    Default 2014 RT Limited Left Front Brake Caliper Leaking.

    My 2014 with 1000 miles has a leaking L/F brake caliper . I look at a replacement and see that it has a $264.00 price tag on it. Is anyone aware if there is a rebuild kit available for these ?

    It's uncommon to have a brake piston seal fail at such a low mileage, I'd be tempted to dismantle the caliper and check the seal for a little debris or contamination and check the piston for a longitudinal scratch. Be sure to remove the seal from its groove (carefully!) and check the groove for debris or left over manufacturing swarf. I've seen it happen so it's not just a guess.

    Fingers crossed, you may get lucky.

    I assume it is leaking at the piston? You want to be sure it is not leaking at the bleeder or brake line connection. If it is the piston, I'd be inclined to dismantle it as suggested by PRP. You'll have nothing to lose. If I were to replace it. I'd go with a used one. These have proven to be extremely trouble free over the years. Like this one on eBay. I'd say it will do you as good as a new one.

    Good luck!

    Another great tip ! Never thought of eBay.

    I have a friend who races Trans Am II and he hooked me up with the company that handles his caliper repairs. They are confident that they can reseal it as they routinely deal with Brembo .

    The caliper is in a box and will be on it's way to them in the morning. A bonus is that they will pressure test it when they are done.

    Can't believe there isn't a kit available for these just an expensive replacement.

    Where did you get it done? I've already ordered a replacement for my font left caliper, but it would be nice to know wher to get it fixed if it happens with one of the others.

    The shop is in Mooresville NC . If they are successful I'll post the name and contact info.

    Does anyone know the front caliper bolt torque spec ?

    Great information! Though I assumed there were places to get Brembo components worked on. I was not aware of any specific vendor for this kind of service. Very anxious to hear the results and pricing.

    I think brake system manufacturers quit offering rebuild kits due to liability issues. It is a shame that all these legal claims have gone a long way towards limiting our options.

    Well Ron you are exactly right about the liability issue subject.
    When I called and talked to these folks about repairing the caliper the gentleman was hesitant at first because it is a motorcycle caliper and they are not a motorcycle shop.
    My friend does a lot of business with them and that may be the only reason that he is willing to fix the caliper. I had to assure him that I don’t sue people that do favors for me, it fact in my 62 years I have never sued a soul.
    It is a damned shame that it has come to this.

    Sounds like you've got this worked out. But you might want to impress upon him that it is a 3 wheeled, reverse trike with a very good VSS, Anti-Lock braking system. Not nearly as Litigation Prone as a 2 wheeled vehicle might be.

    As I said, very interested in the outcome here. Though it sounds like it may be a 1 shot deal. If this goes well, your provider might be open to more Spyder/Ryker business!

    That's very annoying. We disassembled the caliper - it's leaking for the outside rear piston from the looks of the residue. Pulled all the pistons, cleaned everything as well as possible and re-installed and it's still leaking. Its just one piston seal, no dust seal, you'd think they'd be easy to source.

    You can try Apple Hydraulics in Caverlton NY
    I have used them in the past for automotive calipers.

    This is where you have to be severely logical with yourself... there must be a fault you missed, perhaps a scratch on the piston, a nick in the seal, a bit of debris or even a hair line crack. Square section seals can be purchased and square section O-ring cord can also be purchased so you can make your own seals. Google will be your friend.

    During my quest to find a rebuild kit I spoke to a Brembo dealer, nice guy and he seemed to know his business. He said that there was an internal o ring that sealed the "crossover passage" between the caliper body halves. His claim was that if this o ring was bad then the caliper would leak out of the body and not the bores.

    Never took mine apart so I don't know if he is right or wrong.

    I think he is correct, that is common practise, sometimes it's a round section O-ring and sometimes a square section O-ring. Extremely unlikely to leak unless there was contamination at the build time. Mind you, I'd say that about the main seal too.
    Just for completeness, a main seal fault I've seen is for the square section seal to be picked up for a wee length by the insertion of the piston and it roll 90 degrees in the groove. It sealed for a time but then began to weep.

    Kind of strange that there's be a seal in a crossover passage. Near as I can tell, the caliper is one piece, it didn't have two different halves joined together.

    Yes, I could possibly have found the proper seals for it, but that requires some seriously accurate measurements that I'm not confident I could do. So I'd either have to send them out, or just keep trying different sizes till I got it right. Either of which puts the tryke out of commission for a while. Maybe if I get a mind to, I'll pull it apart again after the replacement comes in and start the hunt for seals for next time.

    And yes, we could have missed something - we're older and our vision may not be the best, but everything felt smooth as best we could tell. But with the pressures brakes are under it doesn't take much for a leak.
