STILL NO BRAKES! Options

[JHop]

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)

Check your brake hoses. If they are 40+ years old, they will be constricted.

I ran across a situation recently where the internal bleed passageway down to one side of the caliper bores was blocked with crud/rust so only one side of the caliper was able to bled. The result was spongy to no brakes.

I had to split the caliper and run a wire or very small drill through the passageway to clear it out. With the passageway clear, the brakes bled normally and I had a solid pedal.

While the image below is of a bicycle caliper, the idea of the passageways is similar to how our calipers passageways are run. If they aren't clear, the caliper won't bleed.
