1995 Buick Park Avenue brake problems

My brakes didn't feel right so I took it to a brake shop and they replaced the wheel cylinder (which they said were leaking) they also told me that I would have to have the master cylinder replaced as it was going bad. My husband has replaced the master cylinder and bled the brakes 4 or 5 times (making sure the reservoir was full) and still no brakes. What now???

yes it does, and they undid the new master cylinder last night and bench bled it to check to make sure it was working (pulling the fluid thru), so he's going to try to bleed it at each tire again when he gets home tonight

Unhappy new development!!

Now I have brakes, but the brake warning light won't go off and continues to make the most annoying dinging/warning sound - any ideas????? Also if you unplug the ABS at the master cylinder the light and dinging stop while still having brakes. Do you have to reset the ABS somehow???

On many cars with ABS, a scan tool is required to operate the ABS hydraulic pump and control unit in order to completely bleed the system. You need to find a GM factory manual and get the right procedures.
