    looking to buy replacement rotors and pads. questions:

    1. 348 and 355 have same brakes?
    2. front pads and rear pads seem to be of same shape? only difference is front has a wear sensor?
    3. front rotor is Ferrari part #160051, rear rotor is Ferrari part # is 160052. So it is a different part number. search show someone mention front is 300mm, rear is 310mm in diameter. If that's the case, how can they use the same pad shape? bit confused here.
    4. Brembo shows a part # of 09.4966.10 for rear rotor (Ferrari part # 160052). anyone know where to purchase these Brembo rotors? Googled it, and can't find any available.
    5. where are everyone buying their brake rotors?

    thanks.

    Sort of! LOL

    Early 348's use Teves calipers (easiest way tell tell is that "ATE" is stamped on the back in raised script). Later 348's use Brembo calipers - same as 355.

    Early 348's have a narrower rear handbrake shoes so the top hat part of the rear rotors is not as wide. IIRC the early shoes are something like 25mm where as the later are 30mm - perhaps someone can chip in to confirm. If I understand correctly you can fit the later rotors over the narrower shoes no problem but not the other way round as they wont fit obviously. However, if you do fit the later rotors you may want to take the opportunity to fit the later wider shoes but if you do this you will need the later longer pins to hold the shoes in place.

    Handbrakes are the same including lever - I actually fitted a 355 lever to my early 348.


    Yes. BTW You may find your sensor crumbles apart when removing from pad but you can buy a maserati one for very little and just recycle the plug.

    If you go here you will see that the part #160051 fits both early and late 348 plus 355

    and part 160052 appears to apply to both..

    https://www.ferrariparts.co.uk/part/ferrari/160052?id=5115


    In the UK so may not be appropriate but they sell brembo kits here (plus you can work out what fits what ):

    Hope this helps! :)

    Here are my findings from the time when I was, ~ 5 years ago, replacing the Teves (Ate) calipers on my 1991 348 with Brembo calipers (I cannot guarantee that the rotor sizes shown below are correct, just the info I found at the time):

    The 355 rotors are 310 x 28 on front and 300 x 24 on the rear. The 348 has 310 x 24 front and 300 x 24 rear. I was replacing the calipers only, kept the original rotors. I bought a pair of used rear Brembo calipers from a 355 and they fitted perfectly. For the front, as it appeared that the 355 Brembo calipers would not fit as they are for thicker rotors, I bought new front Brembo calipers from Eurospares, p/n 143728 & 143729 (RH & LH), which were listed to be for 348 only and the 355 front calipers were listed as p/n 169825 & 169826 (RH & LH). This made me believe that info on the different thicknesses of the 355 & 348 front rotors, 28 mm & 24 mm respectively, was correct.

    Miro, I'm not 100% I understand what your problem was but if you look on:

    https://www.ferrariparts.co.uk/Diagram/ferrari/348-tb-ts/033-calipers-for-front-and-rear-brakes?part=134090

    You can see all the variants of original calipers.

    Note also item 10 on the diagram - ie the spacers - if you click on thois you can see there are many different sizes that you can add to the inside of the caliper to move its position in relation to the rotor (ideally making it central in relation to caliper). Its not that you needed to add/remove the spacers was it???

    any tricks? their online price is $83 per rotor, but when I asked for a quote. They (USA) quoted me $330 per rotor.

    thanks.

    I had slight binding of one of the rear Teves calipers. As I could not find a seal kit for it anywhere at the time, I decided to replace all calipers with Brembos as seal kits for them are easily available. I had a chance to buy good used 355 rear calipers locally and, when I checked the 355 and 348 rear rotor sizes, I found them to be the same, bought the used 355 rear Brembo calipers and they fitted perfectly including being well centered over the rotor using the original shims as they were placed.

    Then, I thought of buying used 355 front Brembo calipers as they appeared easier to find on Ebay. But, as I found that the front 355 rotors are 28 mm thick, meaning wider "jaw" of the calipers, and the 348 front rotors are 24 mm thick, I just bought a pair of new front Brembo calipers (p/n 143728 & 143729) that were specified for the 348 at the Eurospares website.

    Perhaps calipers made for 28 mm thick rotors would work ok over 24 mm thick rotors but the caliper pistons would be 2 mm out at each side to start with and the pads would need to be replaced 2 mm of their thickness earlier. Changing pads earlier is, of course, not an issue but I was not sure whether 4 mm (2 mm at each side) wider "jaw" calipers would be safe to use. The jaw width of the Brembos 143728 & 143729 is the same as what the original Teves ones had for my 24 mm thick front rotors and centred correctly with the original shims.

    Why aren’t there more drilled or slotted options available?
