So I want to get a second opinion on what I have going on. I have the 12" PBR twin piston caliper setup on the Front of my SHO, and stock solid rear disk. This has been through the road course at Putnam Park without any problems (i.e. soft pedal,etc).
Sitting at a stop light the other day I noticed that I could push the brake pedal all the way down to where it is bottoming out fairly easy. Well in a not too smart fassion found a empty, straight, flat road and tried a hard stop from 60 to zero. The brakes are definatly not making nearly enough pressure to activate the ABS. Normal daily driving I have not noticed anything, so this is what I have done.
- Brakes were bled before the SHO convention this past year, and were clean.
- Read about the ABS beeding tool, and how over time if this isn't done can cause soft pedal. Purchased the tool and ran it today.
- Bleed brakes again today, RH Rear, LH Front, LH Rear, RH Front. This was done by pulling the cap off the Master cyliner and using a mightly vac tool on the bleeder at each caliper. Pulled some darker fluid out of each caliper, but nothing bad. Total bleed from the system is ~ 1 qt.
No change in the braking performance. There are no leaks at any of the hard to flex lines, or anywhere at a union that I can see, and the car had not lost any brake fluid before starting the bleeding process, so I don't think there is a leak in the system.
Thoughts, ideas, Things to look for?
