I instaleld a new MAster cyilinder in my car today.. I bench bled everything out ETC ETC... THen proceeded to go about the regular bleeding routine. ABS, RR,LR, FL, FR.... etc etc... I got the pedal extemely hard... with the help of myself and by 2X4 method... the pedal was Firm.... and all calipers shot out a steady stream.... durring the process... but when I go to turn the car on.. the Pedal droped signifigantly... and I checked the resivoir and the brake fluid I topped off after I completed the last caliper, had dropped quite a bit... what gives??? My Brake light is on... and I'm baffled...

What might be the cause of this??? I remember the last time the car was bleed... I took her to the dealer... and they had a rough time... they ended up turning the car on and off while they bleed it...??? is there somehting I"m missing here.... btw I'm using a Haynes manual for reference points.

 

When I replaced my brake lines it took forever to bleed the system. Like a whole big bottle of brake fluid. Assuming its a good master cyinder, just keep at it and eventually it should firm up.

 

well, first of all... the pedal will be easier when the car is started because of power brakes. the power brakes don't work until u start the car, therefore, making the pedal softer. lol the once u start the car, the power brakes are pushing the fluid into the lines more effectively which would, in a lot of cases, bring the fluid level down some in the master cylinder. but when u bleed brakes, you're "supposed to" start farthest away from the master cylinder and work forward. RR LR RF LF should be the order, but it really shouldn't matter. i bled them in opposite orders for a long time and the brakes worked fine.
