Spongy Brakes

[NOT A TA]

Was the pedal OK before the new master or did you install it when you installed the Wilwoods and Right Stuff discs? Were you ever able to get the parking brake adjusted so you had 1/2" or less travel of the park brake actuating levers on the calipers?

There are folks here who know far more than I ever will about brakes who might have answers for you but more info is required. Many knowledgeable people don't want to start a week long fishing expedition asking questions to get the info they need to help you. Take some time to list in detail everything you've installed and the methods you used to install & bleed include pics of everything. Then you may get the answer you need.
