SSBC disc brakes won't stop

Sorry I wasn't clear. Not the rear brake lights, the red dash brake warning light.

This would be normal with the rears being not working. The safety sw is doing it's job. We will turn it off later after the rears are working properly. The light is just telling you that there is a problem.

So your thinking I don't have enough
(1) pedal travel?No, I'm not thinking that,yet. But that is what the reserve test will prove.
Its adjusted all the way out with the pushrod. The pushrod is not used to set the pedal height.The pushrod is used to compensate for manufacturing tolerances, stacking up to prevent the Compensating port from working properly. If you have messed with it. we are going to have to adjust it properly.
Sounds like the rears could engage and prevent enough pedal travel to sufficiently supply enough pressure to the fronts if I understand you correctly.In a disc/ drum this cannot happen, but, now that you mention it, in a disc/disc; You know it actually might! lemme think on it......
Ok, done thinking. Nope can't happen . After the rears are fully engaged the foot pedal simply moves the rear chamber volume forward pushing the front piston out to engage the front brakes. This all happens simultaneously, so in reality there is no "after". And the rear brakes do not build pressure until the fronts do.
Phweuf, you had me going for a sec,there.

Ill have to check that out. I switched to the smaller diameter mc because I only had 500-600 psi on the front calipers with hard pedal pressure. Was told small 7/8 mc would supply more pressure and would only have slightly more pedal travel. Probably going to check the pressure with the 7/8 mc tomorrow to see if increased at all.
So if Im hearing you right your saying just open up the rear line and then see if the front are stopping the car? Then when fronts are 100% reconnect the back and bleed the rears?

Yeah I guess that sums it up, but not so fast. Since I get the idea that you used the Pushrod adjustment to get the pedal height up, I think this might be screwed up. I bet you did this after the front system was bled. That would make perfect sense.So before you go out on a roadtest make sure the compensating port is working. Refer back to post #42?
