Loss Of Brakes

[Michael Postel]

I am working on my sisters 2003 S40. It has about 70000 miles in it. The dealership in El Paso, had destroyed a few parts and neglected to maintain many systems. One of which, the brakes. I recently tried bleeding the brakes, only to notice the driverside rear bleeder valve has been rounded out. So I proceeded on, only to finish, half-way. The brakes prior to this were gripping, just not quite as well as they should have....the fluid was pitch black! After a few pumps, the brakes gripped perfect. While turning the key, I heard a whining noise, and soon enough all the pressure in the brakes, somehow was lost. The pedal went to the floor.

I was thinking of replacing the bleeder valve and re-bleeding, but thought it would be smart to check ideas first. Has anyone experienced this? I'm about to check alldata, so help me with this swedish disaster.

Welcome

I'm guessing you just opened the bleeders on the brake calipers themselves and opened no other lines elsewhere?

Is your reservoir full? The noise you heard was probably the pump activating just doing what it does. Did you think the braking performance was poor to begin with? If so are there OEM pads and rotors on the car or aftermarket. It possibly sounds as if you created other issues? All these questions need to be asked in order to correctly try to help?

when you bled the brakes, did you make sure there was still fluid in the reservoir? if air gets into the master cylinder it could cause the pedal going to the floor because you're compressing the air in the system. If air is in the master cylinder you have take it out and bleed it.
