    I checked recent archives before posting. I am looking for front pads for my '84 400i. It appears that several larger BMW's use the same pads. I am happy with the pads I have but I am not sure what brand they are. The most prominent marking on the back of the pads is "265-5" in white paint. Does this appear to be a Ferodo number?

    The archives indicate one person being very happy with Porterfield R4-S. Any other positive opinions on these?

    How about Ferodo? Which composition for street use? T. Rutlands has the Ferodo pads on ebay. Are these recommended?

    Sorry but I don't know. However Aidan has done some research on pads, check his posts or shoot him a PM.

    I have Ferodos (not sure of exact type, but I think they are the OEM type) on my car now - they seem fine. I tried EBC Greenstuff and they seemed noisy.

    Based on this thread and and info I have gathered, my choices appear to be:

    - Ferodo OE pads which I will be comfortable with and recommended on this site
    - ATE pads which is what I now have and am happy with
    - Porterfield R4-S which have been recommend

    Since they are common with several years BMW 6 and 7 series cars one could go to NAPA and save some bucks but for brakes I am not interested. I have not yet found a definite source for the ATE's but I have some phone numbers. So I think I have 3 good choices and $10-20 difference is not going to sway me. If anyone has had a BAD experience with any of these let me know.

    I've used Porterfield R4-S pads on my street Ferraris from a 1959 CA Spyder, 4cam, Daytonas, GTO, 512TR, etc. with great results. My favorite pad is the Raybestos ST41/43 combination. But, that is supposed to a track only pad. I've been using it as a daily street pad on my GTO and one of my Daytonas with fine results. In theory, they should be squealing and not be up to temperature in street driving, but they don't squeal and they stop great, even when cold. They are expensive though.

    The R4-S stops fine, doesn't squeal, and is easy on rotors.

    Your input is great; must be nice to have such a collection of "test vehicles". Price I got from Porterfield was less than OE Ferodo pads. Sounds like a winner.

    All Steve needs now is a 400 to round off his collection!

    I restarted this thread due to a little problem. I opted for the Porterfield R4-S pads. I just tried to install them and they are about 2 mm too thick. They do not even fit between the caliper and the disc never mind between the piston. They come with their own noise reduction plate on the back of the backing plate so I tried to install without the noise plate that was on the car. They are just too thick.

    Anyone else have this problem with Porterfield or other pads? Porterfield is closed today so I will talk to them on Monday. It looks like I may be back to ATE or Ferodo; both good choices but what a pain!

    Ken,
    Any chance that you could surface grind the pads down a couple of mm's or so to be able to experience that Porterfield difference?

    I thought about doing that, but I want to talk to Porterfield first. When you get their pads the invoice is stamped that you the buyer is solely responsible that the pads are applicable and that under no circumstances are they returnable! Hmmm, they are the ones that told me these pads are correct.

    If I had the right tool for the job I would do it myself. I could buy alternate pads for the cost of getting a machine shop to do it.

    I'll let you know what Porterfield says tomorrow.

    Ken,
    My server is down so I can't get to my docs but I remember that you can use any pad that crosses to a Hawk HB206.565. The .565 is the thickness and the HB206 is the outline. BMW used the same outline but both thicknesses and various cars. The other thickness is something like .7 or so and is way too thick. Don't bother trying to shave them, much more of a pain than its worth.

    Got to go now because In-A-Gadda-Da-Vida is on the radio.

    Good luck.

    Mark is completely correct. Porterfield supplies these pads in 14.5 mm and 18.5 mm thicknesses. They are shipping the thinner ones and will refund me for the thick ones. There was no questions about the refund. They use an alternate part number AP 82 for the thin ones and AP 163 for the thick ones. I think they may update their application chart to show the thin ones for the 400; they originally gave me the AP 163 as being correct for the car.

    Bruce, Porterfield handled this very well.

    The reason for the diffence in thickness on the Porterfield pad is that some Ferraris use thicker vented rotors and some use solid rotors. The brake calipers are the same except for some spacer between the caliper halves, but the pads are thinner for the vented rotors.

    Oh, and you will be happy with the Porterfield R4s compound, it's the only pad that I recommend.

    Several months ago I put Porterfield brake pads on my 1980 400i at the same time that I had all of the calipers re-built and also stainless brake lines (8) and new wheel berrings..WOW!!!..Perfecto..Portefields are simply the best pads that I EVER put on any car that I've ever owned (30)... Just one thing that Porterfield suggested to me...Try to warm them up for the first few times that you drive off..this really makes for perfect fit..and very litle dust (if any).. stops on time and nooo noise..I like them even better than the Ferodos and very reasonably priced..Jacques..over..

    Yep! But my calipers need rebuilding first, as I've got new Ferodos or ATEs in now.
