Bleeding brakes

[X292J]

So installed a diffrent BB/MC off another car in my car, i bleeded the brakes. The pedel is rock solid. Then i turn on the car and the pedel drops to the floor and i have no or very little brakes again. Also when i pump the brakes with the car on nothing happens.
After i turn off the car and pump the brake again it seems to be good.

any say?

bleed it again. sounds like youve got an air bubble in the line.

try to solve the problem with the easiest solution first, which is bleed the enitre system again.

when you bleed the brakes you really need two people to make it work best. be sure to hold the pedal down when you release the bleeder valve.

Bleed them again. I had the same problem then I bled them again and it was fixed. Did you by chance only bleed the front and not the back?

Just follow this when you do it.

whoever is bleeding them with you may not be pushing hard enough when you open the valve to bleed it..

or perhaps there isnt enough fluid...make sure its filled to the line

I've recently learned the BEST way to bleed brakes ever... let me get my MS Paint skills up, and I'll edit this post.

EDIT:

Ok, you need to get some clear fish-tank tubing, and hook that to the bleed nipple of the caliper. Put the other end of the tubing in a soda bottle which is filled half way with brake fluid. Open the bled nipple, and begin pumping the brakes until no more bubbled come through the line.. repeat with the other 3 brakes.

The soda bottle filled with fluid will prevent any air from re-entering the lines.. and it will allow you to see air coming out of the lines.

See the attached MS Paint Power!

Did you "bench bleed" the MC before you put it on?
