Post air in brakes

hi,i wonder if there is somebody out there who could help me out with air in brakes problem.i have just put my A back together after renewing the front end,i have replaced the old disk brake set up with a new super stopper 4 pot set up by superbell,i can get the pedel down to one pump to get it back up,but just dont seem able to get it all out.i bleed them right through untill there is no sign of air comming out,but by the time i get round the four wheels the first one squirts air out again.i cannot find any leeks,the only other thing i have changed on the car is both front flexe hoses and one front brake line from m/c .if any body coud solve the problem for me id be very grateful. <img src="confused.gif" border="0">

Sounds like you are possibly picking up air from one of the lines or the M/C. You said you get the pedal back with one pump. I hope you are not pumping the brakes to bleed them. That is how many people bleed the brakes. It should be noted that "pumping" the pedal to bleed the brakes has a tendancy to break up the large bubbles into many small bubbles. they then combine back into large bubbles again. Since you said that you replaced a line to the M/C, I would suggest bleeding that again, then the rest of the system, while checking for leaks.

Try this. Wipe off all your brake lines and connections so they are clean. Get someone to hold the brake pedal down or wedge a 2X4 between the pedal and the seat to hold the brake pedal down so that you have pressure maintained on the brake system. Get under the car with the best light you have and a mirror and check every inch of brake line and every connection for a leak. If you find a leak you are also pulling in air.

Next after you are sure there are no leaks in the system using the above procedure, get a $6.95 one man brake blead kit and place your recovery bottle above your caliper or wheel cylinder. While keeping the master cylinder full pump the pedal up and down until you get no bubbles coming out of the bleader valve. Start with the longest brake line and work to the shortest. If you replaced the master cylinder bench blead this before you blead the calipers. I have used this method on the most difficult jobs and it has never failed. Give it a try.
