Eric's ad selling the 912 rear calipers started a discussion about the brake pressure regulator. I'd like to continue that discussion. Eric mentions that he wouldn't replace the regulator with a 'T' fitting. What I would like to know is how could you test the regulator off of the car? At $300 - $400 a piece from the dealer I would like to test mine before I purchase a new one.
Also, Eric mentioned that the front calipers shouldn't be used on the rear, even with the regulator. Is there any problem installing a set of rebuilt rears on and not installing the parking brake cables? Any thoughts and suggestions are welcomed. BTW, I'd like to keep this discussion only for the 4-lug wheels. Also, what are the thoughts about replacing the master cylinder with the larger one how does that effect the brake biasing? -- Rob |

For a V8 I would start with the regulator in place. The reason for the regulator is so the fronts lock up first and induce under steer instead of over steer (potentially very quick over steer with the additional weight of the V8 in the rear).
With the weight in the middle of the car (as opposed to behind the rear axle) I wouldn't expect the weight of the engine to affect the balance by too much. And then things like non-stock tires sizes, etc change the balance, so real world testing is the best approach. But I would start the the valve in there. Just my 2c (Canadian though). |
