rock auto.com is just another discount parts company and they sell decent parts. If you want the best peace of mind for a Ford, use OEM Motorcraft pads.
I have not used any pads or shoes form other than Brake Best from O'Reilly, WearEver from Advance and a couple of sets of Duralast from Autozone since about 1994!!
I get long life out of them and they work properly and you only have to buy the ONCE.
I see no reason to buy anything else, especially one with no lifetime warranty.
After getting scolded by another member here earlier this week I will share this quote from a member on the lincoln forum:
"I have a really noisy Motorcraft reman one on my car. Its awful but it works well and has been for years. I sort of wish it would die so I can replace it with one that doesn't sound like a dying air raid siren. The used original Ford one my friend gave me for the Continental is not audible above the engine under the hood."
A classic example why I have repeatedly told people you are usually better off with a nice looking lower mile factory original one from a junk yard than ANY reman and most new ones.
I come across as very opinionated -because I am- but I didn't just pull these opinions out of thin air or from what I read online.
I have been wrenching on, buying and selling, maintaining a fleet of personal and commercial business cars, MCI diesel pusher bus, fire truck, F350 with 44 mudders, 91 Ram Charger with 6in susp lift and 35s, 98 durango with 11 inch susp and 6 in body lift on 365/70-18s, 67 GTO running 11.70s, and a few other old classic cars and various trucks and daily drivers.....
since 1988.
I can guarantee you I have spent less money per mile by buying non oem parts (even if some didn't last quite as long) than if I would have bought OEM or went to Napa or Genuine or Main Auto Parts (in my area).
I don't get the I feel better because I spent $75 more for my brake job.
I feel GREAT when I can hear a wear indicator touching and I pull the wheels off and the calipers are free, the pins move with mere finger pressure, the piston goes in easily, and I only have to put a new set of pads on and it's good for several more years.
As far as brakes go, most when cars get older, do not wear out evenly or due to the miles of their lifespan being put on them.
Most end up with uneven or inner or outer pad wear from sticking caliper, pins, sliders, hose etc.
Even the best brakes are not going to give expected life when something else is shortening their life.
There are only a couple of things I have found to be too low of quality to bother with that brand.
