CADILLAC DEVILLE BRAKE FLUID PROBLEM

1992 Cadillac Deville • 135,000 miles

I am getting ready to bleed my brakes on a 1992 cadillac deville. When I bleed the brakes should I leave the master cylinder cap on or off. How far should I let the fluid get before refilling the master cylinder. Should I put the fluid back in the master cylinder that I bleed or should I put new in it. I am using a hand held vacuum I read you should put some new brake fluid in the bottom cup. When I am finally done bleeding the screw should I leave the hose on the screw and tighten it or does it matter. Thanks.

Never recycle the brake fluid that comes out of the bleeder screws. Always put in new fresh brake fluid when the master gets about a 1/4 of the way down top the fluid off. Also dont remove the vacuum from the bleeder screw till teh screw is tightened back down. You can prime the cup on the vacuum pump. Another way you can bleed the brakes by yourself is with the one man bleeder. Lisle makes it what that is is a hose with a one way valve on it. So when you put it on the bleeder screw and open it and press the brake pedal it only allows brake fluid to escape. The one way valve doesnt allow air to be sucked back in when letting back up on the brake pedal.
