Re: spongey brakes
What's the history. Is it worse then before. Was something done? Is it the same as always? What?

Re: spongey brakes
Look at the top of the brake pedal arm
Just an example not necessarily your exact layout

Re: spongey brakes
how did you bleed the brakes? by using vacuum or stomping on the pedal..the last method is guaranteed to mess up your new MBC..
