I will be installing a 23mm MC to feed the bigger brakes on the new car. I have heard that their are plumbing issues, and clearance issues when installing the bigger MC.
I'm looking for feedback from those that have done this. Here is a comparison of the new and old MC. I have some questions. 1) Ports 3 and 4 are the front and rear output ports. These correspond (location-wise) to ports 1 and two on the new MC. It seems that I can just transfer the hardware and lines over without any issues. Correct? 2) The locations of the feed lines are different between new and old. Is this going to be a clearance issue? 3) The hydraulic pressure switch (located between ports 3 and 4) does not have a corresponding location on the NEW MC. But there is another output port on the bottom of the MC (underneath port 1) that I can use? Any clearance issus here? 4) Does anyone know what the bolt on the top of the NEW MC is for? (between the red caps)... If I remove it, will a genie come out and grant me 3 wishes? These would be easier to answer if my car body were in the same location as my parts. (hopefully in a couple of weeks!) Thanks! Attached image(s) |

When I bought mine several years ago, it came with new gromets and tubes for the fluid supply. I installed them before bolting in the m/c and then used new Parker kevlar hose from the top to the feed lines. I also had to make a new rod to go into the back of the piston since the stock 914 one was too short and I wanted to keep the pedal in the normal position. I did not have the pressure switch for the warning light either. You might want to use a residual valve in the line for the rear brakes to eliminate any change of lockup. I adjusted the brake lights so they come on before the m/c actually makes any pressure so the cars behind me will start braking but I'm not really braking yet. Good luck
