JoroCorona Posted November 19, 2004 Report Posted November 19, 2004 I was cruising along, going form light to light in town. The brakes were their usual perky selves, sometimes hitting ABS when I was really romping on her, but then all of a sudden they got crazy soft and the ABS wont kick on. It still stops alright, but you have to literally push the pedal to the floor. What did I do? This is my Lumina, just for the record. Quote
93CutlassSupreme Posted November 19, 2004 Report Posted November 19, 2004 master cylinder maybe? or maybe somehow air got into a brake line, that would explain the soft pedal, but that wouldn't explain the abs problem Quote
terryk2003 Posted November 19, 2004 Report Posted November 19, 2004 air cannot just GET IN there all of a sudden...if there is air in there, something is messed up...maybe the vacum booster, master cylinder...or a hole in the brake line Quote

JoroCorona Posted November 19, 2004 Author Report Posted November 19, 2004 Nah, Its not pissin it anywhere, and if the mastercylender went, wouldn't I lose brake completely? Quote
terryk2003 Posted November 19, 2004 Report Posted November 19, 2004 yeah...if you lost assist altogether...but, maybe its getting too much vacum somehow!!?...i dunno...i do know that the booster went on my mom's old '89 grand am and the pedal was all mushy and went almost to the floor before it started to stop :yikes: Quote
93CutlassSupreme Posted November 19, 2004 Report Posted November 19, 2004 Nah, Its not pissin it anywhere, and if the mastercylender went, wouldn't I lose brake completely? no. i've seen a Chevrolet Express van with a bad master cylinder, it would stop but the pedal would go to the floor, it was soft, and weak as hell. those vans have a different brake system though, it's somehow tied into the power steering pump....

JoroCorona Posted November 19, 2004 Author Report Posted November 19, 2004 Nope, never gets stronger even after pumping, thus makign me think its not the master cylender. Even if the seal went in the cylender, it would get stronger after a few pumps. Quote
White93z34 Posted November 19, 2004 Report Posted November 19, 2004 i'd guess that a brake line rusted through, but then you say its not leaking anything so that kinda throws that out the window. check your callipers, look for the boots leaking or torn. Quote
Brian P Posted November 19, 2004 Report Posted November 19, 2004 yeah check the calipers, do a once over Quote
terryk2003 Posted November 19, 2004 Report Posted November 19, 2004 i just had another thought...check the brake HOSES!!...i've seen them get bad and when you hit the brakes they will buldge out, thus making a spongey pedal! Quote
