Spongy pedal, SS teflon lines & MC bore

[Caprimaniac]

I run single piston sliding calipers both front and rear.

Very interesting; my experience is that switching from steel to aluminium calipers makes pedal more spongy. At least some of the Wilwood- types. And SSBC are aluminium aswell, as I recall?

Maybe it's 1 piston/ sliding VS multi piston/ double row calipers?

OK; on the bleeding- I did them both at one time. There's a seperate reservoir for each of the pumps. I could try one more time just to be shure..... (The pumps are not easily accessible, so not a funny job!)

Will post again after bleeding or even changin the rear MC.

Thanks
