Thread: Brakes don't feel 100%?

Also it can leak internally. If they bled the brakes the manual way, sometimes that kills a master cylinder's internal seals(internal leak) Hold your foot on the brake pedal and see if it sinks after a while. If not, there is probably just air in the lines.

What are you calling the "manual way" of bleeding brakes? One person pressing the pedal and other cracking open the bleeder until no air comes out? Why I'm asking is I just had my brakes all apart last week and after I put it all back together it seems a touch on the soft side, but one pump and they come up a lot harder. Without pumping once, I can still mash it hard enough to make the ABS kick on on dry pavement though. I'm going to re bleed everything for the heck of it to double check I got all the air out.
