Brake pressure regulator Options

[watsonrx13]

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?

Tom,

For your car (and about 90% of the others out there), stock brakes, new lines, new fluid and awesome pads should throw you through the windshield at the cones course... and deliver on the lawn at Monterey.

Word of Caution on Master Cylinders: There are Chinese 19mm Master Cylinders out there. I'm not your average import hater etc. but, there have been far too many failures with these units for me to recommend them. Only purchase ATE Master Cylinders for your car. If it's under $200.00, it's probably way jacked up in price and "not real".

I know it goes against the grain for the duct tape and zip tie crowd but, this is a place where you don't want to take a chance.

Thanx Eric! (IMG:style_emoticons/default/smile.gif)

I agree on the 3rd world cheap crap parts out there! (IMG:style_emoticons/default/mad.gif) My MC is an ATE from PP (before Pat G & Paul/Nuen Vehrzen pointed me to you/PMB (IMG:style_emoticons/default/sad.gif) ), but don't recall the price as it was early last year & ordered with the rotors, lines & bits - all of which were the OEM/OES for Porsche.

With your purdy calipers, it would do well at Monterey, but I'd have to work very hard on being as anal as the CW's on here & in PCA! (IMG:style_emoticons/default/biggrin.gif)

My approach has been to do a top quality resto/repair/refresh on my 914, & therefore to use the best product available for the function overall, so I won't be messing with it again in 5, 10 or more years for ANYTHING!! (IMG:style_emoticons/default/dry.gif)

In some cases I've gone with better repro items over OE/OES/OEM - like Mark/Mikey914's bumper toppers & seals using a better rubber & better SS metal bits - since they look exactly like stock but won't rust & dimple like the OE ones.
