Gents,
I have done the searches, watched some video, looked up stuff, rebuilt my calipers, replaced the MC, soft brake lines, and some hard lines, new pads and hardware, adjusted the venting clearance on the rear pads, speed bleeders...probably going on about $600 all in on this brake system so far...bled , then bled, then bled some more using a pressure bleeder...still a soft pedal and red blinky brake dash light when the pedal goes to the floor. I tried to do the pedal bleed, but it didn't seem like the fluid was moving. When I switched to the pressure bleeder, the fluid started coming out...no air bubbles. What am I missing? Adjust the venting again? If I did that wrong, does it screw up the whole system? Car runs, is looking good...needs to STOP. (IMG:style_emoticons/default/headbang.gif) |

Gents, I have done the searches, watched some video, looked up stuff, rebuilt my calipers, replaced the MC, soft brake lines, and some hard lines, new pads and hardware, adjusted the venting clearance on the rear pads, speed bleeders...probably going on about $600 all in on this brake system so far...bled , then bled, then bled some more using a pressure bleeder...still a soft pedal and red blinky brake dash light when the pedal goes to the floor. I tried to do the pedal bleed, but it didn't seem like the fluid was moving. When I switched to the pressure bleeder, the fluid started coming out...no air bubbles. What am I missing? Adjust the venting again? If I did that wrong, does it screw up the whole system? Car runs, is looking good...needs to STOP. (IMG:style_emoticons/default/headbang.gif) Did you "bench bleed" the MC before installing....if not, do it. Or crack the lines at the MC. Are you thinking I have air in the MC? Another thing...my brake lights are now on the minute I fire the car up...any clue? never seen that before. We are absolutely thinking you have air in the system. So did you crack the lines at the master cylinder and bleed it? The brake light being on is likely a simple fix of the actuating rod engaging the brake switch at the pedal cluster. Typically on a new system, the very first thing I do is crack one of the lines at the MC and pump the pedal until fluid comes out. I close one line and crack the other and repeat. After bleeding both lines at the MC, I then crack one line after the proportion of valve and pump til fluid comes out. I then proceed to all four wheels and bleed. I drive the car and then bleed again. Seems to work pretty well. |
