    Brake problem on 96 Fleetwood

    Hello all my rear brakes do not work at all and my abs light is on and had been on since I bought the car, I took apart the brakes and cleaned the cylinders but noticed I'm not getting fluid, I thought maybe the porportioning valve?? Any body have an idea??

    Can you please elaborate on the EXACT steps you did to "took apart the brakes and cleaned the cylinders"? Back brakes?

    Yes back brakes, I took the drums off took the springs off, pulled off the rubber boots on the cylinders pulled out the caps and lightly sanded the cylinder just to make sure they had a smooth surface, put back together and tried to bleed but am not getting fluid to rear

    These rear brakes are just a pain. Technically, you should have a leak if you cant get fluid to the rear.

    And if you have no brakes at all. There has to be a massive leak somewhere.

    I don't believe there's a leak cause the fluid has been at the same level for months

    The fluid is at the right level currently? But there's no braking action at all?

    Yes the fluid is at proper level and there is zero braking action on rear, front works fine, my car seemed to not stop as good as it should and my front white walls seemed to get dirty real quick so I jacked the rear up put her in drive and applied the brakes and the wheels just keep spinning as I suspected

    Either your master cyl is not working right, your prop valve is jammed to one side or you have a leak. I bet, if you hooked up a vacuum pump to the rear cylinders, it wont hold a vacuum meaning you have a leak. My guess is that it leaked out under the C-pillar or A-pillar and has been dry for a while so you dont really notice any fluid.

    Something might happen inside of ABS hydraulic modulator. A valve does not open and let fluid flow to the rear brakes. I would disconnect the rear brake lines from the modulator to make sure there is fluid coming out of the valve responsible for both rear brakes.

    The front pads on my '96 were down to metal when I first got it so I replaced them. A couple weeks later they were down to metal again and they always smelled hot. Being new to Fleetwoods I figured they just didn't stop very well, but investigated anyway. Turns out the previous owner must have replaced either a wheel cylinder or a leaky line without bleeding the brakes. I had no braking action in the back at all. I replaced the shoes to no avail. Finally I bled the air out of the rear and that was the trick. I couldn't believe how well the car stopped once all 4 wheels had brakes.
