Brakes are spongy

[Milly]

Okay so I've bled my brakes in the right order like 5 times. I've ran almost 2 bottles through the lines.

When I took it for a test ride you'd have to pump the brakes in order to stop. After a couple pumps you could hold it down.

New brake pads and all, is there still air in the lines or do I need new brake lines??

Thanks!

Did you replace the bmc or let the bmc run dry at some point?

[Milly]

Nope the Bmc has not been replaced, the brakes weren't spongy before I took the calipers off to paint them.. So I was thinking there was just air in it until I bled it 5 times and it didn't help much.

The Bmc I don't think ever ran completely dry but it did go below minimum at one point... Not during the last bleed though, I made sure of it..

sounds like air in the lines use one of those do it urself bleeders they are awesome.

where do i get a do it yourself bleeder?

i used the little cup thing with a bit of brake fluid at the bottom....ran a tube from the bleeder valve to the cup... had friend pump brakes, did each caliper for about 2-3 cup fulls of fluid...

Thanks for the link....read through it, and in the end it turns out it was the BMC?

I guess I'll be purchasing one from the autozone in a couple days!

did ya bench bleed the master? if you left off to paint and ran it dry it'll cause this issue. car on put pressure to the brakes, if the pedal slowly goes to the floor while applying constant pressure its the master


also when bleeding DO NOT PUMP TO THE FLOOR!!!!! EVER!!!!! I work at autozone, you wouldn't believe how many we sell just cause someone ruined the piston seal while bleeding. not taking a shot at you man, just warning people. 1/2 pumps except when you got a new or refurb'd, i just do it as to never have a problem.





Also because i work at Autozone and mentioned autozone i have to state that i am not trying to sell you anything, and any advice/opinion i have given is not necessarily reflected by autozone etc etc.....

Check around the seals on the caliper, you could be losing pressure if the seals are damaged.

I changed the bmc and the problem got better, now I only have to push it once but it goes to the floor, and slows down kind of slow... Won't lock up for sure.

People have been saying new booster?
