  • NB Miata rear calipers leaking

    I just finished removing the e brake mechanism from the car and calipers and now the shafts that the emergency brake cable attached to are leaking. I bought a caliper kit from Mazda and replaced both shaft seals, but they're still leaking badly.

    I'm thinking I removed more than I should have? I'm pretty sure I removed the adjuster screws, which is the reason the shaft seals are leaking. Does anyone have any suggestions/wisdom?

    Can we get a picture with an arrow?

    Iirc the adjuster and bolt cover stay.

    The procedure should have been to just rip the guts out of the piston. Everything else can stay. E brake cable can go.

      I picked up two used calipers thanks to Red_5 so I'll just start over. I think what's causing the leak is that I didn't put the adjuster screw back in the piston bore, which has an O ring seal at its base.

        I took these out and didn't put them back. Thus the leak. It should be all better now.

              OK, it seems a bit overstated to call this the worldwide debut of Bullet, but this is the worldwide web, so here goes nothing.

                  How are the new Penske shocks that SM has been using?

                    I'll have to let you know. This car has never seen the track, and I've not yet driven it in anger. They are much higher quality.

                      I don't have them yet on my SM, but I have been told by several drivers that they are a big improvement over the Bilsteins. Sounds like it was a much-needed change.

                        I find it hard to believe you could ever drive in anger...

                          I meant in the Rob Burgoon sense of the phrase.
