In a previous update I mentioned that I swapped out my brake master cylinder for another one. I did this mainly to resolve an issue with the push rod retention method. The MC that I am currently using has a nice deep pushrod hole as well as a clip on the tip of the pushrod that retains it inside the MC. Just because everything bolted up fine, doesn’t mean that this MC will work in my application. The pedal seemed to be very high and the pedal effort is rather high. So I decided to see what was really happening at the caliper. I went to my local hydraulic hose retailer and picked up an inexpensive pressure gauge. After installing the gauge in a bleeder screw in my caliper I had a friend step on the break pedal and to see what kind of pressure was being generated. Keep in mind that Wilwood rates their calipers at a maximum of 1200psi. From what I understand, past that point the caliper starts to deflect. So here is the result:



With moderate pedal effort my friend was able to generate a fairly easy 800-1000psi at the caliper. By pushing a little harder I am sure that he was going past 1200psi. With all that being said, I think that this MC will work just fine. The pedal effort will be moderate and the braking will be excellent!
