When I press pedal brake in first time,it's deep but it's will better in the second time.It's never happen when I use hand brake and pedal brake in the same time.
And the secondary master cylinder is weak but it's still work with real caliper.
How can I do ?
Is it possible to bleeding some part of brake system ?
Example: only brake pedal with center bleeding valve of front left / right caliper.
or only brake pedal with rear center bleeding valve and rear upper bleeding valve.
or only secondary master cylinder with rear upper bleeding valve.
Thank you.
