[ckt1965]

have a brake problem on a 2000 malibu , i have replaced both rear lines from the front at the splitter to back ,new master cyl.,new shoes, drums hardware kit,I KEEP BLEEDING THE SYSTEM AND HAVE NO BRAKE PEDDLE ,im getting fluid at all 4 corners nice streams of it but no peddle if anyone has an idea please let me know i am ready to pull my hair out with this beast

thank you

What was your problem to start with? Why did you start replacing parts? Best advice I can give is make sure your shoes are adjusted out almost to the drum.

when we got this thing somebody had hacked the rear lines and blocked 1 of them off and now I have NO PEDAL AT ALL since all of that, also i have the shoes as tight as i can get them , i am getting fluid at all 4 but no pressure .I worked in a muffler and brake shop for many years and i am beyond sanity with this one, friend of mine said it could be the proportional valve where all the lines go into and come out of

thanks for any help

Proportioning valve would be my best guess in no leaks at wheel cylinders

Or air trapped in the abs unit, this requires the appropriate scanner to bleed the abs.

That's also very true it can be very hard to get air out of the abs without a scan tool

When you got this thing, was it towed in or was it driveable, meaning you had a brake pedal?

my daughter has a 1999 chev malibu bought a few months ago certified with new brakes recently the brake light and the exclamation light come on once in a while, brakes are firm, brake fluid fine, if the emergency brake was on even a little would that do it tks
