants them. The make high performance pads for their high performance rotors, and also for our stock rotors.
I've never used their products, but I am very interested in them. So if anyone has experiences with them, please share them. I'd love to hear it cause I might want to use them on my LJ.
My only upgraded pads so far were the Napa softer pads on my Cherokee, which were actually considered a downgrade from stock since they were softer than stock with a supposedly shorter mileage life. However, those softer Napa pads had better performance than stock and lasted 60K miles and still had half their life left on them when I had them checked. So they were great pads that cost less money than stock.
