The only thing that he has to do every day is gets in the car and pumps the brakes up. He said the petal is soft if it sits overnight or for a couple of days. he is not sure why.Said that when they first put the brake set up in they blead the brakes trying to get rid of the soft pedal after sitting and it would not clear up. Once he "cycles" the brakes the brakes have lots of pedal and work fine all day. He is going to see if they have a make and model on the master cylinder.
This is the problem I am having with the stock in the front and the wilwood in the rear. If that guy thinks that is how brakes work and he is ok with that then that's cool with me But I refuse to put myself in a car that the brake pedal does not work first or second pump.
I drive my car on the road and the last thinkg you want is a soft or pedal you have to pump. Return roads come up real fast on some race tracks I have been to.
