    Ony my 575M, I guess same for 550 and 456:

    I want to remove my brake calipers to inspect and clean them, and the area around. I understand I have to undo the brake hard line at the back. Does anyone know what dimensjons the (F) feed line and caliper end has? I guess I have to find something that fits to block them both off while they are off, so I don't make a total brake fluid mess, or get water in the caliper or line.

    u can unbolt the calipers from the bracket and move the caliper around w/o undoing the brake line.

    that should allow you access to do some cleaning w/o having to bleed the brakes, etc

    I assume it is an M10. Pretty standard size for brake components.

    So for the record I used 3/8 UNF bolts with some thread tape in the calipers, works fine. I couldn't find any caps with the same dimensions for the lines so I just used a vinyl glove with some rubber band on them to keep the fluid from dripping.

    A real ****ty job, but very rewarding when you're done. I will also recoat the discs while I have them off, so it should come out a lot nicer than before.

    Before and after

    So just cleaning? No intention to flush the lines? no caliper rebuild of seals? no pad change or rotor servicing? Resuse of 25 year old rubber brake lines?

    I’ll replace the fluid once they are installed again. Everything else looks good, even the seals. The car has 14000 miles on it and it looks like they were captain slow miles too.

    I would change rubber lines no matter how little km's they have if they are anywhere near original from factory.

    I sent the question to Goodride, they ("Zoe") just replied that they don't have a kit for the 575M. Apparently the customer center person don't know anything about if the other kits will fit anyway.

    Does anyone here know?

    Looking at this for the 360: https://www.eurospares.co.uk/Ferrari/360/360_Modena/PartDiagrams/043/Brake_System?ref=018

    and this for the 550:
    https://www.eurospares.co.uk/Ferrari/550/550_Maranello/PartDiagrams/040/Brake_System_-Not_for_GD

    It looks like the 550 has rubber hose into the caliper, while the 360 has the same setup as the 575M with the hard line into the caliper. So my guess will be the 360 kit.
