Car has no brakes.

[Slick2500]

Working on my friends car kinda scratching my head on this one.
Car is a 2000 Chevy Impala.
Car has no brakes, nothing, you step on the pedal and it just goes straight to the floor.
Both the master cylinder and brake booster have been replaced.
Brakes have been bleed, when you open the bleeder and press on the pedal fluid poors out on all 4 corners.
Any help would be appreciated.

you bench bleed the master before installing it?

[Slick2500]

I am assuming he did. Btw car had no brakes before we replaced things, the brakes one day just stopped working.

[Scottydoggs]

id ask if he bled it. most dont know you have to. then re bleed it even if he did bleed it, then re bleed all 4 brakes.

now that its bolted on, easy way to bleed it is to use a wrench and a rag wrapped around the line nut, pump the pedal like you would for a caliper, then crack the line nut off the master, do that 3 or 4 times, or until you stop hearing air blow out it.

do the rear line first, then the front on the master.

The ABS valve is probably full of air.

What line nut am i supposed to put a line wrench on?

[Scottydoggs]

line nuts off the master that lead to the abs pump.

[Slick2500]

Kk Ill go check it out.

the rag just controls the spray of brake fluid. a small cup under it cant hurt either if you care to not make a mess. most of the time its a mess.

the new master should have come with two clear plastic tubes and threaded fittings that fit where the hard lines thread into the master, you fill the master and clip the tubes into the master under the fluid level, then push the master plunger with a screw driver till no more air bubbles come out the tubes. aka bench bled.

I've also seen the proportioning valve get air stuck in it a few times. My brother had a 79 Bronco he just went mudding with and one day lost rear brakes. After several attempts to bleed we made a few phone calls and someone told us to open both bleeders on the rear and just stomp the brake pedal as hard as we could, then hold it while someone closes both bleeders and repeat a few times.

It worked, after about 3 times we got rear brakes back.

I had no brakes after a similar thing, co me to find out, I had put the calipers on the wrong side of car, the bleeder screws should be on the top of caliper
, if they are on the wrong side, the bleeder is on the bottom which is wrong

I'm done trying to help him with this, he won't listen and keeps trying to Ghetto rig everything.
He did this last night, I looked at it and just had to walk away.

seems legit....but do they work now? lol my guess is no.

you guys ever bleed the master?

[Slick2500]

Leaks fluid out. I told him either buy all new stuff or go to the junk yard and pull all the stuff off an Implala. All the stuff he replaced he pulled off a Caviler.........
I doubt he did.

[Scottydoggs]

id tell him to call a tow truck lol

[ericspecullaas]

i dont think he knows the meaning of safety.

[Slick2500]

I give up, there is a reason he has 10 cars and none of them run.

That should have been a sign before you started to help him.


Jesus Christ I'm so sick and tired of people rigging **** on their cars. That whole master cylinder ghetto rig is gonna kill someone.
