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:

Andy - Great job and the brakes look great. What, if anything are you doing regarding brake bias? Do you intend to use your car on the track? With all that volume it will be interesting to see if you end up with a larger MC. I had a 19 and moved up to a 23/930. Food for thought and always a slippery slope...

I currently have the 19mm MC. I have to bleed the brakes again, so i can't comment on the pedal feel just yet. It did feel a bit soft after the first bleeding, but that was to be expected.

As for the bias, i have been running with a "T" for years and so far, it feels OK. The real test will be my next AX where i plan to really put the brakes to the test.
I'm hoping to get the fronts to lock up first but have enough bias to the rear to make them work hard.

We'll see how that pans out ...
