Boxster Calipers, got them installed today! Options

[SirAndy]

About time too as my Carrera brake pads were down to the metal.

The idea was simple, get rid of the Carrera Calipers and mount Boxster Calipers all around using the mounting adapters from Rich Johnson.


Of course, nothing ever goes as planned: (IMG:style_emoticons/default/headbang.gif)

First, i failed to read Rich's instructions that clearly state that you have to use a 20mm 911 SC rear rotor.

Well, i have 24mm Carrera rear rotors. The Boxster Calipers had to be machined (2mm off each of the brake pad pins) and the adapters had to be milled to center the Boxster Calipers over the wider rotors.

Then, after everything was bolted together, i recalled reading that the hard brake lines may not be long enough.
And sure enough (of course) the front brake lines were about 1" too short. Arrghhh.

McMark came to the rescue and we made two new lines. (IMG:style_emoticons/default/thumb3d.gif)

In the rear, i used banjo fittings on the Calipers (Thanks to Eric Shea for those!) and the rear brakelines were no problem.

Mark and i then bled the brakes. I was still getting some air in the front, but it was already 9pm so we decided to call it a night and i drove it home (40+ miles). The brakes actually felt fine, they seem to work great.
I'll go back to the OC shop next weekend and we'll bleed them again.

And now for the pitchers:

Post #4 and #5 in this thread show the milled down adapters to allow the calipers to be centered over the 24mm rotors.

@sirandy - Thank you. I read that and I could not visualize how inserting an adapter solved my problem. It looked to me I needed to shave 1.5mm off the face of the caliper where it seats to the flange of the strut for the caliper to go in the needed direction. Clearly, I’m missing something.

Please send pics of the back side so I might see the configuration, if possible. Thanks again!

Also, after re-reading the string I figured I’d reach out to @a914guy to get the lowdown on his adapters. Once I see the adapter in place it might sink into my thick skull. (IMG:style_emoticons/default/confused24.gif)

@davenorcal
You already have the adapters mounted to your calipers. I can clearly see them in your pictures.
I milled down the adapters so the calipers end up centered on the 24mm rotors.

And as mentioned, i also shaved down the pins.

PS: Yours don't appear to be the Rich's adapters, unless he has a new design. But it can't hurt to contact him anyways.
