We just put a set of rebuilt Girling 14LF calipers on the front of the Alexis MK14 and ran it at Mid Ohio last weekend. The car previously had 12sp calipers. I noticed that when the brake pedal is first pushed that the pedal goes a little deeper then when its pushed immediately after. So, subsequent presses are a bit firmer and a bit higher than the initial press.
Of course, if we wait several seconds, the first press will again be a bit deeper followed by firmer and a bit higher.
Not sure what the problem is. A little air in the system? A failing master cylinder?
Any ideas?
Thanks.
