What size master cylinder would be best for my setup? I have wide A calipers up front and 914/6 gt rears?

I cannot remember for sure what the wide A was. If it is from the Carrera 84-89 I have the identicle set up front and rear. I selected the 19mm master based on a discussion with Eric Shea. Basically the front and rear pistons diameters are the same as porsche intended so you have the same front to rear bias. The results are nothing short of amazing. Stopping power is awesome. Perfect pedal travel to modulate the braking. Excellent pedal feel.

It sounds like you have the same setup as me. It feels like my pedal is a little spongy even though I have bled my brakes several times. I will try again. This may sound odd however I do not know what size of master cylinder I have. I installed a new master cylinder a few years back when I had a stock setup. I do not remember what size I installed. Is there a quick and easy way to differentiate a 17mm or 19mm mc while it is installed? |
