Ok, I know this has probably been discussed in many threads before. But, what is the reasoning for replacement of the Prop. valve with the "T" fitting for the rear brakes. Does the prop. valve cause more line pressure to the fronts or the rears when it is operating properly? I want to understand the engineering aspects of this modification.
I will be running "M" calipers with mythical billet hubs in the front and stock 914-4s in the rear. thanks (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) |

The corelation between a Carrera brake set up and a 914 with Carrera brakes wouldn't seem to be straight across. The Carrera has more rear weight bais, bigger tires rear to front, undoubtly transfers less weight to the front during braking...The only thing that does work is a reasonable compromise between braking force caliperwise front to rear......it's close enuff to work out on a 914.....if you have a adjustable valve as less pressure will be required in the rear on a 914 due to the reasons above. |
