I bought my car about 6months ago and the brake pedal felt soft from the beginning. Now I bought stainless brake lines and decided to change to ATE Super blue racing fluid. I took off all rubber lines and all the fluid from the MC poured out, I even added some cheap brake fluid to kindoff flush the lines from dirt.
Next I installed my SS lines and bled all the calipers in the correct sequence, twice. The pedal still feels soft and Im thinking either the MC is damaged of there is air in the system (mainly in the MC but I dont know how to bleed that).

What should I try? How do I bleed the MC if there is even such a thing. How do I test the booster and MC?? thanks

 

does the pedal feel soft when u have the car running?

or

does the pedal feel soft when the car is not running

 

You need to bench bleed the master. I wouldn't know how to describe how to do it and I don't have a digi cam. If you bench bleed the master and it still has a mushy pedal then I would say that you have blown seals in the master. If you understand how a master cylander works then you should be able to figure out how to bleed it.

might help some

 

nice, thanks for the backup.

 

you need to bleed the system more than twice.. if you have that much air youll prob go through alot of fluid till it gets stiff.. and you dont need to benchbleed the mc.. you didnt even change it why would you bench bleed it?. thats if its dry and doesnt have fluid in it

 

it feels mushy with the car on and hard when its off. Im going to rebleed the calipers to see if it fixes it and try to bleed the mc but Im not sure how to do with it still in the car

 

the only reason I say bench bleed the mc is because that would rule that out. I guess I just like to cover every angle. no biggie
