    How do everyone, looking for abit of info from you lads if possible.
    I'm in abit of trouble with my 2001 dt rear brakes.
    During restoration bleed nipple snapped off. I tried to drill and tap it. Unfortunately it didn't work out.
    Does anyone know what rear calipers will fit? Or is the only option upgrade?
    Any help would be greatly appreciated

      @wilson Hello,

      No I'm not aware of any particular upgrades. I run RS 125 caliper on my DTR

      But that requires some heavy modifications to do.

          @calum nice work mate.

          Is that the original bracket off the DT?

            @wilson Yes, well I have a DTRE, but it was an OEM bracket that was damaged.

              @calum 😲😲 nice job with that mate.
              Thank you for the help ill look onto getting a rs caliper. Did you go similar year or just any?
              What you running on the front?

                      @calum the caliper has both of it's mounting bolts at the bottom end of the caliper rather than the normally either side of the caliper unless I'm just looking at it wrong?

                            @declan Yeah not the best 😛 But must be good enough.

                            The worst part for mine is the adapter bracket is made out of aluminium so...keep an eye on it.

                                @calum @Declan The RS front disc is on the right hand (OS) side of the bike, so as the DTR/RE has the front caliper mounted on the near side (NS), which means that Calum's caliper is upside down. There may not be much wrong with that, but it may cause some issues with bleeding/air bubbles as the bleed nipple should be on the top. I had this issue on my ST185 Celica GT4, as I upgraded the rear brakes from the later ST205 model, which were bigger discs and 2 pot calipers. I mistakenly put the calipers on the wrong sides, so the bleed nipples were at the bottom and I could not get all of the air bubbles out, which meant spongey brakes. The issue was fixed as soon as I swapped the calipers over. Motorbike brakes are less sophisticated than cars, plus they have no servo, so it may not be an issue?

                                There's nothing wrong with Calum's set-up and I'm sure it works very well, but the mounting looks a bit weird, just because the caliper is upside down. If you get a front caliper from a Ducati monster, which uses the same Brembo unit's with a twin front brake set-up, just buy the left hand caliper, which will give you the correct left hand unit. You can then make up a mounting bracket to fit accordingly and the bleed nipple will be at the top.

                                  @ninja I was thinking of getting the "Brembo" one as it happens. I read somewhere that they suspect it's the same company that makes them all and they are just stamped differently. But given that my bike is not an Aprilia, it would be nice to have a generic "Brembo" brake stamp.

                                  Funny you mention bleeding, one caliper just refused to bleed no matter what, this caliper bled no problems.

                                    @calum You would think that having the nipple at the bottom would aid bleeding and reduce the air bubbles, but I guess that gravity plays its part and adds disturbance to the fluid? I suppose that bubbles rise to the top and having the caliper upside down may affect the flow as well? I'm no expert but I'm sure that there's been some study somewhere. If you look at most vehicles running disc brakes, the majority have their location's at the 2-4 o'clock position. I guess that's for maximum performance, it would be interesting to see if you swapped it for a left hand unit, with the bleed nipple at the top, would you get better braking performance and easier bleeding? There's always plenty of Ducati monster calipers on ebay and making a new bracket wouldn't take too long - well worth a shot. 😉
