inline4 Posted April 18, 2009 Report Share Posted April 18, 2009 my buddy who had all around discs mentioned that he had to double pump to get brake pressure... and it looks like mine does too. is this a common thing? or is there something wrong? Quote Link to comment
datzenmike Posted April 18, 2009 Report Share Posted April 18, 2009 This is a problem because in a panic situation there's no time to double pump. Air is trapped in lines or flex hoses swelling under pressure. Look at each flex hose while someone holds the brake down hard. If you see swelling, replace them or replace with braided lines. If they check out, bleed the brakes to get the air out. Quote Link to comment

inline4 Posted April 18, 2009 Author Report Share Posted April 18, 2009 i had the same problem until i changed the M/c to a bigger one hmm... i wonder how much it would cost someone to bleed the lines. chris swears there is no air in them. mc is a 280zx unit. Quote Link to comment

freaky510 Posted April 18, 2009 Report Share Posted April 18, 2009 do you have a line that runs from your intake to your brakes m/c booster Quote Link to comment
inline4 Posted April 18, 2009 Author Report Share Posted April 18, 2009 do you have a line that runs from your intake to your brakes m/c booster I have a KA. I suppose I could find a vacuum line and hook it up. there is no booster.... Quote Link to comment
freaky510 Posted April 19, 2009 Report Share Posted April 19, 2009 I have a KA. I suppose I could find a vacuum line and hook it up. there is no booster.... no booster no need for a line the booster runs off vac from the intake :eek::lol: hhhhmmm must have a air pocket. did you start with bleeding the M/C then go to the right rear then left rear then do the front right then left always start with the furthest caliper from the m/c. My 02.$ is that the wilwood require more pressure and so do the zx brakes maybe try a bigger M/C Quote Link to comment
